It features an 8-32 thread size with a 5\/8-inch thread length and a steel body for durability in industrial environments. The phenolic nose keeps the plunger tip non-marring, making it suitable for use against finished or coated surfaces. Initial end force is 0.70 pounds, with a final end force of 2.30 pounds, providing consistent spring-loaded engagement. A locking element is integrated into the body to secure the plunger position once installed. Typically specified by mechanical engineers and installed by machinists or maintenance technicians.\u003c\/p\u003e\u003cp\u003eThe NS51P is suited for use in jigs, fixtures, tooling plates, and light machinery where repeatable positioning or detent action is required. The standard plunger length type and compact 3\/32-inch projection make it appropriate for shallow-travel applications where space is limited. It is commonly installed in drilled and tapped holes in metal or plastic workpieces across manufacturing, assembly, and automation environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 thread size with 5\/8-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eSteel body construction for strength and resistance to wear\u003c\/li\u003e\n\u003cli\u003ePhenolic nose material provides non-marring contact with mating surfaces\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element secures plunger position after adjustment\u003c\/li\u003e\n\u003cli\u003e0.70 lb initial end force and 2.30 lb final end force for controlled spring engagement\u003c\/li\u003e\n\u003cli\u003e3\/32-inch plunger projection for compact, shallow-travel detent applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit spring plunger for standard 8-32 tapped holes in jigs, fixtures, tooling plates, and mechanical assemblies requiring spring-loaded positioning or detent action.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 8-32 hole to the specified thread depth. Use an appropriate driver or wrench on the body flats to thread the plunger in place; engage the locking element per standard procedure to prevent loosening under vibration. De-energize or lock out any powered equipment before servicing assemblies containing this component. Do not exceed the rated end force range by over-compressing the plunger during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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 Projection\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.0680 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.70 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2.30 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: Phenolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\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: NS51P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971528622386,"sku":"NS51P","price":17.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fdeb4823700376e86ff74ab040a074d.jpg?v=1789958135","url":"https:\/\/voomisupply.com\/products\/vlier-ns51p-threaded-spring-plunger-8-32-5-8-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
