At 3\/16 inch in diameter and 5-7\/16 inches overall length, it fits common roll pin applications found in tooling, equipment, and machinery maintenance. The 2-3\/4 inch tip length provides enough reach to push pins fully through bores without requiring excessive repositioning. S2 steel construction delivers high impact toughness and resistance to chipping under repeated hammer blows. This punch is used by mechanics, millwrights, machinists, and maintenance technicians across industrial and commercial service work.\u003c\/p\u003e\n\u003cp\u003eThe J49316S2 suits roll pin removal and installation tasks on equipment such as linkages, shafts, housings, and mechanical controls. The 3\/16 inch punch size matches standard roll pin diameters common in light-to-medium duty assemblies. Its compact profile fits cleanly in a roll pin punch set alongside other sizes for complete coverage of common pin diameters. This punch is appropriate for both shop bench work and field service applications where a reliable, correctly sized punch is required to avoid deforming the workpiece or the pin bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eS2 tool steel construction resists chipping and fracture under hammer impact\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch punch diameter for standard roll pin fitment\u003c\/li\u003e\n  \u003cli\u003e5-7\/16 inch overall length provides controlled reach in confined assemblies\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch tip length allows full pin travel through the bore\u003c\/li\u003e\n  \u003cli\u003eCompact 0.4 inch cross-section minimizes interference in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/16 inch roll pins in mechanical assemblies across industrial, commercial, and equipment maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways use a ball-peen or dead-blow hammer rated for punch work — never use a claw hammer or rubber mallet that can deflect the punch under load. Support the workpiece securely in a vise or on a bench block before driving or extracting a roll pin to prevent part movement and bore damage. Inspect the punch tip before each use and replace if the tip shows mushrooming, cracking, or deformation, as a damaged tip can damage the pin bore or become a safety hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePunch Type\u003c\/strong\u003e: Roll Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: S2 Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePunch Size\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.126 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J49316S2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540431470898,"sku":"J49316S2","price":21.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66c92d67fbae1e19b9e99e35ba51fea3.jpg?v=1785854947","url":"https:\/\/voomisupply.com\/products\/proto-j49316s2-roll-pin-punch-3-16-inch-s2-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
