It uses a spring-loaded steel nose to apply controlled end force against a mating surface, holding components in position without permanent fastening. The M63 features a 5\/8-11 thread with a 1.062-inch thread length and a maximum plunger diameter of 0.31 inches. Initial end force is 2 pounds, rising to 8.5 pounds at full compression. The steel body and steel nose make it suitable for general industrial and machine-shop environments where moderate force retention is required.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in fixture plates, jigs, tooling bodies, machine slides, and similar mechanical assemblies where repeatable positioning or light detent resistance is needed. The stubby plunger length type suits applications with limited depth clearance. It installs directly into a threaded hole in the host component, making it a straightforward retrofit or OEM replacement in both new builds and field repairs. Suitable for light industrial, tooling, and precision mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 thread for direct installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eStubby plunger profile for use in tight-clearance applications\u003c\/li\u003e\n  \u003cli\u003e2-pound initial end force with 8.5-pound final end force for controlled detent action\u003c\/li\u003e\n  \u003cli\u003e0.215-inch plunger projection provides consistent contact depth\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in general industrial environments\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  standard free-spinning installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded spring plunger for mechanical assemblies, fixtures, and tooling that accept a 5\/8-11 threaded spring plunger with a stubby plunger configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the M63 into a properly tapped 5\/8-11 hole using a standard hex wrench or spanner. Ensure the mating thread is clean and free of debris before installation. No special tools are required, but thread engagement should be confirmed to the full 1.062-inch thread length for proper force performance. Disengage or de-energize any moving components in the assembly before servicing or replacing 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: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.215 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 8.5 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: None\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: M63\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972187947314,"sku":"M63","price":24.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db9dc064fbc866102d7f53c3f8f376a6_15854436-92d4-40ce-be7d-daf0d8509fde.jpg?v=1789963978","url":"https:\/\/voomisupply.com\/products\/vlier-m63-threaded-spring-plunger-5-8-11-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
