Value Collection C89573 Hex Head Cap Screw 7/16-14 Grade 8

Product Description

The Value Collection C89573 is a Grade 8 steel hex head cap screw with a 7/16-14 UNC thread and a 5.5-inch length under the head. Partially threaded along the shank, it delivers high tensile strength suited to heavy-duty fastening applications in mechanical, structural, and industrial assemblies. The zinc yellow dichromate finish provides corrosion resistance while meeting the dimensional and mechanical requirements of ASME B18.2.1 and SAE J429. This screw is installed by millwrights, maintenance technicians, pipefitters, and general contractors wherever a high-strength imperial fastener is required.

This cap screw is used in industrial machinery, structural steel connections, heavy equipment maintenance, and fabrication work. The partial thread pattern provides a smooth shank bearing surface that resists lateral shear loads, making it appropriate for applications involving close-tolerance clearance holes and bolted joint assemblies. It ships in a package quantity of 10 and is sold in multiples of 1, making it suitable for both single-repair and small-batch use.

Installation Notes

Installation should be performed by a qualified technician familiar with bolted joint procedures and applicable torque specifications for Grade 8 fasteners. Always use a calibrated torque wrench and apply fastener torque values per the relevant engineering specification or equipment OEM guidance — do not estimate by feel. Inspect the mating threads for damage or contamination before installation. Use appropriate thread lubricant or thread locker only when specified by the assembly drawing or maintenance manual.
