Holo-krome 68004 Low Socket Cap Screw 8-32 X 1/2 in Alloy Steel

Product Description

The HOLO-KROME 68004 is a low socket cap screw designed for applications where a reduced head height is required and clearance is limited. Sized at 8-32 UNC x 1/2 inch, it is fully threaded under the head and driven with a 5/64 inch hex key. The head height measures 0.0850 inches, making it well suited for tight assemblies where a standard socket cap head would interfere with adjacent components. Manufactured from alloy steel with a black oxide finish, the fastener meets ASME B18.3 and ASTM A574 standards. Licensed mechanics, millwrights, and maintenance technicians working on precision equipment are the primary installers.

This fastener is used in industrial, mechanical, and electronic assembly applications where coarse-thread 8-32 fasteners are specified and vertical clearance is constrained. The low-profile head design is commonly found in panel assemblies, fixture plates, tooling jigs, and enclosure builds. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or instrumentation environments. It is packaged individually with a minimum order quantity of 100 pieces.

Key Features

• Low socket cap head profile at 0.0850 inches head height for clearance-critical installations
• 8-32 UNC coarse thread, fully threaded under head
• 5/64 inch hex socket drive (0.0781 inch decimal)
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Conforms to ASME B18.3 dimensional standard

Compatibility

Designed as an OEM-style replacement or direct-specification fastener for any application requiring an 8-32 UNC low socket cap screw per ASME B18.3 in alloy steel with black oxide finish.

Installation Notes

Installation requires a 5/64 inch hex key or matching hex bit driver. Ensure the mating threaded hole is clean and free of debris before installation. Apply appropriate torque per ASME or fastener manufacturer guidelines for 8-32 alloy steel cap screws. Do not overtorque, as low socket cap heads have a reduced drive engagement depth compared to standard socket cap screws.
