Spring pins, also called roll pins or slotted pins, are cylindrical fasteners with a longitudinal slot that allows radial compression during installation. This compression creates a constant outward spring force against the bore wall, locking the pin in place without adhesives or secondary fasteners. At 45 mm in length and 4 mm in diameter, this pin suits light- to medium-duty fastening and alignment applications. Machinists, maintenance technicians, and assembly professionals install these pins across a wide range of mechanical and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis slotted spring pin is suited for use in mechanical assemblies requiring a reliable, removable pin fastener. Typical applications include shaft-to-hub connections, hinge pivots, clevis linkages, gear and sprocket retention, and jig-and-fixture alignment. The metric sizing makes it appropriate for equipment built to metric standards. It is commonly used in industrial machinery, agricultural equipment, and general manufacturing assembly environments where a reusable pin fastener is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlotted design allows radial compression for secure interference fit in drilled bores\u003c\/li\u003e\n  \u003cli\u003e1070-1080 grade carbon steel construction provides strength suitable for medium-duty fastening loads\u003c\/li\u003e\n  \u003cli\u003e45 mm overall length in metric sizing for compatibility with metric-dimensioned assemblies\u003c\/li\u003e\n  \u003cli\u003e4 mm diameter for use in standard 4 mm drilled or reamed holes\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no coating or plating, suitable for indoor or lubricated environments\u003c\/li\u003e\n  \u003cli\u003eReusable and removable with standard pin punches and installation tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose metric slotted spring pin for use in any application requiring a 4 mm diameter, 45 mm long roll pin in a drilled or reamed through-hole or blind-hole bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSlotted spring pins are installed by qualified maintenance technicians or machinists using a pin punch and hammer or an arbor press. Ensure the receiving bore is clean and free of burrs before driving the pin. Align the slot orientation perpendicular to the primary load direction when possible to maximize fatigue resistance. To remove the pin, use a properly sized pin punch to drive it through the bore or back it out without damaging the bore walls.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Slotted Spring Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1070-1080 Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163201\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R57900669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720422916402,"sku":"R57900669","price":1391.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93c7e6a6e7e8d09f6164613a4db7d381.jpg?v=1788563726","url":"https:\/\/voomisupply.com\/products\/value-collection-r57900669-slotted-spring-pin-45mm-4mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
