Holo-krome 60030 Flat Socket Cap Screw 6-32 X 3/4 in Alloy Steel

Product Description

The HOLO-KROME 60030 is a flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. It features an 82-degree flat head with a 5/64-inch hex socket drive, allowing installation with standard hex keys in tight or recessed locations. The screw is fully threaded in a 6-32 UNC thread form at an overall length of 3/4 inches. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM F835 fastener standards. Hardness is rated at 39-44 HRC, making it suitable for moderate-to-high strength fastening tasks. This screw is commonly installed by mechanical and electrical technicians and maintenance trades.

This flat socket cap screw is used in panel assemblies, enclosures, machinery, and equipment where a low-profile flush head is required to avoid interference with mating surfaces or covers. The 6-32 UNC thread size is widely used in light mechanical and electrical assemblies, including control enclosures, HVAC equipment panels, and instrumentation hardware. The black oxide finish provides mild corrosion resistance and reduces surface glare in finished assemblies. This screw is sold in minimum order quantities of 100 pieces per order.

Key Features

• Meets ASME B18.3 and ASTM F835 standards

Compatibility

Designed as a standard 6-32 UNC flat socket cap screw suitable for use in any application requiring an ASME B18.3 or ASTM F835 compliant countersunk socket fastener in alloy steel.

Installation Notes

Installation requires a properly sized 5/64-inch hex key or driver bit. The mating workpiece must be drilled and countersunk to an 82-degree angle to seat the flat head flush. Ensure threads in the receiving material are clean and free of debris before driving. Apply appropriate thread preload for the assembly; do not exceed the torque range appropriate for 6-32 alloy steel fasteners as specified in the assembly documentation.
