Holo-krome 78040 Hex Socket Cap Screw 10-24 Unc Stainless

Product Description

The HOLO-KROME 78040 is a hex socket cap screw designed for secure fastening in applications that demand corrosion resistance and dimensional consistency. Sized at 10-24 UNC with a 5/8 inch length under head, this fastener is fully threaded and driven by a 5/32 inch hex socket key. Constructed from 18-8 stainless steel with a bright uncoated finish, it meets ASME B18.3 and ASTM F837 standards. It is appropriate for use by maintenance technicians, millwrights, equipment assemblers, and trade professionals who require reliable threaded fasteners in corrosive or high-humidity environments.

This cap screw is suited for light mechanical assemblies, enclosure mounting, equipment panels, and structural connections where a low-profile socket head and full thread engagement are required. The 10-24 UNC thread pattern is common in general industrial and commercial equipment, HVAC hardware, electrical enclosures, and plumbing fixtures. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor installations where moisture or chemical exposure is a factor.

Key Features

• 10-24 UNC thread size with full threading along the 5/8 inch length under head
• 5/32 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• Bright uncoated finish maintains dimensional accuracy for tight-tolerance applications
• Meets ASME B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard 10-24 UNC hex socket cap screw for use in any application or assembly that accepts this thread size and socket head profile per ASME B18.3.

Installation Notes

Installation is performed with a 5/32 inch hex key or hex socket bit driver. Ensure the mating threaded hole or nut is clean and free of debris before installation. When installing stainless steel fasteners, apply an appropriate anti-seize compound to reduce the risk of galling. Follow applicable equipment manufacturer torque guidelines for the assembly being serviced.
