Holo-krome 720002625 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The HOLO-KROME 720002625 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features a 1/2-13 UNC thread size and measures 10 inches in length under the head, making it well suited for deep-clearance bolting conditions. The screw is partially threaded and driven with a 3/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and meets the dimensional and mechanical requirements of ASME B18.3 and ASTM A574. Installation is performed by maintenance technicians, millwrights, and mechanical contractors.

This cap screw is appropriate for use in structural assemblies, machine frames, equipment mounting, and other applications that require a recessed-drive, high-strength fastener. The partial threading accommodates clamping loads across unthreaded shank sections, which is common in flanged joints and precision machine assemblies. The black oxide coating provides light corrosion protection suitable for indoor and dry-environment applications.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard inch-series tapped holes
• 10-inch length under head for deep-clearance and long-reach bolting applications
• Partially threaded shank supports accurate clamping and joint alignment
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides light corrosion resistance and reduces light reflection
• 3/8-inch hex drive for use with standard hex keys and socket drivers

Compatibility

Designed as an OEM-style replacement or direct-install hex socket cap screw for standard 1/2-13 UNC tapped assemblies in industrial and mechanical applications.

Installation Notes

Installation is typically performed by millwrights, mechanical technicians, or maintenance contractors using a 3/8-inch hex key or socket driver. De-energize and lock out all equipment before fastener installation or removal in accordance with applicable OSHA LOTO procedures. Thread engagement and torque requirements should be confirmed against the assembly drawing or engineering specification for the application. Do not exceed the rated mechanical properties of the fastener by over-torquing.
