Value Collection -33680 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION -33680 is a partially threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assembly work. It features a 1/2-13 UNC thread size and a 7-inch length under the head, making it well suited for deep-reach clamping situations. The fastener is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a uniform matte appearance. Installation requires a 3/8-inch hex drive tool. Machinists, millwrights, and maintenance technicians typically install this type of fastener in equipment assemblies, fixtures, and structural mounts.

This socket cap screw is used in applications requiring a recessed drive head with a strong clamping load. The 1/2-13 UNC coarse thread profile allows for reliable engagement in standard tapped holes. Partial threading provides a smooth shank section that resists shear loads and aids in alignment during assembly. Common install scenarios include machine frames, jigs, tooling fixtures, and general mechanical assemblies in both production and maintenance settings. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.

Key Features

• 1/2-13 UNC coarse thread for engagement in standard tapped holes
• 7-inch length under head for deep-reach fastening applications
• Partially threaded shank resists shear loads and aids part alignment
• 3/8-inch hex socket drive for use with standard hex keys or socket drive tools
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides moderate corrosion resistance and reduces light reflection

Compatibility

Designed as a standard replacement or stock fastener for applications requiring 1/2-13 UNC partially threaded socket cap screws conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or socket drive. Ensure the receiving tapped hole is clean and dimensionally correct for 1/2-13 UNC thread engagement before installation. Do not use an impact driver without a torque-limiting attachment, as over-torquing alloy steel socket cap screws can cause thread stripping or fastener failure. Follow applicable equipment manufacturer torque specifications for the assembly being serviced.
