Holo-krome 72304 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The HOLO-KROME 72304 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features a 3/4-10 UNC thread size, a 1-1/2 inch length under head, and a 5/8 inch hex drive socket. Manufactured from alloy steel and finished with a black oxide coating, it meets ASME B18.3 and ASTM A574 standards. The fully threaded shank provides consistent thread engagement along the full length. This fastener is installed using a hex key or Allen driver and is a standard choice for machinists, millwrights, and maintenance mechanics working with bolted assemblies.

This cap screw fits a wide range of structural and mechanical bolting applications where a recessed hex drive is required. Fully threaded UNC fasteners in this size are common in equipment frames, motor mounts, jigs, fixtures, and general fabrication. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. Suitable for use in both shop and field environments where ASME B18.3 compliant fasteners are specified.

Key Features

• 3/4-10 UNC thread size for standard coarse-thread bolting applications
• 1-1/2 inch length under head, fully threaded shank
• 5/8 inch hex socket drive for torque-efficient installation
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide coating for mild corrosion resistance and low-reflectance finish
• Compliant with ASME B18.3 dimensional standards

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 3/4-10 UNC fully threaded fastener with a 5/8 inch hex drive.

Installation Notes

Installation requires a 5/8 inch hex key or Allen driver rated for the applied torque. Machinists, millwrights, and maintenance technicians typically install this fastener type. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread locker as required by the assembly specification; never substitute for proper torque verification per the applicable equipment service documentation.
