It features a 3\/8-16 thread, a 0.187-inch stainless steel ball, and a steel body measuring 5\/8 inch in length. The built-in locking element secures the plunger in position after installation, preventing backout under vibration or repeated cycling. With a 5-pound initial end force and a 10-pound final end force, this plunger delivers consistent, repeatable engagement suited to precision assembly and tooling work. Machinists, tool and die makers, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe 52811 is used in manual and automated tooling fixtures, workholding devices, index plates, and precision jigs where a spring-loaded ball detent is needed to locate or retain a component. The 3\/8-16 thread allows installation into standard tapped holes in steel, aluminum, or cast iron assemblies. The stainless steel ball resists wear and corrosion in light-fluid or high-cycle environments. This plunger is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 threaded body for installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e0.187-inch stainless steel ball for wear and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSteel body, 5\/8 inch in length, for rigid, repeatable installation\u003c\/li\u003e\n  \u003cli\u003eLocking element prevents plunger backout under vibration\u003c\/li\u003e\n  \u003cli\u003e5-pound initial end force and 10-pound final end force for consistent detent action\u003c\/li\u003e\n  \u003cli\u003e0.048-inch maximum ball reach for controlled engagement depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install threaded ball plunger for fixturing and tooling assemblies using a standard 3\/8-16 tapped hole.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a hex wrench or spanner into a clean, properly tapped 3\/8-16 hole. Disengage and de-energize any associated machinery before servicing or replacing plungers in active tooling fixtures.
