Value Collection D39145 5/8-11 X 1 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION D39145 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assembly work. Built to Grade 8 steel specification, this fastener delivers a high tensile and proof load rating suited to demanding bolted joints. The 5/8-11 UNC thread profile mates with standard inch-series nuts and tapped holes. A zinc yellow dichromate finish provides corrosion resistance and visual identification as a Grade 8 fastener. Manufactured to ASME B18.2.1 dimensional standards, it offers consistent head geometry and thread engagement for reliable torque-tension performance. Machinists, maintenance mechanics, and structural tradespeople install this type of fastener across a broad range of equipment and fabrication work.

This screw is suited for bolted connections in heavy equipment, structural steel assemblies, and industrial machinery where high clamp load and shear strength are required. The 5/8-11 UNC thread size is one of the most common heavy fastener sizes used in North American trade applications. The fully threaded shank maximizes thread engagement for use in short-grip applications. Sold individually, with a minimum order quantity of 25 pieces per order.

Key Features

Compatibility

Designed as an OEM-style and general-replacement fastener for any application requiring a 5/8-11 UNC hex head cap screw with Grade 8 strength and a 1 inch grip length.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, and structural tradespeople using standard hex sockets or open-end wrenches. Always consult applicable torque specifications for Grade 8 fasteners at this diameter before final tightening. Ensure mating threads are clean and free of debris before assembly. Follow relevant industry standards and equipment manufacturer guidelines when replacing structural or load-bearing fasteners.
