Built from stainless steel, this plunger features a knurled knob for secure manual operation and a locking plunger mechanism to hold position under load. The 1\/2-13 threaded body installs into standard tapped holes with a thread length of 0.65 inches and a length under head of 0.9 inches. End force ranges from 0.5 lb initial to 4 lb final, making it suitable for light-duty positioning tasks that require repeatable, controlled engagement.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in fixtures, jigs, machine tool components, and panel assemblies where a hand-adjustable locking mechanism is required. It is a common hardware element in manufacturing, automation, and equipment maintenance environments. Installation is straightforward for millwrights, machine builders, and maintenance technicians working on mechanical assemblies requiring indexed or spring-loaded stop points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking plunger type holds position without external fastening\u003c\/li\u003e\n  \u003cli\u003eKnurled knob style provides positive grip for tool-free adjustment\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion in wash-down or humid environments\u003c\/li\u003e\n  \u003cli\u003eEnd force range of 0.5 lb initial to 4 lb final suits light-duty indexing applications\u003c\/li\u003e\n  \u003cli\u003ePlunger projection of 0.25 inches with a maximum plunger diameter of 0.249 inches\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 thread size fits standard tapped mounting holes\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 mechanical assemblies requiring a 1\/2-13 threaded locking knob plunger with a knurled head and stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a properly tapped 1\/2-13 threaded hole using hand tightening or a suitable wrench on the head flat if provided.
