This set is designed for trade professionals who need a single kit to handle a wide range of fastener types, including tamperproof security fasteners found in HVAC equipment, electrical panels, and mechanical assemblies. The 39 individual bits span an extensive size range across all tip types, making it a practical bench or field kit for licensed HVAC technicians, electricians, and service professionals who regularly encounter security hardware. The set weighs 1 pound.\u003c\/p\u003e\n\u003cp\u003eThis bit set is suited for residential and light commercial service work where tamperproof fasteners are common, including HVAC unit access panels, electrical enclosures, pool equipment housings, and plumbing fixture assemblies. The inclusion of Torx security bits ranging from TR-8 to TR-40 and Tri-Wing bits from size 1 to 4 makes it especially useful for equipment manufacturers that use proprietary fastener profiles to restrict field access. Spanner bits cover sizes 4 through 10, and Square (Robertson) bits cover sizes 1 through 3.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e39-piece tamperproof bit set covering Hex, Phillips, Slotted, Spanner, Square, Torx, and Tri-Wing tip types\u003c\/li\u003e\n  \u003cli\u003eTorx security sizes T-8S, T-10S, T-15S, T-20S, T-25S, T-27S, T-30S, and T-40S (TR-8 to TR-40 range)\u003c\/li\u003e\n  \u003cli\u003eHex sizes included: 1\/8, 3\/32, 5\/32, 5\/64, 7\/64, and 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003ePozidriv point sizes 0, 1, 2, and 3 alongside Phillips sizes 1 and 2\u003c\/li\u003e\n  \u003cli\u003eSquare sizes 1, 2, and 3; Spanner sizes 4 through 10; Tri-Wing sizes 1 through 4\u003c\/li\u003e\n  \u003cli\u003eCompact 1-pound kit suitable for toolbox, van, or bench storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose tamperproof insert bit set compatible with standard 1\/4-inch hex bit drivers, impact-rated bit holders, and screwdriver handles accepting insert bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert bits are installed and removed by hand into a compatible 1\/4-inch hex driver or bit holder. Ensure the driver is rated for the torque output of the tool being used, particularly when paired with impact drivers. For work inside live electrical panels or energized HVAC controls, follow NFPA 70E lockout and tagout procedures before using any hand tools on fasteners. Inspect bits for wear or rounding before use to avoid fastener damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 39\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Tamperproof Bit Set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Types\u003c\/strong\u003e: Hex, Phillips, Slotted, Spanner, Square, Torx, Tri-Wing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Sizes\u003c\/strong\u003e: T-8S, T-10S, T-15S, T-20S, T-25S, T-27S, T-30S, T-40S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Size Range\u003c\/strong\u003e: TR-8 to TR-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Sizes\u003c\/strong\u003e: 1\/8, 3\/32, 5\/32, 5\/64, 7\/64, 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhillips Sizes\u003c\/strong\u003e: 1, 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePozidriv Sizes\u003c\/strong\u003e: 0, 1, 2, 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Sizes\u003c\/strong\u003e: 1, 2, 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpanner Size Range\u003c\/strong\u003e: 4 to 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTri-Wing Size Range\u003c\/strong\u003e: 1 to 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlotted Size Range\u003c\/strong\u003e: 6.5 to 8.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: WIHA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIHA","offers":[{"title":"Default Title","offer_id":51690207445298,"sku":"71990","price":106.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8b47b143bfe7820c200d608f1ed14de.jpg?v=1788267337","url":"https:\/\/voomisupply.com\/products\/wiha-71990-39-piece-screwdriver-insert-bit-set","provider":"Voomi Supply","version":"1.0","type":"link"}
