Value Collection 011259P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011259P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and trade installations. It features a 3/8-16 UNC thread size, a 1-1/2 inch length under head, and a 5/16 inch hex drive. Constructed from alloy steel with a black oxide finish, this fully threaded fastener delivers solid clamping force and corrosion resistance in demanding environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for engineers and tradespeople who require dimensional and mechanical compliance.

This screw is suited for use in residential and commercial mechanical systems where a compact, recessed-drive fastener is required. The hex socket drive allows installation in confined spaces where a standard hex head wrench cannot reach. Typical applications include equipment brackets, motor mounts, pump housings, enclosure panels, and structural assembly work across HVAC, plumbing, and general industrial trades. The black oxide coating reduces surface friction and provides mild corrosion protection in dry or low-moisture environments.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped holes
• Fully threaded along the 1-1/2 inch length under head for maximum thread engagement
• 5/16 inch hex socket drive allows use in tight or recessed clearances
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 3/8-16 UNC fully threaded fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation requires a 5/16 inch hex key or Allen-type socket driver. Verify the mating tapped hole conforms to 3/8-16 UNC thread standards before driving. Ensure the fastener is fully seated and that appropriate thread depth is available in the base material to achieve rated clamping force. Black oxide fasteners are not intended as a primary corrosion barrier in wet or outdoor environments without additional protective treatment.
