Value Collection 011149P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011149P is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies, fixtures, and fabricated components. It features a 1/4-20 UNC thread and a 3/4-inch length under head with full threading along the entire shank. The 3/16-inch hex drive socket accepts a standard hex key or Allen wrench for installation. Constructed from alloy steel with a black oxide finish, this fastener provides corrosion resistance and a clean, low-reflectance appearance suited to precision applications. Licensed tradespeople, machinists, and maintenance technicians working with close-tolerance assemblies will find it meets ASME/ANSI B18.3 and ASTM A574 standards.

This screw is appropriate for use in light industrial equipment, machinery maintenance, tooling fixtures, and general mechanical fabrication where a compact, high-strength socket head fastener is required. The unified coarse thread pitch is widely compatible with standard tapped holes in steel, aluminum, and similar materials. It is sold individually but carries a minimum order quantity of 100 pieces, making it suited for shop stock, maintenance kits, or production use. Residential and commercial trades requiring reliable threaded fasteners in confined spaces will find the recessed socket drive particularly useful where bolt-head clearance is limited.

Key Features

• 1/4-20 UNC thread for compatibility with standard unified coarse tapped holes
• Fully threaded 3/4-inch length under head for maximum thread engagement
• 3/16-inch hex socket drive accepts standard hex keys and Allen-style drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduced surface reflectance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 1/4-20 UNC hex socket cap screw with a 3/4-inch length under head and fully threaded shank.

Installation Notes

Installation is performed using a 3/16-inch hex key or Allen driver; ensure the driver is fully seated in the socket to avoid cam-out and fastener damage. Torque to the assembly specification supplied by the equipment manufacturer or engineering drawing. Follow applicable ASME or ANSI fastener standards when specifying or replacing fasteners in structural or pressure-bearing assemblies. Inspect threads in the mating tapped hole for damage or contamination before installation to ensure full thread engagement.
