Machined from stainless steel throughout, the body measures 0.625 inches in length with a 3\/8-16 thread size and a maximum plunger diameter of 0.186 inches. The plunger projects 0.11 inches at full compression. Initial end force is 1.5 pounds, and final end force reaches 5 pounds, making this plunger well suited to high end force requirements in tight installations. Licensed trades and precision assembly technicians use this type of hardware in mechanical fixtures, tooling, and controlled-movement assemblies.\u003c\/p\u003e\u003cp\u003eThe SSM59 fits applications where a standard-length spring plunger would not clear surrounding structure. The stubby body length of 0.625 inches allows installation into shallow-tapped bores in fixtures, jigs, dies, machine frames, and similar assemblies. The 3\/8-16 thread is a common unified coarse size, compatible with standard tapped holes in steel, aluminum, and other structural materials. Stainless steel construction makes it appropriate for environments with moisture exposure or where corrosion resistance is a factor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStubby plunger length type for restricted-space installations\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread size with 0.625 inches thread length for secure engagement\u003c\/li\u003e\n\u003cli\u003e1.5 pounds initial end force and 5 pounds final end force for high end force applications\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.186 inches with 0.11 inches projection\u003c\/li\u003e\n\u003cli\u003eFull stainless steel construction  -  body and nose  -  for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eNo locking element, allowing straightforward installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in high end force, restricted-space applications requiring a 3\/8-16 threaded spring plunger with a stubby body profile.

Use an appropriate hex key or spanner tool per the manufacturer specification for the drive style present on this plunger. De-energize or lock out any machine or fixture before installing or replacing spring plungers. Do not exceed the rated final end force by over-compressing the plunger, as this can damage the internal spring and alter positioning performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.11 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\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\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: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: High End Force, Restricted Space\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: SSM59\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52014278869298,"sku":"SSM59","price":15.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e7aff049003694a66fe74c10d5edad5.jpg?v=1790006846","url":"https:\/\/voomisupply.com\/products\/vlier-ssm59-threaded-spring-plunger-3-8-16-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
