The 5\/16-18 stud thread and 0.625-inch thread length allow secure mounting into standard tapped holes. The plunger delivers an initial end force of 1.5 pounds and a final end force of 6 pounds, providing reliable spring tension for detent and locating functions. With a maximum plunger diameter of 0.179 inches and a body length of 0.8125 inches, this is a compact unit suited for light-duty holding tasks. Installed by millwrights, machine builders, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis plunger is suited for light mechanical assemblies where a flush or recessed knob profile is needed. The knobless threaded stud configuration allows the unit to sit within a panel or housing without a protruding knob, making it appropriate for tight-clearance installations. Typical applications include fixture positioning, tooling plates, enclosure latching, and equipment alignment jigs in industrial and commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking plunger design for straightforward indexing and positioning use\u003c\/li\u003e\n  \u003cli\u003eKnobless threaded stud style suits flush-mount and tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1.5 pounds ramping to 6 pounds final end force\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 stud thread with 0.625-inch thread length for standard tapped-hole mounting\u003c\/li\u003e\n  \u003cli\u003eCompact body length of 0.8125 inches with 0.1875-inch plunger projection\u003c\/li\u003e\n  \u003cli\u003eLocking element included for secure thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for industrial assemblies requiring a 5\/16-18 non-locking threaded stud plunger with a knobless configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the stud into a pre-tapped hole of the appropriate size and torquing to the assembly specification. Disengage or de-energize any moving equipment before servicing positioning hardware. Confirm plunger projection clearance before final assembly to avoid binding.
