It features a 1\/2-13 body thread with a thread length of 0.875 inches and a maximum plunger diameter of 0.31 inches. The spring-loaded plunger delivers an initial end force of 0.75 pounds and a final end force of 4 pounds, with a locking element that holds the plunger in the retracted position. Machinists, tool and die technicians, and mechanical assembly professionals install this type of plunger in fixtures, jigs, and equipment panels.\u003c\/p\u003e\u003cp\u003eThis plunger is suited for use in production tooling, machine fixtures, industrial enclosures, and positioning mechanisms where a compact, threaded-body plunger with a locking retract feature is required. The knobless threaded stud design allows the unit to be installed flush or in confined spaces where a standard knob would interfere with adjacent components. The 1.125-inch length under head and 0.25-inch plunger projection make it appropriate for light-duty to moderate-duty indexing tasks on both stationary and moving assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger holds retracted position, preventing unintended engagement during setup or loading\u003c\/li\u003e\n\u003cli\u003eKnobless threaded stud body allows flush mounting in space-restricted installations\u003c\/li\u003e\n\u003cli\u003e1\/2-13 external thread with 0.875-inch thread length for secure panel or fixture mounting\u003c\/li\u003e\n\u003cli\u003eSpring end force ranges from 0.75 pounds initial to 4 pounds final for controlled indexing engagement\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.31 inches with a tight tolerance of plus 0.001 inches for consistent fit\u003c\/li\u003e\n\u003cli\u003ePlunger length of 1.937 inches and head height of 0.4375 inches for predictable dimensional integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard threaded-body locking plunger for use in industrial fixtures, jigs, machine panels, and mechanical assemblies requiring a 1\/2-13 threaded mount with a knobless stud configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using standard thread-tapping and hand tools.
