The plunger features a 1\/2-13 thread with a 0.75 inch thread length and a maximum plunger diameter of 0.248 inches. Projection measures 0.151 inches, making it well suited for tight clearance environments. The body is constructed from stainless steel for corrosion resistance, while the nose is Delrin for controlled contact without marring mating surfaces. Initial end force is 5 pounds and final end force is 28 pounds. Machinists, tool and die technicians, and mechanical assembly professionals typically install this type of component.\u003c\/p\u003e\u003cp\u003eThis spring plunger is used in fixtures, jigs, tooling plates, and mechanical subassemblies where repeatable positioning or light retention force is required. The stubby body length of 0.75 inches suits applications with limited depth in the receiving bore. The stainless steel body makes it appropriate for environments where mild corrosion exposure or washdown conditions are a concern. No locking element is present, so installation relies on standard thread engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 thread size with 0.75 inch thread length for straightforward installation into tapped bores\u003c\/li\u003e\n\u003cli\u003eStubby plunger style at 0.75 inch body length for shallow-depth applications\u003c\/li\u003e\n\u003cli\u003eStainless steel body provides corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003eDelrin nose material for low-friction, non-marring contact with mating surfaces\u003c\/li\u003e\n\u003cli\u003e5 pound initial end force and 28 pound final end force for light-duty detent and positioning\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  relies on standard thread engagement for retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded spring plunger for industrial fixtures, tooling plates, jigs, and mechanical assemblies requiring a 1\/2-13 tapped bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger into a pre-tapped 1\/2-13 bore using a standard hex key or spanner wrench as appropriate for the drive style. Ensure the receiving bore is clean and free of debris before installation to prevent thread damage. Torque to the assembly specification defined by the fixture or equipment design  -  do not over-tighten, as this may deform the plunger body or restrict plunger travel. Depressurize or de-energize any assembly before servicing components in the plunger bore area.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.151 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 28 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: Delrin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\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: SSMD60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":68067523232050,"sku":"SSMD60","price":16.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9f9deb28a53c96cc04d71592592c5bb_78cca647-e73f-4796-b1e5-f4176c63ba7d.jpg?v=1793075170","url":"https:\/\/voomisupply.com\/products\/vlier-ssmd60-threaded-spring-plunger-1-2-13-stubby","provider":"Voomi Supply","version":"1.0","type":"link"}
