The body is machined from steel with a black finish, and the nose is made from Delrin for smooth, low-friction contact. The plunger threads in at M5 x 0.80 over a 0.748-inch thread length and delivers an initial end force of 1.31 kg and a final end force of 5.00 kg. The 2.36 mm maximum plunger diameter and 3 mm projection keep this a compact, precise component suited for tight-tolerance installations.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in manufacturing jigs, fixturing plates, machine tool components, and light assembly tooling where repeatable positioning or spring-loaded detent action is required. The M5 thread size makes it compatible with standard metric tapped holes found in tooling plates, machined fixtures, and precision assemblies. Installation is typical in industrial and machine shop environments by machinists, toolmakers, or maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM5 x 0.80 thread with 19 mm thread length for standard metric tooling applications\u003c\/li\u003e\n  \u003cli\u003eDelrin nose provides low-friction, non-marring plunger contact\u003c\/li\u003e\n  \u003cli\u003eSteel body with black finish for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003e3 mm plunger projection with 2.36 mm maximum plunger diameter for compact fitment\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1.31 kg and final end force of 5.00 kg for reliable detent action\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  free-spinning installation for quick adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard metric threaded spring plunger for use in M5 x 0.80 tapped holes in tooling plates, machined fixtures, jigs, and precision assembly equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a 2.5 mm hex key. Thread the plunger into a clean, properly tapped M5 x 0.80 hole and tighten to seat the body flush or to the desired depth. Ensure the mating bore or detent groove aligns with the plunger projection before final positioning. De-energize or lock out any associated equipment before servicing or replacing plungers in active fixtures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5 x 0.80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 19 mm (0.748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 19 mm (0.748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 2.36 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.31 kg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 5.00 kg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 2.50 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: Delrin\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: 30471\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":51970914124082,"sku":"30471","price":16.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42538ccc73a5e558154a507f9fb9ab08_885a5c14-1007-4280-9a3b-d95b86671ab6.jpg?v=1789953139","url":"https:\/\/voomisupply.com\/products\/jergens-30471-threaded-spring-plunger-m5-x-0-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
