Holo-krome 73014 Hex Socket Cap Screw 1-72 Unf 1/4 in

Product Description

The HOLO-KROME 73014 is a hex socket cap screw designed for precision fastening in tight-clearance applications. It carries a 1-72 UNF thread - one of the finer unified thread pitches used in instrumentation, electronics, and small mechanical assemblies. The drive is a 1/16 inch hex socket, requiring an Allen wrench or hex key of the same size. The screw is fully threaded along its 1/4 inch length under head, manufactured from alloy steel, and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. Installation requires a torque tool or hand driver suited for small-diameter fasteners.

This screw is suited for applications where fine thread engagement and compact head profile are required. Common use cases include instrument panels, electronic enclosures, optical equipment, small mechanical assemblies, and precision machine components. The 1-72 UNF thread pitch is standard in many OEM and MRO environments where miniature fastening is specified. The black oxide finish is appropriate for interior or low-moisture environments. Sold in multiples of 10 per order.

Key Features

• 1-72 UNF thread - fine pitch for secure engagement in thin or soft materials
• Fully threaded 1/4 inch length under head maximizes thread engagement across the full shank
• 1/16 inch hex socket drive for use with standard Allen keys or hex drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish reduces surface reflectivity and offers light rust inhibition in dry conditions
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as an OEM-style and MRO replacement hex socket cap screw for applications specifying a 1-72 UNF fully threaded fastener with a 1/16 inch hex drive, conforming to ASME B18.3 and ASTM A574 standards.

Installation Notes

Installation is performed with a 1/16 inch hex key or ball-end driver. Verify thread engagement depth in the mating material before applying torque - the short length under head leaves minimal margin for shallow tapped holes. Black oxide fasteners are not rated for outdoor or high-humidity environments without additional lubrication or sealant. Always confirm thread fit by hand-starting the screw before driving to prevent cross-threading in fine-pitch tapped holes.
