Built from stainless steel with a zinc-plated finish, this plunger delivers an initial end force of 1.5 pounds and a final end force of 8 pounds, providing firm, repeatable locking engagement. The 3\/8-16 thread size and 0.75-inch thread length allow straightforward installation into tapped holes. Mechanical technicians and tooling specialists install this type of component in workholding, machine guarding, and adjustable panel applications where a knobless, flush-mount profile is required.\u003c\/p\u003e\u003cp\u003eThis plunger is suited for use in light to medium-duty industrial applications where a locking plunger with a threaded stud body is needed. The knobless design keeps the profile low, making it appropriate for recessed or space-constrained mounting points in machine frames, fixtures, and enclosures. The stainless steel construction offers corrosion resistance in wash-down or high-humidity environments. Sold individually, it fits installations requiring a single-piece replacement or new assembly component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger type with integrated locking element for positive retention\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread size with 0.75-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eInitial end force of 1.5 pounds, final end force of 8 pounds\u003c\/li\u003e\n\u003cli\u003eKnobless threaded stud style for low-profile, recessed mounting\u003c\/li\u003e\n\u003cli\u003eStainless steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.216 inches with a diameter tolerance of plus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for industrial fixtures, workholding equipment, and mechanical assemblies requiring a 3\/8-16 locking plunger with a threaded stud body.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by mechanical technicians or tooling specialists using standard hand tools.
