Value Collection A997070 Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION A997070 is a 3/8-16 button socket cap screw designed for fastening applications that require a low-profile head and high tensile strength. Made from alloy steel with a black oxide finish, this screw measures 2.5 inches in length under the head and is fully threaded with a right-hand UNC thread. The hex socket drive accepts a 7/32 inch hex key for installation. With a hardness rating of 36-43 HRC and a thread fit class of 3A, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. It is sold in packs of 10.

This button socket cap screw is suited for mechanical assemblies, fixtures, and structural connections where a rounded, low-profile head is preferred over a standard cap screw. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a common choice in machine building, equipment fabrication, and maintenance applications. Licensed tradespeople and maintenance technicians working in fabrication shops, industrial facilities, or field service environments will encounter this fastener type regularly.

Compatibility

Designed as a standard 3/8-16 UNC button socket cap screw for use in any threaded hole or nut conforming to UNC 3/8-16 thread specifications.

Installation Notes

Install using a 7/32 inch hex key or T-handle driver; do not use an undersized driver as it will damage the socket. Ensure the mating threaded hole or nut is clean and free of debris before installation. Follow applicable torque guidelines from ANSI/ASME B18.3 for the thread size and material being fastened. Alloy steel fasteners should not be used in environments with sustained exposure to moisture without additional corrosion protection beyond the black oxide finish.
