It features a 3\/8-16 thread size with a 0.75-inch thread length and a non-locking stainless steel body measuring 0.94 inches in body length. The plunger delivers an initial end force of 1 pound and a final end force of 8 pounds, making it suitable for moderate-duty positioning tasks. Constructed from stainless steel, the SSL375P resists corrosion in environments where moisture or chemical exposure is a concern. Machinists, toolmakers, and mechanical assemblers typically install this component.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in jigs, fixtures, machine tool assemblies, and precision positioning mechanisms where repeatable detent action is required. The knurled knob allows manual actuation without tools, making it practical in applications where frequent operator adjustment is needed. The non-locking plunger design allows free axial travel under load, returning to position via spring force. It is appropriate for light to moderate indexing loads in both production and maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking plunger type allows free spring-loaded axial travel\u003c\/li\u003e\n  \u003cli\u003eKnurled knob handle enables tool-free manual actuation\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1 pound ramping to a final end force of 8 pounds\u003c\/li\u003e\n  \u003cli\u003eMaximum plunger diameter of 0.185 inches with a tolerance of +0.001 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003eLocking element included for secure thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install spring plunger for industrial jigs, fixtures, and indexing assemblies using a standard 3\/8-16 threaded bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a tapped 3\/8-16 hole in the mating component. Ensure the bore depth accommodates the full 0.75-inch thread length plus plunger projection before installing. De-energize or lock out any powered equipment before servicing assemblies containing this plunger. Avoid over-torquing the knob body, as stainless steel threads can gall against similar materials without proper thread lubricant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.218 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SSL375P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52123459420466,"sku":"SSL375P","price":30.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf16ebb7eaaeca7d38bb64c70f9181d6_11c4aca8-1d23-49ed-b12f-5db590a741ff.jpg?v=1790086093","url":"https:\/\/voomisupply.com\/products\/vlier-ssl375p-knob-handle-spring-plunger-3-8-16-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
