Spring nuts are one-piece, self-locking nuts that secure screws and prevent them from loosening due to vibration. Long spring channel nuts are used to secure screws in framing channels, cable management conduits, and ducting systems. They consist of a nut with grooves on the side that fit over the side of the channel edge and a screw hole. Tightening a screw in the nut causes teeth in the grooves to lock into the channel edge, holding the nut in place. spring channel nuts are used to place and secure fittings, electrical panels, junction boxes, or piping clamps within channels or conduits.
Square weld nuts have four small projections in their back ends to facilitate their welding onto the surface of other metals. The most significant advantage of using these nuts is that they can be welded into even imperfect and irregular surfaces without losing their balance. The vast majority of weld nuts are manufactured in low carbon steel or stainless steel. They come with a pilot hole using which fasteners can be inserted. The pilot hole is used for precision feeding of fasteners, allowing them to be inserted quickly and accurately on the metal. These nuts are used in automobile and other industrial applications. Aftermarket products such as zinc plating are sometimes used to coat low carbon weld nuts giving it the rust-resistant properties of stainless steel at a substantial cost saving. In addition to possessing very high shear strength, they can also be used in applications that need to resist extremely high torque. At HELLARY it is available in stainless steel, carbon steel, and alloy steel.
Coach screws have their main application in joining the metal with timber and also to secure heavy timber parts. we offers these screws with specification as square or hexagonal shaped head and specially designed to make its use more convenient with any plier, wrench, or spanner. It is available in length ranges from 40 mm to 110 mm and thickness varies from 5 mm to 12 mm.
These screws are known for their self-drilling point that will drill and thread without the need for pre-drilling. These screws are designed for drilling their own hole into softer materials such as wood and plastic so they don't need a pilot hole. Hex head self-tapping screws are used for sheet metal to sheet metal fastening. The main advantage of the self-drilling screw is that it won't get stuck in the material and break off. Albeit it is required to use a washer with the screws to ensure that the structure doesnot loosen up over time. In HELLARY these screws are available in different finishes. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear.
The Hex Coach Screw is also known as a lag screw or heavy-duty screw which has a square or hexagonal head and often knows as one of the toughest non-industrial screws. These screws are externally threaded cylindrical shaft that tapers to a point at the tip. They are primarily used for holding together heavy timber, fixing metal to timber, and in some cases masonry or concrete. These screws are generally manufactured by cold forming and hot forming. They can be used for fastening dense timbers with other dense timbers or thin metals. To stop the coach screw from becoming stuck in wood, rub the threaded shaft with hand soap. The screws come in a huge size, with a length of one inch and a thickness of a quarter inch. In addition to this, they have coarse threads which do not run the entire length of the screw. In HELLARY the coach screw is available of steel material and offered in a number of different finishes like stainless steel, bright zinc plated, green organic coating, hot-dipped galvanized, etc.
A machine screw is a screw with a slotted head or socket heads often used for fastening metal parts securely together in various types of machinery or construction. Machine screws are unique, though, because of their size. These are used in threaded holes and are likely to end up with a stronger joint.
A self-tapping screw is a screw that can tap its own hole as it is driven into the material. Self-tapping screws come with a sharp, piercing tip or a flat, blunt tip. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in relatively soft material or sheet materials, excluding wood screws. The sharp-tipped screws are designed for drilling their own hole into softer materials such as wood and plastic so they don't need a pilot hole. Other specific types of self-tapping screws include self-drilling screws and thread rolling screws. The advantage of the flat-tipped screw is that it won't get stuck in the material and break off.
Wood Screws
HELLARY offered a wide variety that has numerous applications in industries like Construction, engineering, and many more. We find bifurcated rivets in the market in the name of the split rivets. The usage of these rivets mostly to join softer materials such as textiles, leather, plastic, or wood.
Blind rivets are also known as pop rivets, are cylindrical nail-like fasteners along a mandrel. These rivets are mainly used in that utilization where there is unreachable to the rear side of the joint. Rivets have a two-piece assembling; one is called the rivet body, and another is stem or mandrel. These both Pieces are pre-fabricated and ready to use. The main advantage of rivets is that there is inaccessible to over or under-torque a rivet. Unlike other types of rivets, these rivets can be used to fasten wooden or plastic materials aside from metal. The majority of them are used in RVs, Trailers, Aircraft, Machinery, Jeans, Small Electronics, Structural Beams, Battleships, and Submersibles.
Solid rivets are among the simplest, most reliable, and oldest types of fasteners. It is a two-piece rivet that can be used to join two or more materials of different thicknesses. These round-headed rivets were commonly used in large structural work where strength is needed. Snap head rivets are widely used in various industries like manufacturing and construction. Snap head rivets have applications where you need a permanent joint. Also, these rivets are used in traditional boiler-making, shipbuilding, and bridge girder construction.
The conical washer also known as Belleville washer, holds tight where heat or vibration might shake standard washers loose. The conical washer has a cone shape that compresses against the underside of the bolt head and into the furnishing material. Conical washers can be reused, repeatedly, as long as they are not damaged. They are commonly used to bear remarkable high loads in small areas. These washers are very frequently used in different industries because they can absorb and dampen shocks and vibration as well. There are several advantages of using this washer likes - Vibration Control Pre-Load Increased Load Increased Deflection Spacing Dampen/Absorb Shocks
Serrated lock washers increase the friction between the bolt head/nut and the mating surface. They do this by gripping into the mating surfaces. Please note that these washers come in two different types - internal toothed and external toothed. Serrated lock washers are installed between the bolt head/nut and the mating surface. And when it comes to loosening resistance, the externally toothed washer does a better job than an internally toothed washer. But the internally toothed washer comes with greater locking abilities. It can also allow the washers to withstand extremely high stress and force. In both internal and External types, the teeth bite into the joint material and create a holding pressure that doesn't loosen even during continuous vibrations. In most cases, a combination of both the fasteners is used to secure smaller objects in place. In HELLARY it is available in different materials stainless steel, carbon steel, and alloy steel.
Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. This type of washer can be used, that supposed prevent losing and spring action and edge that digs into the screw-on the reverse. Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device.A spring washer assembly is placed under the nut to prevent the loosening of the nut.
Square Washers are also known as construction square plate washers. Square Washers are typically thin pieces of material with a hole in the middle that is used to distribute the load of a threaded fastener, such as a screw or nut.
These bolts have their main application for pressure vessels, valves, flanges, and fittings for high temperature and pressure services, and other different purposes. we provide many different types of finishes, like - plain finish for ordinary applications hot-dip galvanized zinc plated.
Double-end stud is threaded rods with equal thread length at both ends. Double-end studs are used for high-strength bolting. There is a different type of double end studs available in the market that has reduced shank diameter as designed for special bolting. Both ends have chamfered points, but round points may be furnished depending on the purchaser's requirement. Hallery offers double-ended studs according to the customer's given specifications and dimensions. According to the information given by the purchaser, the product is fabricated.
A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends. The fully threaded studs have no head, are threaded along their entire length, and have a higher tensile strength. The thread may extend along the complete length of the rod. They are designed to be used in tension. Threaded rod in bar stock form is often called all-thread. These studs are usually fastened with two nuts and used with objects that must be assembled and dissembled quickly.
Spring dowel pins are incredibly high strength pins that come with high durability and a long life expending for several decades. They are manufactured with a diameter slightly greater than the drilled hole through which it is to be inserted. The elasticity of these pins then applies a radial force across its length. Pins contain a slot that allows compression when inserted into the hole. The spring pin is used to assemble the parts without a screw. This makes it one of the most valuable and straightforward fastening systems in the market. At HELLARY it is available in stainless steel, carbon steel, and alloy steel.
