The body is machined from Delrin, a durable acetal resin, and houses a stainless steel ball with a 0.125-inch diameter. The plunger threads in on a 1\/4-20 thread, with an overall body length of 0.531 inches and a maximum ball reach of 0.03 inches. Initial end force is 2 pounds and final end force is 5 pounds, making this suitable for applications requiring repeatable, low-to-moderate detent force. Color coded purple for quick identification during assembly and maintenance.\u003c\/p\u003e\u003cp\u003eBall plungers like the D54 are used in tooling, jigs, fixtures, machine slides, and light-duty indexing applications where a spring-loaded ball is needed to locate, retain, or register a component. The 1\/4-20 thread allows installation directly into tapped holes in metal, plastic, or composite assemblies. The Delrin body is well suited for environments where non-metallic contact surfaces are preferred, such as applications involving soft workpieces or where metal-to-metal contact must be avoided.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 threaded body for direct installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eStainless steel ball for corrosion resistance and smooth engagement\u003c\/li\u003e\n\u003cli\u003eDelrin acetal body reduces weight and provides non-metallic contact\u003c\/li\u003e\n\u003cli\u003eControlled end force: 2 pounds initial, 5 pounds final\u003c\/li\u003e\n\u003cli\u003e0.125-inch ball diameter with 0.03-inch maximum ball reach for precise detent action\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 as an OEM-style replacement or direct-fit component for mechanical assemblies, fixtures, and indexing systems requiring a 1\/4-20 threaded ball plunger with controlled end force.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the D54 into a pre-tapped 1\/4-20 hole using a hex key or appropriate driver. De-energize or lock out any powered or pressurized system before servicing any assembly that contains this plunger. Verify that the mating thread in the receiving component is clean and free of debris before installation to ensure proper seating and consistent force output. Do not over-torque the body, as Delrin can crack under excessive clamping load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2 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\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\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: D54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972451303730,"sku":"D54","price":15.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d233db62d561adf0722d57711f9b9d54_78ee721d-1e57-460f-a46b-b5de9e285ed0.jpg?v=1789969242","url":"https:\/\/voomisupply.com\/products\/vlier-d54-threaded-ball-plunger-1-4-20-delrin","provider":"Voomi Supply","version":"1.0","type":"link"}
