Holo-krome 60116 Flat Socket Cap Screw 7/16-14 X 3/4 in

Product Description

The HOLO-KROME 60116 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 1/4-inch hex socket and is fully threaded along its 3/4-inch overall length. The 7/16-14 UNC thread form meets ASME B18.3 and ASTM F835 standards. Manufactured from alloy steel with a black oxide finish, it delivers a hardness rating of 39-44 HRC, making it suitable for high-strength fastening tasks. Machinists, millwrights, and mechanical contractors typically install this fastener in metal fabrication, machinery assembly, and structural fixturing applications.

This flat socket cap screw is used in applications where a low-profile, countersunk head is required to sit flush with or below a mating surface. Common install scenarios include machine frames, jigs, fixtures, and equipment enclosures where protruding fastener heads are not acceptable. The fully threaded shank and UNC thread form make it compatible with standard tapped holes in steel, aluminum, and other ferrous and non-ferrous materials. The black oxide finish provides mild corrosion resistance in interior or controlled-environment installations.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 1/4-inch hex socket drive for standard Allen key or hex bit installation
• Fully threaded 7/16-14 UNC shank along the full 3/4-inch length
• Alloy steel construction with 39-44 HRC hardness for high-strength applications
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and general-use replacement flat socket cap screw for standard 7/16-14 UNC tapped holes in machinery, fixtures, and structural assemblies conforming to ASME B18.3 specifications.

Installation Notes

Install with a calibrated 1/4-inch hex key or hex socket bit driver. Ensure the mating countersink is machined to an 82-degree included angle for full head seating. Power down or de-energize any equipment before fastener removal or installation on live assemblies. Follow applicable machine safety and torque guidelines per the equipment manufacturer or relevant ASME standards.
