Holo-krome 60024 Flat Socket Cap Screw 6-32 X 3/8 in Alloy Steel

Product Description

The HOLO-KROME 60024 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a 5/64-inch hex socket drive, manufactured from alloy steel with a black oxide finish. The screw is fully threaded at a 6-32 UNC thread size and measures 3/8 inches in overall length. Hardness is rated at 39-44 HRC, making it suitable for demanding mechanical assemblies. It conforms to ASME B18.3 and ASTM F835 standards. Licensed mechanical assemblers, maintenance technicians, and industrial tradespeople typically install this fastener.

This flat socket cap screw is used in precision mechanical assemblies, fixture construction, enclosure fabrication, and general machine building where a low-profile, flush-mount fastener is required. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a common choice in tool and die, instrumentation, and light industrial applications. The 6-32 UNC thread is a standard coarse thread for small-diameter fasteners in both metal and machined plastic components.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 5/64-inch hex socket drive for precise torque application with standard Allen keys
• Fully threaded 6-32 UNC at 3/8 inches overall length
• Alloy steel construction with 39-44 HRC hardness rating
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any application requiring a 6-32 UNC fully threaded flat socket cap screw conforming to ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver. Ensure the mating hole is properly countersunk to 82 degrees to achieve full head seating and correct clamp load. De-energize and lock out any equipment before fastener replacement in live assemblies. Thread class 3A indicates a standard-fit tolerance — verify mating nut or tapped hole is class 3B for correct fit.
