The VALUE COLLECTION 88548219 is a 5/16-18 x 1-1/2 inch hex head cap screw designed for general fastening applications across mechanical, structural, and trade installations. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener offers reliable corrosion resistance for both indoor and light outdoor service environments. The UNC (Unified National Coarse) thread form and partially threaded shank make it well-suited for clamping applications where thread engagement is needed at the bearing surface. HVAC technicians, plumbers, electricians, and general contractors regularly use Grade 5 hex cap screws for equipment mounting, panel attachment, and mechanical assembly work.
This screw is appropriate for residential and light commercial applications where a standard inch-series coarse-thread fastener is required. The 5/16-18 thread size is one of the most common in trade work, fitting a wide range of equipment brackets, junction boxes, pipe hangers, and structural supports. The zinc coating provides a functional barrier against rust in typical service conditions without adding significant dimensional variation. Packaged in quantities of 50, this item suits both job-site stock and shop inventory needs.
Designed as a standard inch-series UNC hex head cap screw suitable for general mechanical fastening applications across HVAC, plumbing, electrical, and structural trades wherever a 5/16-18 thread form is specified.
Install using a standard hex wrench or socket driver sized for a 5/16-18 hex head cap screw. Ensure the mating hole or nut matches the UNC 5/16-18 thread standard before installation. Power down or de-energize any equipment being fastened before beginning work. Do not exceed the design load for the Grade 5 rating when used in structural or load-bearing applications.
