This metric pin measures 55 mm in length and 12 mm in diameter, manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins use a longitudinal slot to allow radial compression during installation, creating a secure interference fit within a drilled hole. The 1070-1080 steel construction provides strong tensile characteristics suited to moderate-to-heavy shear and vibration loads. Licensed machinists, maintenance mechanics, and industrial technicians commonly install these pins in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis pin is used in mechanical assemblies requiring a removable or permanent locating fastener in metric-dimensioned components. Typical applications include shaft-to-hub connections, linkage assemblies, gear and pulley retention, and general machine component alignment. The 12 mm diameter and 55 mm length position it for medium-to-large frame machinery, agricultural equipment, and industrial fabrication. Installation does not require threading and is compatible with standard drilled metric holes at the nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55 mm overall length for medium-to-large frame mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e12 mm diameter provides a robust interference fit in nominal metric bores\u003c\/li\u003e\n  \u003cli\u003e1070-1080 steel grade delivers strong shear resistance and durability\u003c\/li\u003e\n  \u003cli\u003eSlotted design allows radial compression for tool-driven or press installation and removal\u003c\/li\u003e\n  \u003cli\u003ePlain finish suitable for dry or lubricated installation environments\u003c\/li\u003e\n  \u003cli\u003eMetric dimensioning for direct fit in metric-specified hole patterns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard metric slotted spring pin for mechanical assemblies requiring a 12 mm diameter nominal bore with 55 mm pin length per metric fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed machinist or maintenance mechanic using a pin punch and hammer or an arbor press. Always power down and de-energize the associated machinery before installing or removing spring pins. Drive the pin flush or to the specified depth using a punch sized to the pin diameter to avoid deforming the slot. Use appropriate eye protection and follow facility-specific lockout and tagout procedures during service.\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: 55 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 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\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: 2.8 pounds\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: R57900883\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723418534194,"sku":"R57900883","price":3824.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be33b38e23f4a2e436ab7847cc0f9968_f97c466c-2b28-4e9f-ba81-1527490fac0a.jpg?v=1788604687","url":"https:\/\/voomisupply.com\/products\/value-collection-r57900883-slotted-spring-pin-55mm-12mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
