The body and nose are both constructed from stainless steel, making this plunger suitable for environments where corrosion resistance is a priority. It features a 1\/4-20 thread with a 1 inch thread length and a 3\/16 inch projection. Initial end force is 3 pounds and final end force is 13 pounds, giving the installer a defined feel and repeatable positioning force. Machinists, tool-and-die technicians, and mechanical assembly professionals are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe SSS54 is used in jigs, fixtures, tooling plates, and precision mechanical assemblies where a spring-loaded ball or nose is needed to locate or retain a moving part at a set position. The 1\/4-20 thread size is a common standard that fits a wide range of tapped holes in aluminum, steel, and other structural materials. Its stainless steel construction makes it appropriate for washdown environments, food-processing adjacent applications, and any setting where mild chemical or moisture exposure is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel body and nose for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 thread for easy installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1 inch thread length provides solid thread engagement depth\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection with defined initial and final end forces\u003c\/li\u003e\n  \u003cli\u003e3 pound initial end force and 13 pound final end force for repeatable detent feel\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  allows adjustment and removal after installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-installation spring plunger for any application requiring a 1\/4-20 threaded spring plunger with standard 1 inch body length and stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the SSS54 into a pre-tapped 1\/4-20 hole using a hex key or appropriate driver on the body hex. Ensure the receiving material has sufficient thread engagement depth to match the 1 inch thread length. No locking element is present, so a thread-locking compound may be applied if permanent positioning is required. Deburr and clean the tapped hole before installation to avoid damaging the plunger nose.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.117 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SSS54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51983905227058,"sku":"SSS54","price":18.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c35c3fb65495545a1661aa94eb49286.jpg?v=1789984405","url":"https:\/\/voomisupply.com\/products\/vlier-sss54-threaded-spring-plunger-1-4-20-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
