It features an M8 x 1.25 thread, a stainless steel body, and a stainless steel ball measuring 0.196 inches in diameter. The ball extends a maximum of 0.059 inches beyond the body face and delivers an initial end force of 3.37 pounds and a final end force of 6.75 pounds. A locking element is included to secure the plunger in the threaded bore after installation. The body length is 0.63 inches. This plunger is installed by machinists, maintenance technicians, and mechanical assemblers working on fixtures, tooling, and precision equipment.\u003c\/p\u003e\u003cp\u003eThe SBM8N is suited for use in industrial machinery, fixtures, jigs, and automated equipment where repeatable ball-detent positioning is required. The stainless steel construction makes it appropriate for environments with exposure to moisture, cutting fluids, or mild corrosives. It is commonly installed in bores machined to M8 x 1.25 thread specifications and is identified by a purple color code for quick field identification during assembly or maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 thread for direct installation into a matching threaded bore\u003c\/li\u003e\n\u003cli\u003eStainless steel body and stainless steel ball for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e0.196 inch ball diameter with 0.059 inch maximum ball reach\u003c\/li\u003e\n\u003cli\u003eInitial end force of 3.37 pounds and final end force of 6.75 pounds for controlled detent resistance\u003c\/li\u003e\n\u003cli\u003eLocking element included to prevent loosening after installation\u003c\/li\u003e\n\u003cli\u003ePurple color code for fast identification during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in any threaded bore machined to M8 x 1.25 specifications where a ball-detent plunger with a locking element is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using a hex key or spanner wrench suited to the plunger body. The mating bore must be threaded to M8 x 1.25 before installation. Engage the locking element per the manufacturer procedure to prevent the plunger from backing out under vibration or repeated cycling. Do not overtighten, as this can distort the body or impair ball travel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.196 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.059 inches (1.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 3.37 pounds (15.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 6.75 pounds (30.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\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: SBM8N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971402203442,"sku":"SBM8N","price":16.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7285f3cd26238d3eecba0aeb94e8604.jpg?v=1789956914","url":"https:\/\/voomisupply.com\/products\/vlier-sbm8n-threaded-ball-plunger-m8-x-1-25-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
