The Different Types Of Fasteners And Their Uses

Fasteners are tools that are commonly used to connect materials. Fasteners are a fairly broad category of tools, such as screws, nuts, and bolts, that all serve the same purpose: to mechanically hold objects together. A fastener is a hardware device that mechanically joins or fixes two or more objects together in many engineering-related applications. They are regarded as a viable alternative to welding.

ASTM A194 Stainless Steel Fasteners create a non-permanent connection. In other words, if you use a fastener to connect two components, you can remove them without causing any damage to the separate pieces. Though most fasteners form a non-permanent joint, this does not imply that you only use fasteners when you won’t be able to disassemble something, nor does it imply that the joint is in any way weak. Fasteners can hold together objects that are subjected to a great deal of stress. That means they’re a great choice for both permanent and non-permanent joints, providing versatility for whatever project you’re working on.

Mechanical fasteners, also known as fastening hardware, are widely used in a variety of industries such as automobiles, construction, aircraft, agriculture, machinery and appliances, infrastructure, and so on. Fasteners are made of stainless steel grades like the 200 series, 300 series, and 400 series. Due to harsh industrial environments, stainless steel items tend to corrode through galvanic corrosion, pitting corrosion, or other types of corrosion.

Types of fasteners

A bolt is a threaded fastener that is always used in conjunction with a nut. The external male thread is used for bolts, and the internal male thread is used for nuts. A bolt is made up of a head, a cylindrical body, and threads that run the length of it. Bolts have a flat head, which means there is no grove on the head. It usually has a design on its periphery that allows it to be driven by a wrench tool, and the same is true for the nut. Bolts and nuts are used for the following purposes:

Carriage bolts: – Carriage bolts have domed or countersunk heads with a square component under heat to keep the bolt from moving while tightening the nut.
Flange bolts: – It has a circular flange beneath the head that distributes loads evenly.
Plow bolts: – They have non-protruding heads and are intended for heavy-duty applications such as heavy equipment.
Hex-head bolts: – There are machine threads on all six sides.
Square-head bolts: – It has square heads, which make wrenches easier to grip.
