The tool features a 3\/8-inch flat tip, a 1\/2-inch hexagonal shank, and a black oxide finish that provides corrosion resistance. Tip hardness is rated at 55 to 57 HRC, giving the working end durability against repeated impact. Manufactured in the United States and conforming to ASME B107.410-2008, this punch is built for reliable, long-term use in professional shop and field environments. It weighs 0.35 pounds and requires no handle or handguard.\u003c\/p\u003e\n\u003cp\u003eThe 21105 is suited for mechanical, automotive, and general fabrication work where pins or keys need to be removed from fasteners and assemblies without damaging surrounding components. The 1\/2-inch hex shank allows for consistent positioning and reduces rolling on work surfaces. A 1-1\/4-inch taper length transitions cleanly to the 3\/8-inch tip, keeping the punch aligned during use on standard SAE-spec fasteners and hardware. This tool is commonly found in maintenance shops, assembly lines, and field service kits where hand punch work is routine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece steel construction for maximum durability and impact resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch flat tip rated at 55 to 57 HRC for hardened working performance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides corrosion resistance without added bulk\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hexagonal shank prevents rolling and aids grip on work surfaces\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.410-2008 standard for hand punches\u003c\/li\u003e\n  \u003cli\u003eMade in the United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for SAE-spec pin and key removal applications in metal assemblies where a 3\/8-inch tip diameter is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis punch is a hand tool used by mechanics, machinists, and maintenance technicians. Before use, confirm the target pin or key is already loosened to avoid damaging the workpiece or the punch tip. Strike the punch only with an appropriate ball-peen or cross-peen hammer rated for punch work. Do not use this tool as a chisel or pry device, as lateral loading can damage the tip or shank.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Hardness\u003c\/strong\u003e: 55 to 57 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Shape\u003c\/strong\u003e: Hexagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e: 1-piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B107.410-2008\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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: MAYHEW TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAYHEW TOOLS","offers":[{"title":"Default Title","offer_id":51525287772466,"sku":"21105","price":17.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34fa84cf7410eda1320892c4742653ce.jpg?v=1785469614","url":"https:\/\/voomisupply.com\/products\/mayhew-tools-21105-pin-punch-6in-3-8in-tip-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
