It features an M12 x 1.75 thread with a 1.102-inch thread length and a steel body and nose. The plunger projects 0.157 inches from the nose and has a maximum diameter of 0.236 inches. Initial end force is 2.25 pounds, rising to a final end force of 12.36 pounds when fully compressed. Machinists, toolmakers, and maintenance technicians install this type of component in jigs, fixtures, and production equipment where repeatable part location is required.\u003c\/p\u003e\u003cp\u003eThe SML12A is suited for use in industrial fixtures, machine tool assemblies, and positioning applications where a spring-loaded ball or plunger nose provides controlled resistance against movement. Its standard-length body threads directly into a tapped M12 x 1.75 hole, making it straightforward to integrate into new or existing assemblies. Steel construction makes it appropriate for demanding shop-floor environments. This part ships individually and is sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread for direct installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003e1.102-inch thread and body length for consistent engagement depth\u003c\/li\u003e\n\u003cli\u003e0.157-inch plunger projection with 0.236-inch maximum plunger diameter\u003c\/li\u003e\n\u003cli\u003e2.25-pound initial end force and 12.36-pound final end force for controlled detent feel\u003c\/li\u003e\n\u003cli\u003eSteel body and nose construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  installs and adjusts with standard tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded spring plunger for assemblies requiring an M12 x 1.75 tapped hole with standard plunger geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger into a pre-tapped M12 x 1.75 hole using a spanner wrench or appropriate hex tool on the body flats. Ensure the mating assembly is de-energized and secured before installation. Do not overtighten, as doing so can restrict plunger travel or damage the spring mechanism. Confirm plunger projection and force requirements match the application before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.102 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.102 inches (27.99 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.157 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.236 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.25 pounds (10.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 12.36 pounds (55.00 N)\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: Standard\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: SML12A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52024306204978,"sku":"SML12A","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30cd00ede3ed0899aa62edda1da92ab2_769b5180-5680-46c3-b099-549bc3800448.jpg?v=1790014695","url":"https:\/\/voomisupply.com\/products\/vlier-sml12a-threaded-spring-plunger-m12-x-1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
