The plunger features an M8 x 1.25 thread with a 16 mm thread length, a maximum plunger diameter of 3.43 mm, and a 5 mm projection. The steel body includes a locking element to secure the plunger position once set, preventing loosening from vibration during operation. The nose is constructed from Delrin or steel depending on the application requirement. A black finish on the body provides basic corrosion resistance. This component is typically installed by machinists, tool and die makers, and mechanical assemblers working with fixturing and workholding setups.\u003c\/p\u003e\n\u003cp\u003eThe JERGENS 26773 is suited for light-duty indexing and detenting applications in industrial and manufacturing environments. It fits M8 x 1.25 threaded through-holes or blind holes in fixture plates, jig bodies, and machine components. Initial end force is 0.23 kg and final end force is 4.54 kg, making it appropriate for applications requiring controlled, repeatable spring resistance during engagement and release. The locking element allows the installed plunger to be torqued in place without requiring thread-locking compounds in most setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM8 x 1.25 thread with 16 mm thread length for standard metric fixture holes\u003c\/li\u003e\n  \u003cli\u003e3.43 mm maximum plunger diameter with 5 mm projection\u003c\/li\u003e\n  \u003cli\u003eSteel body with black finish for durability and basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDelrin and steel nose material options for controlled wear characteristics\u003c\/li\u003e\n  \u003cli\u003eBuilt-in locking element resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 0.23 kg and final end force of 4.54 kg for light-duty indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or original-specification spring plunger for M8 x 1.25 threaded holes in industrial fixtures, jig plates, and workholding components requiring a short-length plunger with locking element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or mechanical assembler using a hex wrench sized for the plunger body. Ensure the receiving threaded hole is clean and properly tapped to M8 x 1.25 before installation. The locking element should be engaged to the manufacturer specification to prevent back-out during service. De-energize or lock out any powered equipment before accessing fixtures containing spring plungers.\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: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Short\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\u003ePlunger Projection\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.23 kg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.54 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: Delrin and Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\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: 26773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51961196773682,"sku":"26773","price":17.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e49878305d0c98aaf88e42f26c58b6da.jpg?v=1789946846","url":"https:\/\/voomisupply.com\/products\/jergens-26773-threaded-spring-plunger-m8-x-1-25","provider":"Voomi Supply","version":"1.0","type":"link"}
