Holo-krome 780140031 Hex Socket Cap Screw 6-32 Unc

Product Description

The HOLO-KROME 780140031 is a hex socket cap screw designed for precision fastening applications requiring corrosion resistance and consistent clamping force. This fastener features a 6-32 UNC thread, a 5/16-inch length under head, and a 7/64-inch hex drive. It is fully threaded along its entire shank length. Constructed from 18-8 stainless steel with a bright, uncoated finish, it meets ASME B18.3 and ASTM F837 standards. Machinists, maintenance technicians, and trade professionals install these screws where a low-profile socket head and stainless corrosion resistance are required in tight or recessed assemblies.

This screw is suited for light-duty mechanical assemblies, electrical enclosures, HVAC equipment panels, and plumbing fixture hardware where a 6-32 UNC thread form is specified. The socket drive allows installation with a standard hex key in confined spaces where a slotted or Phillips driver would not seat properly. The fully threaded shank maximizes thread engagement across the full 5/16-inch working length, which is critical in thin-material applications.

Key Features

• 6-32 UNC thread for standard light-duty fastening applications
• Fully threaded shank provides maximum thread engagement over the 5/16-inch length
• 7/64-inch hex socket drive allows use in recessed or tight-clearance locations
• 18-8 stainless steel construction resists corrosion in wet or humid environments
• Bright, uncoated finish — no coating thickness to account for in close-tolerance fits
• Meets ASME B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard 6-32 UNC hex socket cap screw suitable for use in any application specifying an ASME B18.3 socket head cap screw in 18-8 stainless steel with a 5/16-inch length under head.

Installation Notes

Install with a 7/64-inch hex key or allen driver; use of a calibrated torque driver is recommended for assemblies with defined clamp-load requirements. Ensure mating threads are clean and free of debris before installation to prevent galling, which is common with stainless steel fasteners. Apply an anti-seize compound to the threads when required to reduce the risk of galling during installation or future removal. Power down or de-energize any equipment before accessing fasteners on live panels or enclosures.
