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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for reliable engagement in standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eTruss head profile provides a wide, low-profile bearing surface without a washer\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eGrade J82 steel construction for solid mechanical strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection for indoor service environments\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head suits standard panel and bracket fastening tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC coarse-thread machine screw suitable for use in any application requiring a truss head fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall 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.
