Made from 1070-1090 alloy steel with a plain finish, this pin measures 0.5 inches in diameter and 3 inches in overall length. The slotted design allows the pin to compress slightly on insertion, creating a friction fit that resists vibration-induced loosening. It is installed by maintenance technicians and machinists working on mechanical assemblies, tooling, and industrial equipment where reliable, removable fastening is required.\u003c\/p\u003e\n\u003cp\u003eSlotted spring pins are a common fastening solution in mechanical assemblies across manufacturing, industrial, and maintenance applications. This pin is suited for use in shafts, linkages, hinges, and housings where a standard solid pin would require tighter tolerances. The 0.5-inch diameter and 3-inch length make it appropriate for medium-duty fastening scenarios in both light industrial and heavy equipment contexts. This part ships in a minimum order quantity of 50 units, making it suitable for shop stock, production use, or MRO replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlotted design allows radial compression for friction-fit installation without adhesives\u003c\/li\u003e\n  \u003cli\u003e1070-1090 alloy steel construction provides strength and hardness suitable for mechanical fastening\u003c\/li\u003e\n  \u003cli\u003ePlain finish — no coating or plating that could affect dimensional tolerance in tight bores\u003c\/li\u003e\n  \u003cli\u003e0.5 inches diameter and 3 inches length for medium-duty shaft and housing applications\u003c\/li\u003e\n  \u003cli\u003eInch system of measurement — compatible with standard imperial bore specifications\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 imperial-dimension slotted spring pin for use in mechanical assemblies requiring a 0.5-inch bore diameter and up to 3 inches of pin engagement depth.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSlotted spring pins are typically installed and removed by machinists or maintenance technicians using a pin punch and hammer or a press. Always ensure the receiving bore is clean and within the specified diameter tolerance before driving the pin. Inspect the pin for deformation after removal — spring pins should not be reused if the slot has closed or the body is visibly bent. Follow applicable facility safety procedures when working with pressed or driven fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eWeight\u003c\/strong\u003e: 0.097 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: R57700321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707456684338,"sku":"R57700321","price":6587.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11b186ae5d431ab942b9c7322d376bd8.jpg?v=1788440425","url":"https:\/\/voomisupply.com\/products\/value-collection-r57700321-slotted-spring-pin-0-5-in-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
