FAll fasteners execute the same function- mechanically adjoin and secure two or more parts together. To choose the right fastener for your project, it is essential to understand the distinctive types of functional fasteners such as nuts, bolts, screws, rivets, etc.
Nuts are available in a bunch of shapes, materials, sizes, and thread designs. Although your choice of nut is somewhat limited by the bolt option – especially in size and threading – you still have to choose the nut head shape and the material that best suits your application.
Bolts are one of the most versatile structural fasteners available in a wide range of configurations to suit diverse materials and strength requirements. They usually require an integrative nut or a tapped mating part and a drilled hole for installation. Unlike screws, they are generally not tapered.
Types of Nuts –
- Coupling nut: The joining nut is a long cylindrical nut with two male threads. This component can be used to add length to the installation.
- Hex nuts: Hex nuts are hexagonal. These nuts are very versatile but require a wrench for installation. Finished hex, heavy hex, semi-finished hex, hex jam, hex flange, and slotted hex are the usual types.
- Flange nuts: Similar to the flange bolts, the flange nuts have around the flange that acts as an outer washer and allows for greater load distribution, mentioned by Best nuts bolts manufacturers supplier.
- Square nuts: This head shape increases the surface area of the fastener and the amount of friction it experiences and reduces the risk of loosening.
- Wheel nuts: Wheel nuts are a wide variety of nuts, used in automotive wheel applications.
- Locknuts: Locknuts are available in many shapes and sizes to firm other nuts and prevent them from self loosening.
- Slotted nuts: They are designed in such a way that slotted nuts can be attached to a locking mechanism with a cotton pin or safety wire.
Types of Bolts –
- Carriage bolts: Carriage bolts are fitted with the domed or curved head at the base of the square, which prevents post-installation from turning. They are typically used with masonry and wood.
- Square Head Bolts: Square head bolts are defined by their head shape like hex head bolts – i.e. square. This head design simplifies tooling gripping and allows for easy installation.
- Flange bolts: Flange bolts are a special type of hex head bolt that acts as a washer to distribute the load more evenly with the integrated flange.
- Plow bolts: Similar to carriage bolts, some plow bolts have a rectangular countersunk top. Others have a dome design. These bolts are ideal for heavy-duty applications such as industrial machinery.
- Allen Bolt: Socket head cap screws have a flat chamfered top surface and smooth or bent cylindrical sides. These are high strength fasteners intended for high demand mechanical applications using special alloy formulations.
- Hex head bolts: Hex head bolts are a wide category of bolts that require installation with a wrench with their hexagonal head-shaped features. They are available in very long and threading materials, expounded by hex bolt manufacturers in India. Hex head cap screws have a tight end and are the most common type of hex bolt.
Types of Washers –
- Beveled washers: Beveled washers are formed on a slightly angled surface, which allows objects that are not parallel to each other to join.
- Lock washers: Lock washers come in many shapes such as helical, tooth rings, angle, or spring, each designed to avert the slippage of fasteners in the required applications. They are most commonly used in environments that experience high-level vibration.
- Structured washers: Structured washers are one of the available heavy-duty washer options. These thick fasteners are designed to withstand the high load stress of the structure.
- Flat washers: Flat washers are the most ordinary types of washers. For better load distribution these provide a larger surface area.
Types of Screws –
- Sheet metal screws:
Sheet metal screws have sharp cutting threads that can be cut into sheet metal, wood or plastic commented by Screws fastener manufacturers. It has a full threaded shank and sometimes has a notched point on the tip to help in the removal of the chip during thread cutting.
- Self-drilling screws:
Self-drilling screws have a sheet metal thread with a self-drilling cutting point for drilling through 20 to 14 gauge metals.
- Wood screws:
These are partially threaded with large cutting threads and a soft shank. They are designed to slide through the wood on top and pull all the boards together.
Types of Rivets –
- Large flange POP rivets:
Larger flanges pop rivets have a larger washer than a standard POP rivet. Also known as blind rivets, they are used to fasten two pieces quickly and efficiently. Large edge POP rivets consist of tubular, cap, and mandrel; the length of the mandrel is removed during installation.
- POP rivets (Open End):
POP rivets, also known as blind rivets, are used to fasten two materials quickly and efficiently, stated by fasteners manufacturers in India. POP rivets consist of tubular, cap, and mandrel; the length of the mandrel is removed during installation.
- Last closed POP rivets (closed):
Closed-end rivets are different from the standard blind pop rivet, which has a closed-end feature that creates a watertight seal.
Other Fasteners –
Acoustic wedge anchors are used to anchoring and secure suspended wire to thick or hollow structures. The fastener is inserted into the pre-drilling hole and then hammered to extend the crack to keep the anchor in place.
Dowel pins inserts are made on pneumatic dowel tools and come in pre-cut diameters and lengths. They are cylindrical with slightly curved edges. They are used in many applications and industries such as joint strengthening, aerospace, furniture building, shelf support and are used to make models and toys.
A threaded rod is threaded without ahead and is available in many materials and grades. This threaded rod used to fasten anything from an anchor bolt and to electrical or plumbing fixtures from the roof. In drop ceiling applications these are often used parts.
Fasteners are available in a wide range of finishes and materials. Choosing the proper material and material finish for fastening applications is as vital as selecting the proper size, type, and shape, interposed by Top Fasteners Manufacturers suppliers in India.
Aluminum, carbon steel, and other alloys are the most common fastener materials. However, manufacturers also use alternative materials such as plastic and brass for fasteners intended for specific applications. Finishing options are also available for the betterment of functional or aesthetic properties,
