Holo-krome 72262 Hex Socket Cap Screw 1/2-13 Unc 8 in

Product Description

The HOLO-KROME 72262 is a hex socket cap screw designed for high-strength bolted connections in industrial, mechanical, and trade applications. It features a 1/2-13 UNC thread size with a 3/8-inch hex drive and an 8-inch length under the head. The fastener is partially threaded and manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces light reflection on exposed hardware. Machinists, millwrights, and maintenance technicians install this type of fastener where a flush or low-profile head and high clamp load are required.

This screw is suited for use in machinery frames, structural assemblies, jigs and fixtures, and mechanical equipment requiring a reliable UNC fastener in a larger diameter and extended length. The 1/2-13 UNC thread pitch is a coarse-thread standard, which allows faster assembly and better resistance to cross-threading in field conditions. The black oxide finish is appropriate for interior or lightly protected environments. This fastener is sold in a minimum order quantity of 10 units per order, with individual package quantity of 1.

Key Features

• 1/2-13 UNC coarse thread for fast engagement and reduced cross-threading risk
• 8-inch length under head accommodates thick or stacked material assemblies
• Partially threaded shank provides a bearing surface for shear load applications
• Alloy steel construction delivers high tensile and proof load strength
• Black oxide coating offers mild corrosion protection and low-glare appearance
• Meets ASME B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw conforming to ASME B18.3 and ASTM A574, suitable for use in any application requiring a partially threaded alloy steel socket cap screw of this thread size and length.

Installation Notes

Installation requires a 3/8-inch hex key or socket drive. De-energize and lock out all equipment before fastener removal or replacement in mechanical assemblies. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer. Torque to the value specified by the equipment or structural design documents, not the fastener manufacturer alone.
