The HOLO-KROME 730003340 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and trade installations. It features a 3/4-16 UNF thread size, a 7-inch length under head, and a 5/8-inch hex drive. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection in service environments. It meets ASME B18.3 and ASTM A574 standards, confirming compliance with dimensional and mechanical property requirements for socket cap screws.
This screw is suited for use in machinery, structural brackets, hydraulic components, and other assemblies where a recessed drive and high clamp load are required. The partial thread design is appropriate for applications that require a smooth shank for alignment or shear loading. Machinists, millwrights, pipefitters, and maintenance technicians commonly install this type of fastener in both production and field-repair contexts across industrial and commercial settings.
Designed as a standard ASME B18.3 hex socket cap screw suitable for use wherever a 3/4-16 UNF partially threaded socket cap screw is specified in mechanical or industrial assemblies.
Install using a calibrated torque wrench with the appropriate 5/8-inch hex key or socket bit. De-energize or depressurize any system before fastener replacement or removal. Inspect mating threads for damage or contamination before installation, and apply a thread lubricant or anti-seize compound appropriate for the service environment if specified by the assembly documentation. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards.
