The VALUE COLLECTION D39452 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assembly work. Built to Grade 8 steel specifications, this fastener delivers a high tensile strength suitable for demanding bolted connections. It measures 5/8-18 thread size with a 2-3/4 inch length under head and is finished with a zinc yellow dichromate coating that provides corrosion resistance and meets ASME B18.2.1 dimensional standards. Machinists, millwrights, and maintenance mechanics rely on this screw class for critical fastener applications.
This hex head cap screw is suited for general industrial assembly, equipment maintenance, and structural mechanical work where a UNF thread form and partial threading are required. The 5/8-18 UNF thread designation makes it appropriate for applications requiring finer thread engagement than a coarse-thread counterpart. Typical uses include machinery frames, jig and fixture assemblies, and heavy equipment repair. Sold individually with a minimum order quantity of 10 units per purchase.
Designed as a standard UNF hex head cap screw compatible with 5/8-18 threaded holes and nuts conforming to ASME B18.2.1 specifications in inch-system mechanical assemblies.
Installation should be performed by qualified mechanics or maintenance technicians using a properly sized hex wrench or socket. Always verify thread engagement depth and hole condition before driving the fastener. Do not exceed the rated torque for Grade 8 fasteners of this diameter as specified by applicable engineering standards. Inspect the mating threaded component for thread damage or contamination before assembly.
