Holo-krome 72302 Hex Socket Cap Screw 3/4-10 Unc Alloy Steel

Product Description

The HOLO-KROME 72302 is a hex socket cap screw designed for high-strength fastening in mechanical assemblies, fixtures, and structural connections. It features a 3/4-10 UNC thread size with a 1-1/4 inch length under head and is fully threaded from head to tip. The drive is a 5/8 inch hex socket, requiring a standard hex key or Allen driver for installation. Constructed from alloy steel with a black oxide coating, this screw delivers corrosion resistance and a low-reflectance finish suited for industrial and commercial applications. It conforms to ASME B18.3 and ASTM A574 standards, confirming its suitability for demanding load and torque environments.

The HOLO-KROME 72302 is used in general industrial, HVAC equipment assembly, mechanical fabrication, and maintenance applications where a high-strength socket cap screw is required. Its fully threaded shank makes it well suited for shorter grip-length connections and through-hole or tapped-hole installations. Machinists, millwrights, pipefitters, and HVAC equipment technicians commonly specify this fastener when working with steel fixtures, frames, and equipment panels.

Key Features

• 3/4-10 UNC thread for reliable engagement in standard tapped holes
• Fully threaded shank provides maximum thread engagement over the full 1-1/4 inch length under head
• 5/8 inch hex socket drive accepts standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Conforms to ASME B18.3 dimensional standards for interchangeability

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw conforming to ASME B18.3, suitable for use in any tapped or through-hole application requiring this thread size and drive type.

Installation Notes

Installation is performed with a 5/8 inch hex key or T-handle driver; always verify that the receiving threads are clean and free of debris before fastening. De-energize or shut down any equipment being serviced before accessing fastener locations on live systems. Torque to values specified by the equipment manufacturer or applicable structural standards for 3/4-10 alloy steel fasteners. Inspect threads for damage or galling before re-use in critical joints.
