Each screw measures 3\/16 inches in diameter by 2-1\/4 inches in length and features a Perma-Seal coating for corrosion resistance. The kit includes a drill bit sized for the application. With a 1-1\/2 inch embedment depth, this fastener delivers an ultimate tension load of 1,210 lb in 4,000 psi concrete and an ultimate shear load of 1,280 lb in 4,000 psi concrete. Electricians, plumbers, HVAC installers, and general contractors use these screws for securing conduit straps, pipe hangers, equipment brackets, and similar trade hardware to concrete substrates.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light to medium-duty anchoring applications in residential and commercial construction. Typical uses include attaching electrical boxes, strut channel, pipe clamps, and structural brackets directly to poured concrete or CMU block. The included drill bit ensures the pilot hole matches the thread profile of the tapper screw for a proper mechanical fit. The flat head profile sits flush with the work surface, making it a practical choice wherever a low-profile fastening point is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inches x 2-1\/4 inches tapper concrete screw — no anchor required\u003c\/li\u003e\n  \u003cli\u003ePerma-Seal coating provides corrosion resistance for long-term durability\u003c\/li\u003e\n  \u003cli\u003ePhillips flat head profile sits flush with the mounting surface\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch embedment depth with rated load values in 4,000 psi concrete\u003c\/li\u003e\n  \u003cli\u003eUltimate tension load: 1,210 lb; ultimate shear load: 1,280 lb\u003c\/li\u003e\n  \u003cli\u003eIncludes matching drill bit; packaged 100 screws per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for direct installation into poured concrete, concrete block, and masonry substrates where a 3\/16 inch diameter tapper-style concrete fastener is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed electricians, plumbers, HVAC technicians, or general contractors working to applicable building codes. Drill the pilot hole to the required depth using the included bit before driving the screw. Ensure the base material is free of debris and that embedment depth meets the 1-1\/2 inch minimum. Do not overtighten — strip-out will reduce holding values below rated loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Phillips Flat Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Tapper Concrete Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Perma-Seal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEmbedment Depth\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltimate Tension (4,000 psi Concrete)\u003c\/strong\u003e: 1,210 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltimate Shear (4,000 psi Concrete)\u003c\/strong\u003e: 1,280 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 screws per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Drill bit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.8 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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 375302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51563858395442,"sku":"375302","price":358.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/280e033aa88b7b8ef480a30ed3ec9fe7_e5e61270-b36e-4316-a389-3e74a2ae663a.jpg?v=1786505203","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-375302-concrete-screw-3-16x2-1-4-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
