Holo-krome 60062 Flat Socket Cap Screw 1/4-20 X 3/4 in

Product Description

The HOLO-KROME 60062 is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features an 82-degree flat head with a 5/32-inch hex socket drive, a 1/4-20 UNC thread, and a fully threaded 3/4-inch overall length. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM F835 standards and is hardened to 39-44 HRC. Licensed machinists, millwrights, and mechanical contractors install this fastener where a low-profile, countersunk head is required in structural or machine components.

This screw is suited for precision machine assembly, tooling fixtures, jigs, and industrial equipment requiring a flush surface finish after installation. The 3A thread fit class provides a close tolerance engagement appropriate for load-bearing and vibration-prone environments. The black oxide finish offers mild corrosion resistance in indoor or lightly protected applications. It is sold in multiples of 100, making it appropriate for production assembly lines or maintenance stock replenishment.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a clean, low-profile surface
• 5/32-inch hex socket drive accepts standard Allen or hex key tooling
• Alloy steel construction hardened to 39-44 HRC for high tensile and shear strength
• Fully threaded 3/4-inch shank maximizes thread engagement across the full length
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock flat socket cap screw for machinery, fixtures, and equipment requiring a 1/4-20 UNC countersunk fastener with an 82-degree head angle.

Installation Notes

Installation requires a properly sized countersunk hole machined to an 82-degree included angle to achieve full head seating. Use a calibrated hex key or T-handle driver sized to 5/32 inches to avoid rounding the socket. Power down or de-energize any equipment before fastener replacement or removal. Follow applicable mechanical and structural codes for torque requirements based on joint design and material.
