Item Description


Socket cap screws are high-strength tension fasteners designed for clamping assemblies and are commonly used in tool and die fixture applications. Socket screws, also known as Allen head screws, are available in several head styles and materials. Used in many applications, socket screws are reliable and durable. Choose stainless steel screws when you need corrosion resistance. Length is measured from under the head. Screws have a Class 3A thread fit, a minimum tensile strength of 70,000 psi, and a minimum Rockwell hardness of B70.

Common Fastener Label Definitions

"Stainless Steel" - With the addition of 12% chromium to iron, stainless steel is formed. The chromium protects the iron against most corrosion or red colored rust; thus the term "stainless steel". The ability of stainless to form a thin layer of protection on its outside surface, called a "passive film", is its most important characteristic in preventing corrosion.

"18-8" - 300 series stainless steel having approximately (not exactly) 18% chromium and 8% nickel. The term "18-8" is used interchangeably to characterize fasteners made of 302,302HQ,303,304,384, XM7, and other variables of these grades with close chemical compositions. There is little overall difference in corrosion resistance among the 18-8 types, but slight differences in chemical composition do make certain grades more resistant than others against particular chemicals or atmospheres.

Austentic - Refers to 300 series stainless, the most popular of the stainless alloys accounting for 85%-90% of stainless fasteners soldNamed for sir Robert Williams Austen, an English metallurgist, austentic stainless is a crystal structure formed by heating steel, chromium, and nickel to a high temperature where it forms the characteristics of 300 series stainless steel.

Tensile Strength - A common measure to compare the strength of a fastener. It is the load needed to pull the fastener apart.

Yield - The resistance to a load pulling on the middle of a fastener until the fastener shows permanent deformation.
