Holo-krome 60052 Flat Socket Cap Screw 10-24 X 1-1/4 in

Product Description

The HOLO-KROME 60052 is a flat socket cap screw designed for applications that require a flush or countersunk fastener profile. It features an 82-degree flat head with a 1/8-inch hex socket drive and is fully threaded along its 1-1/4-inch overall length at a 10-24 UNC thread size. Manufactured from alloy steel with a black oxide finish, it carries a hardness rating of 39-44 HRC and meets Thread Fit Class 3A. This fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors in precision assemblies where a low-profile head is required.

This screw is suited for light industrial, manufacturing, and mechanical assembly applications where a countersunk hex-socket fastener is specified. The 82-degree flat head seats flush in standard countersunk holes, making it appropriate for machine frames, fixtures, jigs, enclosures, and similar structural or mechanical assemblies. The black oxide finish provides a moderate level of corrosion resistance in dry or mildly humid indoor environments.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 1/8-inch hex socket drive for precise torque application with standard hex keys
• Fully threaded 10-24 UNC, Thread Fit Class 3A for consistent engagement
• Alloy steel construction rated 39-44 HRC for high-strength fastening
• Black oxide finish for moderate corrosion resistance in indoor environments
• Conforms to ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style or replacement flat socket cap screw for machinery, fixtures, and mechanical assemblies requiring a 10-24 UNC fully threaded countersunk fastener with an 82-degree flat head profile.

Installation Notes

Install using a calibrated 1/8-inch hex key or hex socket driver. Countersink the mating hole to 82 degrees for proper flush seating. Power down and de-energize any equipment before fastener service or replacement. Follow applicable ASME and facility torque guidelines for 10-24 alloy steel fasteners.
