It features a 5\/16-18 unified coarse thread and measures 1.5 inches under the head. The low-profile truss head provides a wide bearing surface, distributing clamping load across a larger area than a standard pan or round head. Manufactured from steel with a zinc finish for corrosion resistance, this screw meets ASME B18.6.3 and SAE J82 standards. It is suited for production assembly, MRO maintenance work, and structural panel fastening where a flush or low-profile fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light to medium-duty fastening applications across industrial maintenance, equipment assembly, and general construction. The truss head profile is commonly specified where clearance above the fastened surface is limited or where a wider bearing surface is needed to prevent pull-through in softer substrates. The slotted drive is compatible with standard flat-blade screwdrivers and slotted bits, making it accessible in field and shop environments alike. It is sold in multiples of 100 pieces per order, packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 unified coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eTruss head profile provides a wide, low-profile bearing surface\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with flat-blade screwdrivers and slotted power bits\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003e1.5-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production fastener for any application requiring a 5\/16-18 x 1.5-inch slotted truss head machine screw to ASME B18.6.3 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a flat-blade screwdriver or slotted bit sized to the screw slot to avoid cam-out and head damage. Ensure the mating tapped hole or nut is clean and properly threaded to 5\/16-18 UNC before driving. Do not overtorque — stop when the head seats firmly against the bearing surface. Power down or de-energize any equipment before fastening or removing screws on electrical or mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 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: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3124MST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711658295602,"sku":"3124MST","price":5973.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5e3312f3f356f25f34c9f3d37edd698.jpg?v=1788478256","url":"https:\/\/voomisupply.com\/products\/value-collection-3124mst-5-16-18-truss-head-slotted-machine-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
