Value Collection 015369PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015369PR is a partially threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 2-3/4-inch length under head and a 3/8-inch hex drive socket. Constructed from alloy steel with a black oxide finish, this fastener provides solid tensile strength and moderate corrosion resistance in dry or lightly oiled environments. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a specification-compliant choice for precision assemblies requiring traceable fastener performance.

This screw is suited for machine frames, tooling fixtures, jigs, brackets, and mechanical enclosures where a recessed drive head and reliable clamping force are required. The partial thread design allows for shouldered clamping, which is useful when joining two components with controlled grip length. Installers in HVAC equipment assembly, electrical panel fabrication, pump and compressor maintenance, and general industrial service will find this fastener appropriate for a wide range of bolted connections requiring a standard UNC thread pattern.

Key Features

• 1/2-13 UNC thread form for compatibility with standard inch-series tapped holes
• Partially threaded shank provides controlled grip length and shoulder clamping capability
• Alloy steel construction delivers high tensile and shear strength
• Black oxide coating offers mild corrosion resistance and reduces light reflection
• 3/8-inch hex socket drive accepts standard hex keys and socket drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 1/2-13 UNC partially threaded hex socket cap screw with a 2-3/4-inch length under head.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a calibrated hex key or socket driver sized to 3/8 inch. Ensure the mating tapped hole is clean, properly sized to 1/2-13 UNC, and free of debris before threading. Apply a thread lubricant or anti-seize compound appropriate for the base material when required by the assembly specification. Power down or de-energize any equipment before accessing fastener locations on live mechanical or electrical assemblies.
