The plunger uses a 3\/8-16 thread with a body and thread length of 0.625 inches, making it a compact fit in tight assemblies. The steel body and steel nose deliver durability under repeated cycling. An integrated locking element keeps the plunger secured in the tapped hole once installed, preventing loosening from vibration or side loads. Initial end force is 1.5 pounds and final end force is 5 pounds, placing this unit in the high-end-force category for its size class. Licensed HVAC, plumbing, or mechanical technicians as well as precision assembly professionals will encounter this type of hardware in equipment panels, jigs, and fixtures.\u003c\/p\u003e\n\u003cp\u003eThe M59N is suited for applications requiring high end force in restricted space, such as machine tool fixtures, equipment enclosures, cabinet indexing mechanisms, and precision assembly jigs. The stubby plunger length type allows installation in shallow bores or thin panels where a standard-length plunger body would not fit. The 0.186-inch maximum plunger diameter and 0.110-inch projection keep the footprint minimal while still providing positive tactile detent or locking engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStubby body length of 0.625 inches for use in restricted axial space\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 unified coarse thread for easy installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element prevents back-out from vibration or lateral loading\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for strength and wear resistance under repeated cycling\u003c\/li\u003e\n  \u003cli\u003e1.5-pound initial end force and 5-pound final end force for high-end-force detent applications\u003c\/li\u003e\n  \u003cli\u003eMaximum plunger diameter of 0.186 inches with 0.110-inch projection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded spring plunger for use in any assembly accepting a 3\/8-16 tapped hole and rated for high end force in restricted-space configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the M59N into a pre-tapped 3\/8-16 hole using a hex key or appropriate drive tool; torque to the fixture manufacturer's specification for the application. Disengage or power down any moving machinery before installation or removal to prevent injury from spring-loaded ejection of the plunger. The locking element engages the thread walls on installation, so back-out requires deliberate torque. Inspect the tapped hole for clean threads before installation to ensure the locking element seats correctly.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 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\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: High End Force, Restricted Space\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: M59N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51962116931890,"sku":"M59N","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71a24d228cc632cb73fa0c6d23aaa152.jpg?v=1789947481","url":"https:\/\/voomisupply.com\/products\/vlier-m59n-threaded-spring-plunger-3-8-16-5-8-in-stubby","provider":"Voomi Supply","version":"1.0","type":"link"}
