At 1.25 inches in length, this smooth-shank bright nail is sized for driving through standard underlayment sheet goods into floor decking without over-penetrating. The box unit contains 12 pounds of nails, giving flooring contractors and carpenters a workable bulk quantity for larger jobs. Bright finish nails are intended for interior dry applications where corrosion resistance is not a primary requirement.\u003c\/p\u003e\n\u003cp\u003eThese underlayment nails are used in residential and light commercial flooring work, typically driven by hand or pneumatic nailer into plywood, OSB, or hardboard underlayment over wood subfloor systems. The 3D designation indicates the penny size, which corresponds to the 1.25-inch length standard for thin underlayment panels. Flooring installers, finish carpenters, and general contractors commonly stock this nail size when installing resilient flooring, tile backer, or laminate underlayment substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25-inch length suitable for underlayment-to-subfloor fastening without blow-through\u003c\/li\u003e\n  \u003cli\u003e3D penny size — standard sizing for thin sheet underlayment applications\u003c\/li\u003e\n  \u003cli\u003eBright finish for interior dry-condition installations\u003c\/li\u003e\n  \u003cli\u003eSold by the box at 12 pounds per unit for bulk job-site use\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 12 units per box for stocking and resale\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3D bright underlayment nail for use with plywood, OSB, and hardboard underlayment panels in interior wood-frame floor assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUnderlayment nails are installed by flooring contractors and carpenters using a hammer or pneumatic finish nailer rated for the appropriate nail gauge and length. Fasten panels per the underlayment manufacturer's nailing schedule, typically starting from the center and working outward to prevent buckling. Ensure the subfloor is clean, flat, and dry before fastening underlayment. Bright nails are not rated for exterior or moisture-exposed applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePenny Size\u003c\/strong\u003e: 3D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: BX (Box)\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: 461380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51558415499570,"sku":"461380","price":58.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b36580d1832b9191cc62ea42162169.jpg?v=1786411775","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-461380-underlayment-nail-1-25in-3d-bright","provider":"Voomi Supply","version":"1.0","type":"link"}
