Value Collection MP33662 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION MP33662 is a hex socket cap screw engineered for high-strength fastening in mechanical, industrial, and trade assembly applications. Sized at 1/2-13 UNC with a 1-inch length under head and fully threaded shank, this fastener is driven with a 3/8-inch hex key. Constructed from alloy steel with a black oxide coating, it delivers the tensile strength required for demanding bolted connections while the black oxide finish provides moderate corrosion resistance and reduces light glare in exposed assemblies. Licensed trades and industrial maintenance technicians are the primary installers.

This screw is suited for general mechanical assembly, machine building, equipment maintenance, and structural fastening tasks where a recessed hex drive is required. The 1/2-13 UNC coarse thread pattern offers reliable thread engagement in steel tapped holes and is a widely used thread standard across American manufacturing and fabrication environments. The fully threaded configuration ensures maximum thread engagement along the entire shank length, making it appropriate for through-hole and shorter-reach tapped-hole applications.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard American tapped holes
• Fully threaded shank maximizes thread engagement in short-reach applications
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 strength standards
• Black oxide coating provides moderate corrosion resistance and low-reflectance finish
• 3/8-inch hex socket drive for use with standard hex keys and Allen drivers

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 or ASTM A574 compliant fastener in an American coarse-thread tapped hole.

Installation Notes

Install with a 3/8-inch hex key or Allen driver; ensure mating threads are clean and free of debris before driving. De-energize and lock out any equipment before replacing fasteners on live machinery, following applicable OSHA lockout/tagout procedures. Verify thread engagement depth in the tapped hole meets minimum standards for the load application. Do not use impact tools unless the fastener and joint design are rated for that installation method.
