Value Collection 33667 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 33667 is a partially threaded hex socket cap screw engineered for demanding mechanical and structural fastening applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and a consistent clamping load. The 1/2-13 UNC thread pattern pairs with a 2-1/4 inch length under head, providing ample thread engagement for secure connections. Installation requires a 3/8 inch hex (Allen) key drive, making it compatible with standard socket tooling used in industrial maintenance, machine assembly, and equipment fabrication environments.

This cap screw is suited for general industrial, manufacturing, and MRO applications where a high-strength alloy steel fastener is required. The black oxide coating reduces surface friction during installation and offers mild corrosion protection in light-duty environmental conditions. Its coarse UNC thread form is well-matched to through-hole and tapped-hole assemblies in steel, cast iron, and similar ferrous base materials. Tradespeople and maintenance technicians working on machinery, fixtures, frames, or structural steel components will find this a reliable standard-duty fastener.

Key Features

• 1/2-13 UNC coarse thread for reliable engagement in tapped ferrous assemblies
• 2-1/4 inch length under head with partial threading for controlled clamping
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduced surface friction
• 3/8 inch hex socket drive compatible with standard Allen keys and socket driver tooling

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in tapped holes and through-bolt assemblies in industrial machinery, structural frames, and equipment fabrication applications.

Installation Notes

Installation is performed using a 3/8 inch hex key or socket driver. Ensure the tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or thread-locking compound per the equipment manufacturer's requirements. Do not exceed the rated fastener torque specification for the base material to avoid thread stripping or fastener failure.
