Value Collection R52001340 Machine Screw 5/16-18 Unc 1 in

Product Description

The VALUE COLLECTION R52001340 is a slotted truss head machine screw designed for general fastening applications across industrial, mechanical, and trade service work. It features a 5/16-18 UNC thread form with a 1-inch length under head, providing a broad, low-profile truss head that distributes clamping load over a wider bearing surface than a standard pan or round head. The screw is manufactured from Grade J82 steel with a zinc-plated finish for basic corrosion resistance in indoor and light-duty environments. It ships without a washer. This fastener is a standard catalog item used by HVAC technicians, electricians, plumbers, and general mechanical contractors for equipment assembly and field repairs.

This machine screw is suited for residential and light commercial applications where a coarse-thread 5/16-18 UNC fastener is required. Common uses include securing sheet metal assemblies, mounting brackets, electrical enclosures, and mechanical equipment panels. The truss head profile is particularly useful where a flat bearing surface is needed without the added thickness of a separate washer. Sold individually per package, with a minimum order quantity of 100 pieces.

Installation Notes

Install using a flat-blade screwdriver or appropriate bit driver sized for the slotted head. Verify the mating hole or nut is threaded to 5/16-18 UNC before installation. De-energize and lock out all electrical or mechanical equipment before servicing any fastened assembly. Do not overtighten, as doing so may strip the slotted drive or damage the mating thread.
