The anchor measures 1\/4 inch in diameter with a 1\/4 inch drill requirement and a 3\/4 inch overall length. It features a truss head profile and is manufactured from Zamac alloy with a zinc-plated finish for corrosion resistance. This style of anchor is driven into a pre-drilled hole using a standard hammer, expanding on impact to create a secure mechanical hold. It is commonly installed by electricians, plumbers, HVAC mechanics, and general contractors when securing conduit straps, pipe hangers, junction boxes, or light-duty equipment to concrete surfaces.\u003c\/p\u003e\u003cp\u003eThese anchors are suited for light-duty fastening applications in residential and commercial construction settings. The 1\/4 inch diameter and 3\/4 inch overall length make them appropriate for thin-section concrete and masonry installations where a shallow embedment depth is acceptable. Each package contains 100 anchors, making this a practical bulk-supply option for contractors who install multiple fasteners per job. The truss head provides a low-profile bearing surface that distributes load across a wider area compared to a standard flat head.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZamac alloy construction provides a balance of strength and corrosion resistance for indoor and protected masonry applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish adds a secondary layer of corrosion protection\u003c\/li\u003e\n\u003cli\u003eTruss head profile offers a low-profile, wide-bearing seating surface\u003c\/li\u003e\n\u003cli\u003eHammer-drive installation requires no specialty setting tool — a standard hammer is sufficient\u003c\/li\u003e\n\u003cli\u003e1\/4 inch drill size simplifies hole preparation with standard masonry bits\u003c\/li\u003e\n\u003cli\u003eSold in a 100-piece package for efficient job-site supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-supply hammer drive anchor for light-duty fastening into concrete, block, and masonry substrates requiring a 1\/4 inch diameter anchor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by drilling a 1\/4 inch hole to the required embedment depth using a hammer drill and carbide-tipped masonry bit, then inserting the anchor and driving it flush with a standard hammer. Always clear drill dust from the hole before setting the anchor to ensure full mechanical engagement. Verify that the base material is sound and free of cracks before installation, as fractured concrete reduces holding capacity. Follow applicable building codes and the fastener manufacturer load tables when calculating allowable loads for the intended application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnchor Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired Drill Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Truss\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnchor Material\u003c\/strong\u003e: Zamac Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162101\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 31970\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701055783218,"sku":"31970","price":36.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbecddbc4c4f438313a6b1d56f034b25.jpg?v=1788397546","url":"https:\/\/voomisupply.com\/products\/value-collection-31970-hammer-drive-concrete-anchor-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
