Value Collection 011271P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011271P is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 3/8-16 UNC thread size with a 3-inch length under head and is partially threaded along the shank. The 5/16-inch hex drive accepts a standard hex key or Allen wrench for installation. Constructed from alloy steel with a black oxide finish coating, the 011271P delivers corrosion resistance and meets ASME/ANSI B18.3 and ASTM A574 standards for socket cap screws. This fastener is suited for applications requiring precise tensile strength and clean, recessed drive installation.

This screw is commonly used in machine tool assemblies, jigs and fixtures, equipment frames, and general fabrication work where a flush or low-profile fastener head is required. The 3/8-16 UNC coarse thread pattern provides reliable engagement in tapped steel, aluminum, and similar materials. The partial threading keeps the unthreaded shank section available for alignment or shear-load applications. It is sold as a single piece with a minimum order quantity of 50 units.

Key Features

• 3/8-16 UNC coarse thread for broad tap compatibility
• 3-inch length under head with partial threading for shear-load and alignment use
• 5/16-inch hex socket drive for hex key or Allen wrench installation
• Alloy steel construction with black oxide coating for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards
• Minimum order quantity of 50 pieces

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any 3/8-16 UNC tapped bore requiring a socket drive fastener in industrial and mechanical assemblies.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen wrench; use a torque wrench rated for the fastener grade when required by the assembly specification. Ensure the mating tapped hole is clean and free of debris before threading. Follow applicable ASME or equipment manufacturer torque guidelines for 3/8-16 alloy steel socket cap screws. Always inspect threads for damage before reuse.
