Value Collection 581215PR Hex Socket Cap Screw 6-32 Unc

Product Description

The VALUE COLLECTION 581215PR is a partially threaded hex socket cap screw designed for secure fastening in tight-clearance applications. It carries a 6-32 UNC thread size and measures 1-3/4 inches under the head, driven by a 7/64-inch hex key. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and modest corrosion resistance in indoor and controlled-environment assemblies. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for precision mechanical and industrial applications where dimensional consistency matters.

This screw is suited for light machine assemblies, electronic enclosures, fixtures, and equipment panels where a low-profile socket drive head is required. The partial threading allows for clearance-hole clamping, pulling mating parts firmly together without threading the entire shank through the assembly. Electricians, millwrights, and mechanical assemblers commonly use this fastener when working with tapped aluminum or steel components requiring a clean, finished appearance.

Key Features

• 6-32 UNC thread for compatibility with standard inch-series tapped holes
• 1-3/4 inch length under head suits deeper-reach fastening needs
• 7/64-inch hex drive allows use of standard Allen keys and hex bit drivers
• Partial threading supports clearance-hole clamping applications
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides a clean appearance and mild surface protection

Compatibility

Designed as a standard ASME/ANSI B18.3-compliant hex socket cap screw for use in any application requiring a 6-32 UNC partially threaded fastener with a 7/64-inch hex drive.

Installation Notes

Install using a calibrated 7/64-inch hex key or socket bit driver; do not overtighten, as alloy steel cap screws in small diameters are susceptible to torque-induced shear. Ensure the receiving tapped hole is clean and properly formed to the 6-32 UNC specification before driving. Black oxide finish offers limited corrosion resistance and is best suited for dry or lightly oiled indoor environments.
