It features a slotted drive and a low-profile, wide-bearing truss head that distributes clamping load across a larger surface area than a standard pan or round head. The screw is manufactured from steel with a zinc finish for basic corrosion resistance and conforms to ASME B18.6.3 and SAE J82 standards. Thread size is 3\/8-16 (coarse thread) with a length under head of 2.5 inches. This fastener is installed by maintenance technicians, millwrights, electricians, and HVAC service professionals in light structural and equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for through-bolting panels, brackets, electrical enclosures, equipment frames, and ductwork supports where a wide bearing surface is needed to prevent pull-through. The coarse 3\/8-16 thread provides reliable thread engagement in tapped steel and aluminum components. It is commonly found in commercial HVAC unit assembly, electrical panel mounting, and general industrial maintenance scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTruss head profile provides a wide, low-profile bearing surface to distribute clamping load\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 coarse thread for strong engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head accommodates thicker stack-ups and panel assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc finish offers basic corrosion resistance for indoor and light-duty applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction with Material Grade J82 for consistent mechanical properties\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series machine screw for use in any application requiring a 3\/8-16 coarse-thread truss head slotted fastener per ASME B18.6.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a flat-blade screwdriver sized to the slotted drive to avoid cam-out and head damage. Ensure the mating tapped hole or nut is rated for 3\/8-16 coarse thread before installation. De-energize any electrical equipment before fastening enclosures or panels per applicable NEC guidelines. Do not over-torque; thread stripping is a risk in softer base materials such as aluminum or plastic.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3 and SAE J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0773 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: 3740MST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710657790258,"sku":"3740MST","price":1129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a332fc9a31810d392fb5d8099083ad6_5c8cfc1c-d4ea-4af9-a5af-8b1634318a60.jpg?v=1788469179","url":"https:\/\/voomisupply.com\/products\/value-collection-3740mst-truss-head-machine-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
