Measuring 0.125 inches in diameter and 1.25 inches in length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The coiled construction allows the pin to compress during installation, creating consistent radial pressure against the hole wall for a reliable, self-retaining fit. It is a standard inch-system fastener suited for production and maintenance environments across industrial and trade applications.\u003c\/p\u003e\n\u003cp\u003eCoiled spring pins are used in a wide range of mechanical assemblies including linkages, hinges, brackets, shaft-to-hub connections, and general-purpose pin-and-hole fastening scenarios. This pin is appropriate for both light and medium-duty applications where some tolerance variation in hole diameter is expected. Its alloy steel construction provides adequate strength and fatigue resistance for repetitive loading conditions. Machinists, millwrights, HVAC technicians, and maintenance professionals commonly use coiled spring pins during equipment assembly, repair, and component replacement tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoiled spring design provides radial spring force for self-retention in drilled holes\u003c\/li\u003e\n  \u003cli\u003e0.125 inch (1\/8 inch) diameter in standard inch measurement system\u003c\/li\u003e\n  \u003cli\u003e1.25 inches overall length suits a wide range of assembly depths\u003c\/li\u003e\n  \u003cli\u003e1070-1090 alloy steel material grade offers good strength and toughness\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no coating — compatible with most lubricants and assembly compounds\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specification — intended for commercial and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system coiled spring pin for general mechanical assembly and maintenance applications requiring a 0.125 inch diameter pin hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCoiled spring pins are typically installed using a pin punch and hammer or an arbor press — avoid striking the pin at an angle to prevent distortion of the coil. Ensure the receiving hole is clean, free of burrs, and drilled to the correct diameter tolerance for the pin size before installation. De-energize and lock out any equipment before servicing assemblies that contain spring pins. Removal is performed with a punch driven from the insertion end or with a pin extractor.\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: 0.125 inches (1\/8 inch)\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\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R57700781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690288382258,"sku":"R57700781","price":1305.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbda226d6abab4b54b868b7828c0e051.jpg?v=1788268188","url":"https:\/\/voomisupply.com\/products\/value-collection-r57700781-coiled-spring-pin-0-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
