Holo-krome 61014 Flat Socket Cap Screw 10-32 1-1/2 in Alloy Steel

Product Description

The HOLO-KROME 61014 is a flat socket cap screw designed for precision fastening applications where a flush or countersunk installation is required. It features an 82-degree flat head with a 1/8-inch hex socket drive and is manufactured from alloy steel with a black oxide finish. The screw measures 10-32 UNF thread size at 1-1/2 inches overall length and is partially threaded. Hardness is rated at 39 to 44 HRC, making it suitable for high-strength assemblies. It conforms to ASME B18.3 and ASTM F835 standards. This fastener is typically installed by machinists, maintenance technicians, and industrial assembly professionals.

This screw is used in applications requiring a low-profile, countersunk head seating flush with or below the surface of the mating material. Common install scenarios include machine frames, fixtures, tooling plates, and equipment panels where a protruding head would interfere with clearance or movement. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision environments. The 3A thread fit class ensures close tolerances suitable for tight-tolerance assemblies.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 1/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction rated at 39 to 44 HRC hardness for high-strength applications
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Partially threaded shank per ASME B18.3 and ASTM F835 standards
• 3A thread fit class for close-tolerance UNF thread engagement

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with 10-32 UNF countersunk holes machined to ASME B18.3 specifications in metal assemblies, fixtures, and equipment panels.

Installation Notes

Installation requires a 1/8-inch hex key or Allen driver; use of a calibrated torque driver is recommended for consistent clamp load in precision assemblies. Ensure the mating countersink is machined to 82 degrees to match the head angle before installation. Power down and de-energize any equipment before fastener replacement or removal on live assemblies. Follow applicable machine safety standards and torque guidelines published in ASME B18.3 for the thread size and material combination in use.
