Holo-krome 720003364 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The HOLO-KROME 720003364 is a partially threaded hex socket cap screw engineered for high-strength fastening in industrial and mechanical assemblies. It carries a 3/4-10 UNC thread size and measures 11 inches in length under the head, making it suited for applications that require deep thread engagement and a long grip length. The 5/8-inch hex drive accepts a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, it resists corrosion in moderate environments while maintaining the tensile strength required for demanding structural connections. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This cap screw is used in heavy equipment, machinery frames, structural fixtures, and mechanical assemblies where a recessed drive and high clamp load are required. The partial threading provides a smooth shank bearing area, which helps control shear loads and maintain precise alignment in close-tolerance bored holes. It is appropriate for both new fabrication work and field maintenance applications across industrial, commercial, and trade settings.

Key Features

• 3/4-10 UNC thread for standard coarse-thread compatibility in alloy steel applications
• 11-inch length under head accommodates thick material stacks and deep fastening applications
• Partially threaded shank provides a bearing surface for shear load resistance and alignment
• 5/8-inch hex socket drive accepts standard Allen keys and hex-drive power tools
• Black oxide coating provides mild corrosion resistance and reduces light reflection on exposed fasteners
• Meets ASME B18.3 and ASTM A574 standards for socket cap screws

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for industrial machinery, structural assemblies, and mechanical fixtures requiring 3/4-10 UNC coarse-thread fasteners with a 5/8-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, and industrial maintenance technicians using a calibrated torque wrench with a 5/8-inch hex bit. De-energize and lock out all equipment before servicing any assembly this fastener secures. Inspect the mating threaded hole for damage or debris before installation. Apply thread lubricant or anti-seize compound as required by the assembly specification to achieve accurate clamp load from torque values specified in the engineering documentation for the host assembly.
