Built with a stainless steel body and stainless steel nose, it delivers corrosion resistance suited to demanding environments. The 8-36 thread size with a 0.437-inch thread length keeps the overall footprint compact. A locking element is incorporated into the body to secure the plunger in the threaded bore once installed. Initial end force is 0.5 pounds and final end force is 1.5 pounds, providing consistent, repeatable spring tension across the plunger travel. Mechanical assemblers, toolmakers, and precision fabricators install this component in fixtures, jigs, and production equipment.\u003c\/p\u003e\u003cp\u003eThe SSM51P is suited for light-load positioning and detent applications where a low-profile, stubby plunger body is required. The 8-36 thread makes it compatible with fine-threaded bores in aluminum, steel, or similar materials commonly found in precision fixtures and automated assembly tooling. The locking element eliminates the need for thread adhesive to prevent loosening under vibration, making it a practical choice in equipment subject to cyclic loading or frequent adjustment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel body and nose for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e8-36 thread size with 0.437-inch thread length for compact installation\u003c\/li\u003e\n\u003cli\u003eStubby plunger length type for low-profile applications\u003c\/li\u003e\n\u003cli\u003eLocking element integrated into body to resist loosening under vibration\u003c\/li\u003e\n\u003cli\u003e0.5-pound initial end force and 1.5-pound final end force for light-duty detent use\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.07 inches for fine-clearance bores\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 threaded bores accepting an 8-36 thread form in precision mechanical assemblies, fixtures, and jigs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 8-36 threaded bore in the mating component. Use an appropriate driver or spanner tool rated for the body size to avoid deforming the plunger head. Ensure the mating assembly is de-energized and depressurized before servicing any fixture or equipment containing this plunger. The integrated locking element provides resistance to back-out, but verify seating depth against assembly drawings to achieve correct projection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.07 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: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Material\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\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: SSM51P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52125386572082,"sku":"SSM51P","price":15.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db9dc064fbc866102d7f53c3f8f376a6_05f1e892-9fa8-4c64-9c8d-ecbd7a987dbb.jpg?v=1790087568","url":"https:\/\/voomisupply.com\/products\/vlier-ssm51p-threaded-spring-plunger-8-36-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
