The VALUE COLLECTION MPKP44020 is a fully threaded hex head cap screw designed for high-strength fastening applications across mechanical, structural, and trade assembly work. It features a 5/16-18 UNC thread size and a 3/4-inch length under head, manufactured from Grade 8 steel with a zinc-plated finish for corrosion resistance. The screw meets ASTM A354 BD standards, indicating tensile strength suitable for demanding load-bearing connections. This fastener is a staple for HVAC equipment mounting, electrical panel brackets, plumbing fixture attachment, and general mechanical assembly where a high-strength inch-series fastener is required.
This screw is suited for residential and light commercial trade applications where Grade 8 strength and a zinc-plated finish are specified. Common install scenarios include equipment frames, motor mounts, junction box hardware, and bracket assemblies. The fully threaded shank provides consistent thread engagement across the full length of the fastener, making it appropriate for thin-material and close-tolerance applications. Sold in a package quantity of 50 units, this item is practical for both single-job use and shop stock replenishment.
Designed as a standard inch-series hex head cap screw compatible with any application specifying a 5/16-18 UNC fully threaded fastener in Grade 8 steel.
Installation requires a standard hex wrench or socket sized for a 5/16-18 fastener. Always verify thread engagement depth and mating nut or tapped hole rating before final torque. Power down or de-energize any equipment before fastening near electrical or mechanical components. Follow applicable codes including NEC or IFGC as relevant to the assembly being serviced.
