The plunger features a 3\/8-16 thread size with a 1.18-inch thread length and a 2-inch body length. Spring force ranges from 0.75 pounds initial to 3.75 pounds final end force, providing controlled resistance suited to light-duty indexing tasks. The locking element secures the plunger in the retracted position, preventing unintended engagement during assembly or adjustment. Machinists, maintenance technicians, and mechanical assemblers install this type of component in fixtures, jigs, and positioning equipment.\u003c\/p\u003e\u003cp\u003eThe SSFR375P is suited for use in fixtures, tooling plates, machine guards, and mechanical assemblies where repeatable positioning or panel locking is required. The stainless steel construction makes it appropriate for environments where corrosion resistance matters, such as food-processing equipment, wet industrial environments, or outdoor mechanical enclosures. The L-handle design allows manual retraction and locking without additional tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking element holds plunger retracted for hands-free positioning\u003c\/li\u003e\n\u003cli\u003eStainless steel handle and body for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread for standard installation in tapped holes\u003c\/li\u003e\n\u003cli\u003e0.25-inch plunger diameter with 0.56-inch projection at full extension\u003c\/li\u003e\n\u003cli\u003eSpring force range: 0.75 pounds initial to 3.75 pounds final end force\u003c\/li\u003e\n\u003cli\u003eTool-free manual retraction via L-handle design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-installation spring plunger for machinery, fixtures, and assemblies requiring a 3\/8-16 tapped hole and a locking L-handle plunger configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 3\/8-16 through or blind hole in the mating component. Thread the plunger body into the tapped hole by hand before tightening with the appropriate hex wrench to the hex flat sized at 0.38 inches. Power down or de-energize any associated equipment before servicing plunger assemblies mounted in active machinery. Do not overtighten, as this can distort the thread or affect spring function.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Between Head and Thread\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Diameter\u003c\/strong\u003e: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VLIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SSFR375P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971448406322,"sku":"SSFR375P","price":32.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ec17ad4e41706718ae038e58c73d2ed.jpg?v=1789957523","url":"https:\/\/voomisupply.com\/products\/vlier-ssfr375p-locking-l-handle-spring-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
