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.
Plain Washers are also known as Flat washers and their work is to distribute the fastener's load while reducing heat and friction during the tightening process. They can also be used as spacers, as is common in industrial and domestic applications. Plain washers do not have a locking function, rather they are used to protect the mating surface from damage. Plain washers can also be used when the hole is bigger than the nut. The main role of flat washers is to increase the size of a screw's bearing surface area and reduce the surface pressure applied on the fastened object. The most common type of washers is plain washers, also known as flat washers. Looseness can result when the bearing surface sinks under the surface pressure, so using a flat washer to reduce the surface pressure is very effective.
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
Machine washers
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.
A serrated washer is also known as Vibration Proof Washers. Serrated lock washers increase the friction between the bolt head/nut and the mating surface.They are available in various sizes to fit bolts or screws.Serrated Washers are fitted internally to the equipment before a lock nut and act as an anti-vibration device to prevent the Cable Gland or accessory from inadvertently loosening in service.Often used on cable gland entry threads, these washers come in stainless steel as standard but can be made in a number of materials upon Customer request.
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 Taper washers are known as square or half-round, Taper washers are designed to be used on channel sections, underneath nuts with tapered flanges to enable the bolt assembly to fit square when tightened. At HELLARY it is available in different materials like stainless steel, Alloy, Non-ferrous, etc.
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.
Star washers are a specific type of washer designed to increase the locking force as well as torsional resistance by resisting torque applied by the nut, preventing it from unscrewing or separating. At HALLERY these washers are available in stainless steel, plain, or zinc plated finishes.
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.
Dowel pins are industrial fasteners that are used to join two or more items together. They are commonly available in imperial or metric units. They also maintain precision alignment, ease insertion, absorb hole tolerances, and prevent interlocking. Hollow alignment dowels reduce weight and cost, plus simplify assembly. For a firm fit, the hole should be exactly the same size or slightly smaller than the dowel's diameter. dowels are commonly used in furniture. They can also be applied as hinges and simple axles. They are short, cylindrical rods made of various materials including wood, metal, and plastic. Dowel pins can be tapered, slotted, grooved, or otherwise altered to change their mechanical properties. They are commonly available in imperial or metric units.
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.

Anti-theft bolts are primarily used in industries where robust permanent security fixings are required. Therefore, it is widely used in power transmission towers like electric and mobile towers. Anti-theft bolts have their application as security screws in solar panels, jails, security fencing, etc. where temper proofing is a vital feature.
A button head socket cap screw is a sort of cap screw along with a cylindrical head and hexagonal drive hole. A button head socket cap screw is most repeatedly operate with an Allen wrench.
