Types of fasteners

Fasteners

There are many different types of fasteners, each with their own purpose. Fasteners can broadly be categorised as either Permanent or Non-Permanent. Affixed Fasteners, such as rivets and nails, are single-use fasteners that are meant to join two or more objects together, either permanently or non-permanently. Non-permanent fasteners can be threaded (bolts, screws, etc.) or non -threaded (pins, retaining rings, etc).

Threaded Fasteners

There are three main types of threaded fasteners: 

Bolts, Screws and Studs. 

Bolts have a head on one end and are threaded on the other. 

Screws are similar to bolts, but have a threaded head on both ends. 

Studs are used to join two parts with internally threaded holes, together. 

Fastener threads are standardised to two major standards: ISO (Metric) and ANSI (Unified) also, the majority of common fasteners are right-hand threaded, although left handed products can be manufactured upon request, and we at fasten specialise in it. 

Types of Threaded Fastener

Types of Bolts and Set Screws. 

Bolts have a hexagonal head with a thread, and can be used either in conjunction with a nut or in a threaded hole. U-Bolts are used for attaching round objects such as pipes and tubes to a wall or other surface. Self-tapping screws tap their own thread. Grub screws are a special type of screw which usually do not have a head.

Nuts

Hexagonal nuts are used in conjunction with a bolt to clamp two or more. The most common type of nut is a Hexagonal Nut, there are different types for use in different applications. These are by far the most common nut with an internal thread, these are the ones with a hexagon shape. These cone shaped nuts feature a hexagonal gripping point which snaps off when the maximum torque has been reached, leaving just the Commonly used often in applications where the nut needs to be locked in place.

Washer

There are several different types of Washers, each with their own uses. Washers are normally used between the head of a bolt, screw or nut and the material they are holding tight. These were designed to increase the bearing area of the head whilst also protecting the material underneath from damage. Washers are also used to stop the bolt from vibrating loose and to create a greater bearing surface and prevent pull-throughs. They are also commonly referred to as Penny Washers or Fender Washers and feature a small inside diameter hole. The most common type of washer is the Painted Washer.

Rivets

Rivets come in the permanent fastener category, once removed, they cannot be reused. Most commonly used to adjoin metal sheets and plates. They are very versatile and cost-effective. Large Flange Pop Rivets, also known as Multi-Grip Rivet rivets, are used when joining materials with differing thicknesses, which would normally require multiple rivet sizes. The rivets are used in a number of industries and applications but are most commonly used in the metal industry.

They can also be used in car wiring and power tools, among other things. The Riveted rivet is a type of rivet.

How can make sure you have the right grade

When chosen correctly, a well-designed alloy will support a known load. Chosen badly, the anchoring bolts or screws will fracture and snap under that load. Stainless steel fasteners are the nuts and bolts that tether everything, whether large or small. Manufactured from differently graded metals, stainless steel bolts can’t just be picked from any old

Difference Between Screws and Bolts

The difference consistent with a thesaurus is that there’s no difference as bolts and screws are considered synonyms of each other. While it might be easy to club these definitions together (it would make our job easier!) there are literally significant differences which a user must remember before making a decision. It is true that,
