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. Its strength can further be enhanced by changing the screw thread design of an ordinary chipboard screw and may act as a claw-cutting chipboard nail. Its appearance is generally black countersunk head, semi countersunk head, round head, etc. HELLARY offers you the wide specification of these screws like 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 6 mm, and most regularly as 4 mm, 5 mm, 6 mm for everyday application.
Self Clinching screws also called clinch fasteners are specially designed for their application in the ductile material. It is intended to displace the host material around its mounting and become an eternal part of the unit into which it is installed. Its main application is for very thin metal sheets where secure fastening is not possible by any other method. Even though it is recommended to use in thick metal sheets up to a certain gauge due to its low cost and reduction in final assembly operations. Its compact design and low profile give a neat appearance to the final unit.
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 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
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.
Truss Head Phillips Self Screws
Wash basin screws
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.
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.
Machine washers
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.
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.
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.
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.
Splits pins are known as a roll pins. Split pins are commonly used to fasten a shaft or similar component in place. It is a piece of flat spring steel that is rolled where 2 edges are almost touching where. When it is forced into a hole the spring tension holds it fast. They are also used to keep machinery aligned. The split pin is placed through a hole and the tines of the pin are then bent to hold the pin in place.
