Value Collection 015401PR Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 015401PR is a fully threaded hex socket cap screw designed for high-strength fastening applications across mechanical, industrial, and trade environments. Made from alloy steel with a black oxide finish, this fastener provides corrosion resistance and reduced light reflection in service conditions where appearance and durability both matter. The 1/2-20 UNF thread size and 2-inch length under head make it well suited for precision fastening tasks requiring fine-thread engagement. Drive is a 3/8-inch hex socket, compatible with standard Allen keys and hex drive tools. Installation is performed by mechanics, millwrights, pipefitters, and general maintenance professionals.

This screw is used in applications requiring a fine-thread, high-strength cap screw in ferrous or structural assemblies. Fully threaded along its 2-inch length under head, it provides maximum thread engagement for secure clamping force. The black oxide coating is appropriate for indoor or protected environments where mild corrosion resistance is acceptable. Conformance to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards makes this fastener suitable for use in engineered assemblies with specified fastener grades.

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1/2-20 UNF fully threaded alloy steel fastener with a 3/8-inch hex drive.

Installation Notes

Installation requires a 3/8-inch hex key or socket driver; do not use an undersized driver as it will damage the socket. Torque to the value specified by the assembly engineer or applicable fastener standard for the joint material and lubrication condition. Ensure mating threads are clean and free of debris before installation. Always de-energize or lock out equipment before performing fastener service on powered machinery.
