The plunger features a 5\/16-18 thread with a 5\/8-inch thread length and a maximum plunger diameter of 0.135 inches, providing a compact footprint suitable for space-constrained installations. An initial end force of 0.5 pounds and a final end force of 4.5 pounds make this unit appropriate for low-to-moderate detent and positioning tasks. The steel body and steel nose offer durability in industrial environments, and the integrated locking element secures the plunger position once installed. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is suited for use in jigs, fixtures, machine tool components, and light industrial equipment where repeatable positioning or part retention is required. The short plunger length type and 3\/16-inch projection make it well matched to shallow-bore or thin-panel applications where a standard-length plunger would not fit. The black finish provides a degree of corrosion resistance for general shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread size with 5\/8-inch thread length for secure installation in threaded bores\u003c\/li\u003e\n  \u003cli\u003eMaximum plunger diameter of 0.135 inches with 3\/16-inch projection for compact detent engagement\u003c\/li\u003e\n  \u003cli\u003e0.5 pound initial end force and 4.5 pound final end force for light indexing and positioning duty\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial and tooling applications\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element prevents plunger from backing out after installation\u003c\/li\u003e\n  \u003cli\u003eBlack finish for general corrosion resistance in shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 threaded spring plunger for use in jigs, fixtures, and mechanical assemblies requiring a short-body, low-projection detent or positioning element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly tapped 5\/16-18 threaded bore in the mating component. Use an appropriate hex key or installation tool on the locking element to secure the plunger to the specified torque recommended in the assembly drawing. Ensure the bore depth and clearance accommodate the 3\/16-inch plunger projection before final assembly. Do not exceed the rated end force range by substituting incompatible spring plungers in the same bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5\/8 inches\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: 0.135 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\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.5 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: Steel\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: 27105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52110125859122,"sku":"27105","price":16.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6296d31a263244ebf3239cfe73f7090e.jpg?v=1790076064","url":"https:\/\/voomisupply.com\/products\/jergens-27105-threaded-spring-plunger-5-16-18-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
