A taper nut is a type of locknut that has an undersized root diameter. This creates interference between the nut and the fastener, plastically deforming the threads on the fastener. Due to this deformation, they are usually only used on permanent or semi-permanent installations. A variation of this nut is the tapered nut. It utilizes a tapered thread to achieve interference. At HELLARY it is available in different materials like stainless steel, alloy, nickel, and many more.
A wing nut or a butterfly nut consists of two large metal wings, one on each side. These wings are applied for easy tightening and loosening using hands, without using tools. The benefit of wing nut is its more ergonomic design that has two tabs that look like wings. It makes it easier to install and remove. Wingnuts are also available in several types as classified by the American Society for Mechanical Engineers (ASME). Type A wing nuts, for instance, are cold-forged. Type B wing nuts, on the other hand, are hot-forged. There are also Type C wing nuts that are die-casted, as well as Type D wing nuts that are made via metal stamping.
These are the fixing screws commonly used to secure a material within or with another material without using a nut in contrast of the typical assembly of nuts & bolts. Allen grub screws are completely threaded and flawless designed to function effectively much more than nut bolt assembly where the look of the final assembly is important, such as furniture assembly. Due to these features, Allen grub screws are well working in the applications where a flat surface is essential, such as handles, grips, surfboard fins, and furniture or machine assembly.
These screws are using a very advanced technique for their application and are very difficult to crack.

CSK Phillips head self-tapping screws are known for their high strength and durability. To make an ideal assembly, the countersunk variation of the Philip screw has to be used in conjunction with a countersunk hole. It is mostly used for sheet metal applications and also for machines and electrical component assemblies. An essential characteristic of these screws is the well-spaced threads and pointed tip, which is called the gimlet point. These screws are very helpful in applications where there is a need to bear more wear & tear and also more corrosion resistance. HELLARY offers screws in stainless steel, carbon steel, and alloy steel.
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.
These screws are known for their incredible high strength and versatility in their application in multiple materials at diverse angles. Though these screws find their main application in the fastening of drywall to the projection on walls and roof beams. Fine thread types are employed for the fastening of drywall to metal objects, where's coarse thread types are used for wood to drywall fastening. This difference in application is due to the difference in surface and gripping power of each type of thread. HELLARY offers you these screws in different variations as stainless steel, carbon steel, and alloy steel. These screws have been designed to bear more wear and tear while also making them more corrosion resistant
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.
Hindi The Phillips Pan Head Screws comes with a straight slot on the head and can be drilled or removed using a screw driver. This ensures minimum damage to the surface of operation. They are commonly used in the automobile industry as well as in machinery equipment installation. These screws mostly find their application in metal to metal or high-density timber-to-metal fastening. It requires a pilot hole to be drilled before using the machine screws. HALLARY has a stock of these screws in several sizes depending on the customer requirement. We have stock of these screws in several sizes depending on the requirement.
A self-drilling screw is a type of self-tapping screw that also features a drill point. self-drilling screws have a point that acts as a drill bit and sharp cutting threads that tap the hole during installation. Self-drilling screws are a commonly used variety of screws for quick drilling into both metal and wood. A self-drilling screw can typically be identified by its point and flute (notch) tip. Self-drilling screws do not require a pilot hole, which accelerates installation time and lowers the cost and need for additional drill bits. This cost-saving feature makes self-drilling screws the clear choice for metal building construction. These screws rarely require lock washers or other types of locking fasteners to prevent loosening.
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.

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.
Hollow rivets are also known as Semi-tubular rivets are similar to solid rivets, except they have a hole. The purpose of this hole is to reduce the amount of force needed for application by rolling the tubular portion outward. The riveting process is similar to that of the semi-tubular rivet but holding is weaker because the inner diameter of the rivet is entirely hollow. hellary offers these rivets in different finishing and materials like Steel hollow, Aluminum hollow, Stainless steel, Brass, Copper, etc.
