The plunger features an M8 x 1.25 thread with a 25 mm thread length and a steel body with a black finish, providing corrosion resistance and durability in shop environments. The plunger nose measures 3.43 mm in diameter with a 5 mm projection, delivering an initial end force of 1.35 kg and a final end force of 6.75 kg. Installation and adjustment require a 4 mm hex key. This part is typically installed by machinists, toolmakers, or maintenance technicians working on fixtures, jigs, and automation tooling.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is suited for use in machine fixtures, assembly jigs, tooling plates, and light-duty positioning mechanisms across manufacturing and industrial maintenance applications. It is threaded directly into tapped holes and functions without a separate locking element, making it appropriate for locations where removal and repositioning are expected during normal operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8 x 1.25 thread size with 25 mm thread length for secure installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.43 mm diameter steel nose with 5 mm plunger projection for precise detent engagement\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1.35 kg and final end force of 6.75 kg for controlled indexing feel\u003c\/li\u003e\n  \u003cli\u003eSteel body and nose construction with black finish for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e4 mm hex drive for easy installation and torque adjustment with a standard hex key\u003c\/li\u003e\n  \u003cli\u003eNo locking element, allowing straightforward removal and repositioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit threaded spring plunger for any application with a standard M8 x 1.25 tapped hole requiring a light-duty spring-loaded positioning or detent element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the plunger into a pre-tapped M8 x 1.25 hole using a 4 mm hex key. Ensure the mating hole is clean and free of chips or debris before threading in the plunger to avoid thread damage. Do not overtighten, as excess torque can compress the internal spring beyond its rated travel and reduce plunger function. Always verify plunger projection and force specifications match the application requirements before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 3.43 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.35 kg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 6.75 kg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 4 mm\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: 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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 26873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":67907272769842,"sku":"26873","price":16.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0bfe8d22efb8cfc210fab9f1a6adfe9.jpg?v=1791176169","url":"https:\/\/voomisupply.com\/products\/jergens-26873-threaded-spring-plunger-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
