It measures 1 inch in length under the head and is manufactured from Grade 18-8 stainless steel, providing solid corrosion resistance in exposed or moisture-prone installations. The T15 Torx drive reduces cam-out during high-torque driving, making it well suited for production assembly and field service work. A Type A point allows this screw to self-tap into pre-punched or drilled sheet metal without a separate nut. Electricians, HVAC technicians, and sheet metal workers rely on this fastener for enclosure assembly, ductwork, and equipment panel work.\u003c\/p\u003e\u003cp\u003eThis screw is appropriate for light-gauge sheet metal applications found in residential and commercial HVAC equipment, electrical enclosures, and general mechanical assemblies. The button head profile sits low and distributes clamping load across a wider bearing surface than a flat head, which helps prevent pull-through in thinner gauges. It is sold individually but requires a minimum order quantity of 10 units, making it practical for restocking field kits or bench stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction provides corrosion resistance for indoor and moderately humid environments\u003c\/li\u003e\n\u003cli\u003eT15 Torx drive reduces cam-out compared to Phillips or slotted drives\u003c\/li\u003e\n\u003cli\u003eType A self-tapping point threads into pre-punched sheet metal without a nut or insert\u003c\/li\u003e\n\u003cli\u003eButton head profile offers a low-profile, wide-bearing-surface finish\u003c\/li\u003e\n\u003cli\u003eInch measurement system with 1 inch length measured under the head\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-system sheet metal fastener suitable for light-gauge sheet metal assemblies, HVAC equipment panels, electrical enclosures, and similar thin-material applications where a Size 8 self-tapping screw with a Torx drive is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a T15 Torx bit driver or a T15 Torx socket. Ensure the receiving material is pre-punched or drilled to the appropriate pilot hole diameter for a Size 8 Type A screw before driving. Do not overdrive — button head screws in thin sheet metal can strip the tapped hole if torque is excessive. Stainless steel fasteners are susceptible to galling; apply appropriate anti-seize compound when driving into stainless mating material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorx Drive Size\u003c\/strong\u003e: T15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4.8A1BS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699752075570,"sku":"4.8A1BS","price":1032.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a02741dfef1c1bececf9cb06e395e65.jpg?v=1788380308","url":"https:\/\/voomisupply.com\/products\/value-collection-4-8a1bs-size-8-button-head-torx-sheet-metal-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
