Value Collection MP72246 Hex Socket Cap Screw 1/2-13 Unc 5 Pack

Product Description

The VALUE COLLECTION MP72246 is a 1/2-13 UNC hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and construction assemblies. Made from alloy steel with a black oxide finish, this partially threaded cap screw delivers corrosion resistance and reduces galling during installation. The 3/8-inch hex drive accepts a standard hex key or Allen driver. At 3.5 inches length under head, it suits medium-depth through-bolt and tapped-hole applications. Installers working in HVAC equipment assemblies, pump mounts, mechanical frames, and structural brackets will find this screw a reliable choice. Sold in a 5-piece package, it conforms to ASME B18.3 and ASTM A574 standards.

This cap screw is suited for use in industrial maintenance, equipment fabrication, and mechanical assembly where a recessed hex drive is preferred over external-drive fasteners. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for bolted joints where shank engagement through a clearance hole is required. Typical installers include millwrights, pipefitters, HVAC mechanics, and general maintenance technicians working with tapped steel or ductile iron components.

Key Features

• 1/2-13 UNC thread form for compatibility with standard inch-series tapped holes
• 3.5 inches length under head suits medium to deep fastening applications
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partial threading allows shank to bear shear loads in clearance-hole assemblies
• 3/8-inch hex drive size accepts standard hex keys and T-handle drivers

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any tapped 1/2-13 UNC through-hole or blind-hole application requiring a high-strength alloy steel fastener.

Installation Notes

Installation requires a 3/8-inch hex key or Allen-head driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before servicing fastened assemblies. Do not substitute thread lubricants or anti-seize compounds unless specified by the equipment manufacturer, as doing so affects clamp load calculations.
