This plunger uses a 5\/8-11 thread and delivers an initial end force of 3 pounds building to a final end force of 6 pounds, providing a secure and repeatable locking engagement. The maximum plunger diameter is 0.311 inches, with a plunger projection of 0.3125 inches and a total plunger length of 2.186 inches. A licensed machinist or industrial maintenance technician typically installs this component in precision positioning or panel-mounting assemblies.\u003c\/p\u003e\u003cp\u003eThis plunger is suited for use in industrial machinery, tooling fixtures, jigs, and equipment panels where a flush or recessed actuation point is required. The knobless threaded stud design allows a separate knob or handle to be installed by the end user, providing flexibility in assembly configurations. The 1 inch thread length and 1.3125 inch length under head allow for straightforward integration into standard fixture plates and machined housings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger with integrated locking element for positive retention\u003c\/li\u003e\n\u003cli\u003eKnobless threaded stud design accepts user-supplied or aftermarket knob\u003c\/li\u003e\n\u003cli\u003e5\/8-11 external thread with 1 inch thread length for secure panel mounting\u003c\/li\u003e\n\u003cli\u003eStud thread size of 1\/2-13 for compatible knob or handle attachment\u003c\/li\u003e\n\u003cli\u003eInitial end force of 3 pounds, final end force of 6 pounds for consistent spring-loaded engagement\u003c\/li\u003e\n\u003cli\u003eHead height of 0.4375 inches (7\/16 inch) with plunger diameter tolerance of plus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit locking plunger for industrial fixturing, tooling jigs, and machine panels requiring a 5\/8-11 threaded mount with a knobless stud configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or industrial maintenance technician using standard hand tools.
