The ASTM or American Society for Testing and Materials is an organization that develops as well as publishes an international set of standards that is considered to be a voluntary consensus amongst producers, specifiers, fabricators, and users of steel mill products
Table of Content
The ASTM Fasteners Standards are reviewed each year and the status updated, even if there are no changes made to the standards.Generally, the most commonly used ASTM Fasteners Grades include austenitic stainless steel grades like 904L, 18-8, 200 series (like 201, 202, 205 & 216) or 300 series (like 301, 302, 303, 304, 305, 308, 310, 312, 314, 316, etc)
The Fastener ASTM Standards designation system for metals consists of a letter followed by an arbitrary but sequentially assigned number. For instance, the letter A has been assigned for ferrous materials. These designations are often applied to specific products, i.e. – the specification standard A548 is applied to a cold headed quality carbon steel wire for tapping as well as sheet metal screws.
The ASTM Stainless Steel Fasteners standards have an influence in the formation of specification, testing as well as evaluating the material in terms of the alloy’s mechanical, physical, dimensional, and metallurgical properties of the many forms of hardware fasteners available in the markets. These Fasteners ASTM Definition are used to mechanically join or fix other hardware objects together. These fasteners are available in many forms which include screws, washers, eyebolts, rivets, nuts, bolts, studs, nails, and threaded fasteners. These ASTM Stainless Steel Fasteners standards allow hardware product manufacturers, as well as the buyers or consumers of such products, to examine and to assess these fasteners in order to ensure their strength and quality are well maintained for safe utilization or application.
