A fastener is a device that mechanically joins parts together. Many pins are used in industry and manufacturing to assemble components that would be difficult or impossible to build with the human hand alone. The materials used in these fasteners are chosen for their physical, mechanical, and chemical properties. The most common materials include metals, plastics, and composites. This article will explore four factors that affect fasteners material specification.
Mechanical Requirements
Fasteners, also known as bolts, are mechanical devices used to join or fix two or more objects together by connecting them with a fastening element. Fasteners can be categorized according to the mechanical requirements of their fastening elements. The most popular and commonly used type of fastener is the threaded fastener.
Environmental Conditions
Most fasteners are subjected to different environmental conditions with the usage of these fasteners. Fasteners are under extreme pressure, and they have to withstand rust, dust, and other harmful particles. The material specification of fasteners changes as per the environment they will be used in.
Surface Treatment
The surface treatment done affects the fasteners material specification. For example, when the fastener must be resistant to corrosion, then stainless steel should be used. The different surface treatments applied to the fasteners include plating, painting, and finishing.
The Size of Fastening Needed
When picking a fastener for a given application, one of the most important decisions is to determine the fastener’s size. This decision has a huge impact on material choice.
