Manufactured from C1022 steel with a 1,000-hour Dacro coating for corrosion resistance, this fastener delivers reliable holding power in demanding environments. The unslotted indented hex washer head with shoulder provides consistent seating and high torque transfer. An EPDM bonded washer helps create a weather-resistant seal at the fastener head. The hardened Type 3 point enables clean penetration without pre-drilling on compatible materials.\u003c\/p\u003e\u003cp\u003eThese lap screws are suited for light-gauge steel framing assemblies, metal building components, and structural panel connections where a self-drilling, corrosion-resistant fastener is required. They are commonly installed by framing contractors, steel building erectors, and skilled tradespeople working on commercial or residential steel construction projects. Each pack contains 250 screws, making it practical for production-rate installation work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eC1022 steel construction with hardened body for strength and durability\u003c\/li\u003e\n\u003cli\u003e1,000-hour Dacro coating provides long-term corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSelf-tapping with hardened Type 3 point for no-pilot-hole installation\u003c\/li\u003e\n\u003cli\u003eUnslotted indented hex washer head with shoulder for controlled seating and torque\u003c\/li\u003e\n\u003cli\u003eEPDM bonded washer creates a weather-resistant seal at the fastener head\u003c\/li\u003e\n\u003cli\u003e250-count pack for high-volume framing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fastener for light-gauge steel lap framing applications requiring a 14 x 7\/8 inch self-tapping galvanized screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by framing contractors or steel construction tradespeople using a hex-head power driver or impact driver sized for the hex washer head. Ensure the substrate materials are clamped or held securely before driving to maintain joint alignment. Follow applicable building codes and manufacturer structural guidelines for fastener spacing and edge distances. Do not overtorque, as this can compromise the EPDM washer seal and reduce holding strength.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 x 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: C1022 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Dacro, 1,000-hour corrosion resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Unslotted Indented Hex Washer Head with Shoulder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher\u003c\/strong\u003e: EPDM Bonded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Self-Tapping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.935 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACORN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SW-L1478G250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51343938650418,"sku":"SW-L1478G250","price":49.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547092.jpg?v=1782025833","url":"https:\/\/voomisupply.com\/products\/acorn-sw-l1478g250-lap-framing-screw-14x7-8-in-250-ct","provider":"Voomi Supply","version":"1.0","type":"link"}
