It features a 10-32 thread size with a 3\/4-inch thread length and a standard plunger projection of 1\/8 inch. The steel body provides durability in industrial environments, while the phenolic nose reduces surface marking on workpieces. An integrated locking element prevents the plunger from backing out under vibration. Initial end force is 2.9 pounds, with a final end force of 11.1 pounds, making it suitable for moderate-load positioning applications. Licensed machinists, toolmakers, and mechanical assembly technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe NS52P is used in jigs, fixtures, machine tool components, and precision assembly equipment where controlled detent force and repeatable part location are required. The 10-32 thread is a common size found in light-duty tooling plates and fixture bodies. The locking element makes it well-suited for applications subject to vibration or repeated cycling where plunger retention is critical. Standard plunger length classification means it fits within typical shallow-boss or plate-mounted configurations without requiring custom counterbores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-32 thread size with 3\/4-inch thread and body length for standard fixture plate installation\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch plunger projection provides controlled detent engagement depth\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for wear resistance in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003ePhenolic nose material reduces marring on contacted surfaces\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element prevents back-out under vibration or load cycling\u003c\/li\u003e\n  \u003cli\u003e2.9-pound initial end force and 11.1-pound final end force for moderate-load indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring plunger for fixtures, jigs, and mechanical assemblies using 10-32 threaded bores requiring a standard-projection detent plunger.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using a hex key or slotted driver appropriate to the plunger drive style. Ensure the mating threaded bore is clean and free of debris before threading in the plunger. The locking element should be engaged after reaching the desired plunger seating depth to prevent unintended loosening. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.092 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 11.1 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\u003ePlunger Length Type\u003c\/strong\u003e: Standard\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: NS52P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972339302706,"sku":"NS52P","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_f24a561a-d1fb-4a4c-8533-69afb0da4719.jpg?v=1789966449","url":"https:\/\/voomisupply.com\/products\/vlier-ns52p-threaded-spring-plunger-10-32-3-4-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
