Measuring 0.2188 inches in diameter and 1.25 inches in overall length, this pin is manufactured from 1070-1090 grade alloy steel with a plain finish. Its coiled construction allows the pin to compress and expand to absorb shock and vibration loads, distributing stress along the full length of the coil rather than concentrating it at a single point. This makes it well suited to dynamic or high-cycle applications where a solid pin would be prone to fatigue failure.\u003c\/p\u003e\n\u003cp\u003eCoiled spring pins of this type are used in a wide range of industrial, mechanical, and equipment-maintenance applications, including motor shaft retention, linkage assemblies, gear and pulley mounting, and fixture work. They are installed by machinists, millwrights, maintenance technicians, and mechanical assemblers working on both production and repair tasks. The 7\/32-inch fractional diameter and 1-1\/4-inch length fit standard drilled holes in typical light-to-medium-duty assemblies. This pin is sold individually per package with a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoiled construction distributes stress along the full pin length, resisting fatigue under vibration and shock loads\u003c\/li\u003e\n  \u003cli\u003e0.2188-inch (7\/32-inch) nominal diameter fits standard drilled holes in inch-series assemblies\u003c\/li\u003e\n  \u003cli\u003e1.25-inch overall length suitable for light-to-medium-duty retention applications\u003c\/li\u003e\n  \u003cli\u003e1070-1090 grade alloy steel provides good strength and toughness\u003c\/li\u003e\n  \u003cli\u003ePlain finish — no added coating that could affect dimensional tolerance in tight-tolerance bores\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — intended for commercial and industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series coiled spring pin for use in commercial and industrial mechanical assemblies requiring a 0.2188-inch diameter retention pin.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCoiled spring pins are driven into pre-drilled holes using a pin punch and hammer or an arbor press — avoid using a standard drift that could splay the coil ends. Support the workpiece fully to prevent stress on surrounding components during installation. Always confirm hole depth and diameter before pressing to prevent pin over-insertion or bore damage. Remove power, pressure, or stored energy from any assembly before servicing or replacing retention pins.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Coiled Spring Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inches fractional)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1070-1090\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: Inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: R57700837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693451575602,"sku":"R57700837","price":1496.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57c19218c91ba7d0fccb01ab79ed275d.jpg?v=1788312552","url":"https:\/\/voomisupply.com\/products\/value-collection-r57700837-coiled-spring-pin-0-2188-in","provider":"Voomi Supply","version":"1.0","type":"link"}
