The hardened high-low thread cuts its own path into masonry as the screw is driven, creating a secure mechanical hold. Installation is a straightforward two-step process: drill a pilot hole, then drive the screw. The screw can be removed and re-inserted into the same hole, making it useful for applications that require periodic access. Each pack contains 25 screws measuring 3\/16 inch in diameter by 1-3\/4 inches in length.\u003c\/p\u003e\u003cp\u003eThe HILLMAN 41554 is suited for light-duty masonry fastening in residential and light commercial construction. Typical applications include window installations, interior handrails, metal door frames, storm shutters, interior lighting fixture mounting, thresholds, and screened enclosures. The hex washer head style allows for driving with a standard nut driver or hex-head bit, which is common in both new construction and retrofit work on concrete block and brick masonry substrates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-low thread design cuts directly into masonry — no anchor required\u003c\/li\u003e\n\u003cli\u003eRemovable and re-insertable in the same pilot hole\u003c\/li\u003e\n\u003cli\u003eSlotted hex washer head compatible with nut driver or hex bit\u003c\/li\u003e\n\u003cli\u003eSuitable for concrete, brick, and block substrates\u003c\/li\u003e\n\u003cli\u003eTwo-step installation: drill pilot hole, then drive screw\u003c\/li\u003e\n\u003cli\u003eSold in a 25-count clamshell pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in concrete, brick, and block masonry substrates in applications such as window installations, interior handrails, metal door frames, storm shutters, interior lighting fixtures, thresholds, and screened enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires drilling a correctly sized pilot hole into the masonry substrate before driving the screw. Use a carbide-tipped masonry bit sized to the manufacturer recommendation for 3\/16 inch concrete screws. Drive with a hex-head bit or nut driver at controlled speed to avoid stripping the masonry thread. Follow applicable local building codes when fastening structural or load-bearing components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Slotted Hex Washer Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: High-Low Masonry Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate Compatibility\u003c\/strong\u003e: Concrete, Brick, Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.293 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00008236186406\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41554\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51346201215282,"sku":"41554","price":15.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549186.jpg?v=1782073712","url":"https:\/\/voomisupply.com\/products\/hillman-41554-concrete-screw-3-16-x-1-3-4-in-25-count","provider":"Voomi Supply","version":"1.0","type":"link"}
