The body is machined from steel and accepts a 3\/8-16 thread with a thread length of 1-1\/8 inches. The phenolic nose plunger projects 3\/16 inches and delivers an initial end force of 5.5 pounds and a final end force of 14.5 pounds, providing consistent spring-loaded retention. A locking element is included to secure the plunger in the threaded bore once installed. Machinists, toolmakers, and maintenance technicians install this type of hardware in fixtures, jigs, and light industrial equipment.\u003c\/p\u003e\u003cp\u003eThis spring plunger is suited for use in drill fixtures, machine tool assemblies, workholding devices, and any application requiring repeatable spring-loaded positioning. The phenolic nose reduces marring on soft workpiece surfaces, making it appropriate for fixture work where contact marking is a concern. It is sold individually and fits standard 3\/8-16 threaded holes in steel or aluminum bodies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel body construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003ePhenolic nose minimizes surface marring on contact\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread size with 1-1\/8 inches thread length for secure installation\u003c\/li\u003e\n\u003cli\u003eInitial end force of 5.5 pounds and final end force of 14.5 pounds\u003c\/li\u003e\n\u003cli\u003e3\/16 inches plunger projection provides positive spring-loaded engagement\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element locks plunger position in the threaded bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-installation spring plunger for any assembly or fixture that uses a standard 3\/8-16 threaded bore requiring a spring-loaded plunger with a 1-1\/8 inches thread length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a tapped 3\/8-16 hole using an appropriate hex key or spanner tool on the body flats. Torque the body until the locking element engages the threads to prevent back-out under vibration. Ensure the bore is clean and free of chips or debris before installation. No special tools beyond standard hand tools are required for typical fixture applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 14.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Phenolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWPN-6-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51689854173490,"sku":"SWPN-6-PT-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a.jpg?v=1788264761","url":"https:\/\/voomisupply.com\/products\/gibraltar-swpn-6-pt-g-threaded-spring-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
