It features an M12 x 1.75 thread with a 20.5 mm thread length, a steel body with a black finish, and a steel nose. The plunger diameter measures 6.3 mm with a 6.5 mm projection. A built-in locking element secures the plunger in place after installation, preventing backing out under vibration. Initial end force is 0.77 kg and final end force is 3.86 kg, making this unit suited for light-load spring-detent functions in precision fixturing and workholding setups.\u003c\/p\u003e\u003cp\u003eThis spring plunger is commonly installed in machined bores or tapped holes in tooling plates, jigs, fixtures, and mechanical assemblies where repeatable part location or detent action is required. The M12 x 1.75 thread size fits standard metric-tapped holes found in tooling blocks and fixture plates across general manufacturing, CNC machine shops, and industrial assembly operations. Its short plunger length keeps the installed profile compact in space-constrained fixture designs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread with 20.5 mm thread length for secure installation in metric-tapped holes\u003c\/li\u003e\n\u003cli\u003e6.5 mm plunger projection provides consistent detent engagement depth\u003c\/li\u003e\n\u003cli\u003eLocking element prevents plunger from backing out under vibration or repeated cycling\u003c\/li\u003e\n\u003cli\u003eSteel body and steel nose for durability in metal tooling and fixture environments\u003c\/li\u003e\n\u003cli\u003eBlack finish for corrosion resistance and visual identification\u003c\/li\u003e\n\u003cli\u003eShort plunger length type suits compact or low-profile fixture designs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new installation for metric-tapped M12 x 1.75 threaded spring plunger applications in tooling plates, jigs, and mechanical fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machining or confirming a clean M12 x 1.75 tapped hole to the required depth and thread class tolerance. Ensure the bore is free of chips and debris before threading the plunger in by hand, then torquing with an appropriate spanner or hex tool. Engage the locking element per the manufacturer procedure to prevent rotation after final positioning. Depressurize or de-energize any pneumatic or hydraulic system associated with the fixture before servicing spring plungers in the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 20.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 20.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.77 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3.86 kg\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JERGENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51972506911026,"sku":"27175","price":17.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad18ca3cc7e05e598a3c97914111acf2.jpg?v=1789969644","url":"https:\/\/voomisupply.com\/products\/jergens-27175-threaded-spring-plunger-m12-x-1-75-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
