Value Collection 592257PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 592257PR is a partially threaded hex socket cap screw designed for secure fastening in mechanical, industrial, and trade applications. It features a 1/4-20 UNC thread size and measures 2.25 inches in length under the head. The 3/16-inch hex drive accepts a standard Allen key or hex bit driver. Constructed from 18-8 austenitic stainless steel with a bright uncoated finish, this fastener resists corrosion and maintains strength in wet or chemically active environments. It meets ASME/ANSI B18.3 and ASTM F837 standards.

This cap screw is suited for light to medium-duty fastening tasks across HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies. The 1/4-20 UNC coarse thread pattern is widely used in North American equipment and machinery. Partial threading allows for clamping force over a defined grip length, making it appropriate for applications where thread engagement needs to be controlled. It is typically installed by maintenance technicians, millwrights, or trade professionals requiring a corrosion-resistant fastener in stainless steel.
