Holo-krome 60050 Flat Socket Cap Screw 10-24 X 1 in

Product Description

The HOLO-KROME 60050 is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features an 82-degree flat head profile and a 1/8-inch hex socket drive, seating flush with or below the workpiece surface when installed in a properly machined countersink. The fastener is manufactured from alloy steel and carries a black oxide finish for moderate corrosion resistance. Thread size is 10-24 UNC with a 3A thread fit class, and the screw is fully threaded over its 1-inch overall length. Hardness is rated at 39-44 HRC, meeting ASME B18.3 and ASTM F835 standards.

This screw is used in mechanical assemblies, tool fixtures, machine guards, and equipment panels where a low-profile or flush head is required. The black oxide finish makes it a common choice for precision assemblies and tooling where minimal surface protrusion and a clean appearance matter. It is typically installed by machinists, millwrights, and maintenance technicians working on industrial equipment, structural fixtures, and fabricated steel components.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 1/8-inch hex socket drive for precise torque application with standard Allen keys or hex drivers
• Fully threaded 1-inch overall length for maximum thread engagement in thin materials
• Alloy steel construction rated at 39-44 HRC hardness
• Black oxide finish provides moderate corrosion and abrasion resistance
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-service fastener for applications requiring a 10-24 UNC fully threaded flat socket cap screw with an 82-degree head angle per ASME B18.3.

Installation Notes

Installation requires a properly machined 82-degree countersink to achieve a flush seating surface. Use a calibrated torque wrench with a 1/8-inch hex key or driver bit to prevent cam-out and fastener damage. Ensure mating threads are clean and free of debris before installation. A licensed machinist or qualified maintenance technician should verify thread engagement and torque requirements based on the specific joint design.
