Holo-krome 720000893 Hex Socket Cap Screw 10-24 Unc

Product Description

The HOLO-KROME 720000893 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and fabrication work. The screw features a 10-24 UNC thread size and a 3-inch length under head with partial threading. Drive engagement is through a 5/32-inch internal hex socket, which accepts a standard Allen wrench or hex key. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces surface glare. This fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for structural and load-bearing fastening tasks handled by machinists, maintenance technicians, and fabricators.

This screw is used in general industrial and mechanical assembly applications where a low-profile cap head and recessed hex drive are required. Typical installations include machine frames, fixtures, jigs, enclosures, and equipment housings. The partial threading allows for clamping force to develop in the unthreaded shank section, which is appropriate for applications requiring precise alignment or shear load resistance. It is also used in maintenance and repair operations across manufacturing and industrial facilities.

Key Features

• 10-24 UNC thread size for standard inch-series tapped holes
• 3-inch length under head with partial threading for shank clamping
• 5/32-inch hex socket drive compatible with standard Allen keys
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish for mild corrosion resistance in interior environments
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-specification hex socket cap screw for use in 10-24 UNC tapped holes in industrial machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen driver. Verify that the mating tapped hole meets 10-24 UNC thread specifications before installation. De-energize or lock out equipment before fastener removal or replacement in live machinery per applicable safety procedures. Avoid overtorquing, which can strip threads or compromise the fastener head socket.
