Value Collection 011387PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011387PR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size and a 6.5-inch length under head, with a 3/8-inch hex drive for use with a hex key or Allen driver. Constructed from alloy steel with a black oxide coating, this fastener delivers reliable clamping force and moderate corrosion resistance in demanding environments. Licensed mechanics, millwrights, pipefitters, and maintenance technicians are the typical installers.

This cap screw is suited for medium-to-heavy-duty fastening tasks where a flush or recessed drive head is required. The partial threading allows for precise clamping on thicker material stacks without thread engagement through the full grip length. Common applications include machine bases, fixtures, tooling plates, and structural frames where controlled torque and alloy steel strength are required. It is sold in multiples of 10 per order with a package quantity of 1.

Key Features

• 1/2-13 UNC thread size provides coarse-thread engagement suitable for general industrial fastening
• 6.5-inch length under head accommodates thicker material stacks and deep joint assemblies
• Partially threaded shank delivers a clean grip zone and prevents thread galling in clearance holes
• Alloy steel construction offers high tensile strength for demanding load applications
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance
• 3/8-inch hex drive accepts standard hex keys and socket drivers

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for industrial equipment, fixtures, and assemblies requiring a 1/2-13 UNC partially threaded hex socket cap screw meeting ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a 3/8-inch hex key or socket driver. Ensure mating threaded holes are clean and free of debris before installation. Apply thread lubricant or anti-seize compound where required by the application. Follow equipment manufacturer torque specifications and applicable ASME standards for fastener tightening procedures.
