Introduction and Fasteners Specification
Introduction to Fastener
A fastener is a hardware device that mechanically joins 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. Welding is an example of creating permanent joints. There are three major steel fasteners used in industries: stainless steel, carbon steel, and alloy steel. The major grade used in stainless steel fasteners: 200 series, 300 series, and 400 series.

Titanium, aluminum, and various alloys are also common materials of construction for metal fasteners. In many cases, special coatings or plating may be applied to metal fasteners to improve their performance characteristics by, for example, enhancing corrosion resistance.
Common coatings/platings include zinc, chrome, and hot dip galvanizing ASTM Fastener Specification ASTM`s fastener standards are instrumental in specifying, testing, and evaluating the material, dimensional, mechanical, and metallurgical properties of the various forms of hardware fasteners.
These fasteners are used to mechanically join or affix other hardware objects together, and come in many forms which include rivets, nuts, bolts, studs, screws, washers, eyebolts, nails, and threaded fasteners. These fastener standards allow hardware product manufacturers, as well as the end-users of such products, to examine and assess fasteners to ensure their strength and quality towards safe utilization.
The American Society for Testing and Materials is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.
