It features a Delrin body with a stainless steel ball measuring 0.187 inches in diameter and a maximum ball reach of 0.053 inches. The 3\/8-16 threaded body measures 0.625 inches in length, delivering an initial end force of 5 pounds and a final end force of 10 pounds. This plunger is installed by mechanical assemblers, toolmakers, and machine builders in industrial and manufacturing settings where repeatable positioning force is required.\u003c\/p\u003e\n\u003cp\u003eThe D58 is suited for applications requiring controlled, consistent detent force on production fixtures, jigs, tooling plates, and machine assemblies. The Delrin body offers low friction and corrosion resistance, while the stainless steel ball provides durability at the contact point. Its purple color code allows for quick visual identification in multi-plunger assemblies. The 3\/8-16 thread makes installation straightforward in tapped bores matching that thread specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 threaded body for standard tapped-bore installation\u003c\/li\u003e\n  \u003cli\u003eDelrin body provides low friction and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eStainless steel ball for durable, long-lasting contact\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 5 pounds, final end force of 10 pounds for controlled detent action\u003c\/li\u003e\n  \u003cli\u003eMaximum ball reach of 0.053 inches suits shallow detent groove applications\u003c\/li\u003e\n  \u003cli\u003ePurple color code for fast visual identification in assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for machinery, fixtures, and tooling assemblies that accept a 3\/8-16 threaded ball plunger with controlled end force specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a wrench or hex key appropriate for the body drive style into a clean, properly tapped 3\/8-16 threaded bore. Ensure the bore depth and detent groove geometry are compatible with the 0.053-inch maximum ball reach before installation. De-energize or lock out any associated machinery before servicing or replacing plungers in active assemblies. Do not overtighten, as Delrin bodies can crack under excessive torque.\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\u003eBody Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.053 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: 10 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Delrin\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Controlled End Force\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\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: D58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52073920168242,"sku":"D58","price":15.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d233db62d561adf0722d57711f9b9d54_4b02ec09-9817-4753-a7da-6bf7b2512ea0.jpg?v=1790050807","url":"https:\/\/voomisupply.com\/products\/vlier-d58-threaded-ball-plunger-3-8-16-delrin-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
