The Value Collection 42021 is a metric hex head cap screw designed for general mechanical fastening applications. It features an M5 x 0.80 thread profile with a 60 mm length under head and is manufactured from Grade 8.8 steel with a zinc-plated finish for corrosion resistance. The fastener is partially threaded and conforms to DIN 931 and ISO 4014 standards. An 8 mm hex drive makes it compatible with standard metric wrenches and sockets. This screw is commonly installed by millwrights, maintenance technicians, and assembly professionals working on machinery, equipment frames, and structural fixtures.
This fastener is suited for metric mechanical assemblies in both light industrial and commercial maintenance environments. The partial threading provides a smooth shank section useful in applications requiring a grip length or close-tolerance fit between mating components. Grade 8.8 steel provides a solid balance of tensile strength and ductility for medium-duty bolted joints. Sold in packages of 50 units with a minimum order quantity of 1 package.
Designed as a standard metric fastener for use in any application requiring an M5 x 0.80 partially threaded hex head cap screw per DIN 931 or ISO 4014 specifications.
Install using a metric wrench or socket sized for an 8 mm hex drive. Ensure mating threads are clean and free of debris before installation. Apply appropriate torque per the joint design requirements for Grade 8.8 fasteners. Do not exceed the rated mechanical grade by substituting this fastener in applications requiring higher-strength hardware such as Grade 10.9 or Grade 12.9.
