Holo-krome 730003080 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The HOLO-KROME 730003080 is a hex socket cap screw designed for high-strength bolted assemblies in mechanical, HVAC, and industrial applications. It features a 3/4-16 UNF thread, a 2-inch length under head, and a 5/8-inch hex drive socket. The screw is fully threaded and machined from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces surface reflectivity. It meets ASME B18.3 and ASTM A574 standards, confirming dimensional and mechanical-property compliance. Maintenance technicians, millwrights, and mechanical contractors use this fastener where a recessed drive and high clamp load are required.

This screw suits applications calling for fine-thread engagement in hard materials or thin-walled sections, where the 3/4-16 UNF pitch delivers greater tensile strength and finer adjustment compared to coarse-thread equivalents. Typical install scenarios include equipment frames, compressor mounts, pump housings, and structural brackets in commercial HVAC and industrial machinery. The black oxide alloy steel construction handles moderate-heat environments and repeated torque cycles without galling when properly lubricated.

Key Features

• 3/4-16 UNF fine thread for high tensile load and precise adjustment
• 2-inch length under head, fully threaded for maximum thread engagement
• 5/8-inch hex socket drive for standard Allen or hex key tooling
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish reduces friction and provides light corrosion protection
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw suitable for tapped holes and threaded inserts requiring a 3/4-16 UNF fine-thread fastener in alloy steel construction.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench and the appropriate 5/8-inch hex key or driver bit. Apply a compatible thread lubricant or anti-seize compound to prevent galling and ensure accurate torque loading. Verify thread condition in the mating tapped hole before installation. Follow equipment manufacturer torque specifications and applicable industry standards for the assembly being serviced.
