Holo-krome 720002629 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The HOLO-KROME 720002629 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. This screw features a 1/2-13 UNC thread size with a 12-inch length under head and is partially threaded along its shank. The 3/8-inch hex drive socket accepts a standard hex key or Allen driver for installation. Manufactured from alloy steel with a black oxide finish, it delivers corrosion resistance and a clean, low-reflective appearance. Licensed tradespeople and industrial maintenance professionals rely on this type of fastener where tensile strength and dimensional precision are critical.

This screw is suited for use in heavy equipment, machine frames, jigs, fixtures, and structural bolting where a high-strength socket cap fastener is required. The 12-inch length under head makes it appropriate for applications requiring deep thread engagement or clamping through thick material sections. It conforms to ASME B18.3 and ASTM A574 standards, which are commonly specified in industrial and OEM engineering drawings for socket cap screws.

Key Features

• 1/2-13 UNC thread size for standard inch-series fastener compatibility
• 12-inch length under head accommodates thick material stacks or deep clamping depths
• Alloy steel construction meets ASTM A574 high-strength socket cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduced surface reflectivity
• 3/8-inch hex socket drive for use with standard hex keys or Allen drivers
• Partially threaded shank provides a bearing surface for precision alignment

Compatibility

Designed as a standard ASME B18.3 and ASTM A574 hex socket cap screw for use in applications specifying 1/2-13 UNC inch-series socket cap fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following applicable torque specifications from engineering drawings or fastener standards documentation. Ensure mating threads are clean and undamaged before installation. Use a properly sized 3/8-inch hex key or driver to avoid rounding the socket. Verify that the fastener grade and material are appropriate for the load, environment, and any applicable codes before installation.
