Holo-krome 730003360 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The HOLO-KROME 730003360 is a hex socket cap screw designed for high-strength bolted assemblies requiring precise thread engagement and a low-profile head. It carries a 3/4-16 UNF thread specification, an 8-inch length under head, and is driven by a 5/8-inch hex socket. The alloy steel construction is finished with a black oxide coating, providing moderate corrosion resistance and reducing light reflection in field installations. This screw is partially threaded, which improves shear strength along the unthreaded shank and is standard practice for structural fastening in mechanical and industrial applications. Licensed machinists, millwrights, and mechanical contractors are the typical installers.

This socket cap screw is suited for high-load mechanical assemblies in industrial, commercial, and heavy equipment applications. The 3/4-16 UNF fine-thread configuration provides greater tensile strength and finer adjustment control compared to coarse-thread equivalents, making it appropriate for precision machinery, hydraulic components, structural steel connections, and equipment frames where vibration resistance matters. The partially threaded shank is particularly well matched to applications where the fastener passes through a clearance hole before engaging a tapped hole.

Key Features

• 3/4-16 UNF fine thread for higher tensile strength and vibration resistance
• 8-inch length under head with partial threading for structural shank strength
• 5/8-inch hex socket drive for high-torque installation with standard socket tooling
• Alloy steel construction meets ASME B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and a non-reflective surface

Compatibility

Designed as an OEM-style or replacement fastener for industrial machinery, structural assemblies, and mechanical equipment requiring a 3/4-16 UNF partially threaded hex socket cap screw conforming to ASME B18.3 and ASTM A574.

Installation Notes

Installation should be performed by qualified mechanical or millwright trades using a calibrated torque wrench and the appropriate 5/8-inch hex socket driver. Always verify that the mating tapped hole thread class and material are compatible before installation. De-energize, depressurize, or otherwise isolate the equipment before fastener removal or replacement. Do not substitute lubricants or thread-locking compounds without confirming compatibility with the base material and finish coating.
