This screw type is a standard choice for securing brackets, straps, conduit supports, equipment pads, and structural components to concrete surfaces. The hex head drive style allows for fast installation with a standard nut driver or hex-head bit, reducing install time on repetitive fastening tasks. Sold individually, with 100 screws packed per jar for job-site organization and easy counting.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in residential and light commercial applications where concrete anchoring is required. Typical install scenarios include securing HVAC equipment bases, plumbing hangers, electrical conduit straps, and support brackets directly to poured concrete or block walls. The penetrator thread design cuts directly into the base material without requiring a separate anchor insert, making it a one-step fastening solution for trade professionals working in concrete environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch diameter by 3-1\/4-inch length for medium-depth concrete fastening\u003c\/li\u003e\n\u003cli\u003eHex head drive for fast installation with standard nut drivers or impact drivers\u003c\/li\u003e\n\u003cli\u003ePenetrator thread design cuts directly into concrete without a separate anchor\u003c\/li\u003e\n\u003cli\u003e100 screws per jar for organized job-site storage and easy inventory count\u003c\/li\u003e\n\u003cli\u003eSuitable for securing equipment, hangers, straps, and brackets to concrete and masonry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct concrete fastening screw for use in standard 1\/4-inch pre-drilled concrete or masonry pilot holes in residential and light commercial construction and mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, electricians, or general contractors requiring concrete fastening. Always pre-drill a correctly sized pilot hole in the concrete substrate per the fastener manufacturer and applicable local building code requirements. Ensure the substrate is free of debris before driving the screw. Do not overdrive, as stripping the thread engagement in concrete will compromise holding strength.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Penetrator Concrete Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Jar\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662352093682\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STEWART FASTENER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J2728\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51346037997874,"sku":"J2728","price":28.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552167.jpg?v=1782069379","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-j2728-hex-head-concrete-screw-100-per-jar","provider":"Voomi Supply","version":"1.0","type":"link"}
