A Short Article on Mechanical Fasteners

A mechanical fastener is a device that is used to mechanically join (or fasten or affixes) two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.

A welding joint or riveted joint can be termed as a permanent joint, which if required to be removed tends to damage or destruct both the joining components as well as the joint itself.



A washer is a thin plate (typically disk-shaped) with a hole (typically in the center) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Washers can also relieve friction, prevent corrosion or leakage, maintain tension and may serve as a spacer. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to permanent indentation after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces.

  • Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device. Locking washers is a type of spring washer.

Anchor Bolts & Screws

Anchor Bolt is a type of heavy-duty fastener that’s designed to allow objects to be attached to concrete surface. The bolt head is usually embedded in concrete leaving the threaded end exposed. The threaded end is attached to the connecting object with the help of nuts.

Anchor bolts are used widely for foundation purposes. They are used for anchoring and erecting structures and/or industrial equipment where durability and stability is required. Concrete forms, columns, foundations and pads are the most popular mediums where anchor bolts are used.


When selecting a product for industrial applications, it is important to consider a variety of factors. Few of them all listed below.
