Constructed from 18-8 stainless steel with an uncoated finish, this screw delivers solid corrosion resistance in both indoor and light outdoor environments. The Phillips drive allows for fast installation with standard hand or power tools. Thread engagement is measured under the head, and the UNC thread form ensures compatibility with standard inch-series tapped holes and nuts. Sold in a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in equipment panels, electrical enclosures, conduit fittings, HVAC cabinet assembly, and light structural fastening where stainless steel is specified for corrosion resistance. The truss head profile provides a wide, low-profile bearing surface that distributes clamping load across a larger area than a standard pan or round head, making it useful in sheet metal and thin-material applications common to the trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length measured under head for accurate stack-up calculations\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in damp or outdoor-adjacent environments\u003c\/li\u003e\n  \u003cli\u003eTruss head profile delivers a wide bearing surface on thin panels and sheet metal\u003c\/li\u003e\n  \u003cli\u003ePhillips drive compatible with standard No. 2 Phillips bits and screwdrivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating to crack, flake, or interfere with grounding contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-series machine screw suitable for use in any application calling for a 1\/4-20 truss head fastener in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is appropriate for electricians, HVAC technicians, plumbers, and general mechanical trades. De-energize all electrical equipment before fastening into or near live panels or enclosures per applicable NEC requirements. Use a No. 2 Phillips bit to avoid cam-out and head damage. Do not overtighten into tapped plastic or thin sheet metal — hand-snug plus a partial turn is typically sufficient to seat the truss head flush without distortion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Truss\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A210501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693878247730,"sku":"A210501","price":76.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ecdfed995c871fa1e18b385022dfdeb.jpg?v=1788318445","url":"https:\/\/voomisupply.com\/products\/value-collection-a210501-truss-head-machine-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
