Value Collection 011375P Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011375P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, machinery, and structural connections. The fastener features a 1/2-13 UNC thread size, a 3-1/2 inch length under head, and accepts a 3/8 inch hex drive. Constructed from alloy steel with a black oxide finish, this screw delivers solid corrosion resistance and a clean, low-reflectance appearance. It is partially threaded, making it suited for clamping applications where a grip length is needed. Machinists, millwrights, and maintenance technicians commonly install this type of fastener across industrial and commercial settings.

This hex socket cap screw is used in a wide range of applications including machine frames, jigs and fixtures, motor mounts, and equipment housings. The 1/2-13 UNC coarse thread is one of the most common thread pitches in North American industrial and OEM manufacturing environments. The partially threaded shank provides a smooth bearing surface through the clamped material, which is standard practice for bolted joint integrity in precision assemblies. This fastener is sold in multiples of 25.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 3-1/2 inch length under head with partial threading for proper grip length
• 3/8 inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Minimum order quantity of 25 units per order

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 compliant hex socket cap screw for use in any application requiring a 1/2-13 UNC partially threaded fastener with a 3/8 inch hex drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Always verify the tapped hole thread specification matches 1/2-13 UNC before installation. Black oxide fasteners are not intended for outdoor or high-humidity environments without supplemental lubrication or corrosion protection. Follow applicable machinery maintenance standards and lock out or tag out all energy sources before servicing any assembly that uses these fasteners.
