Knurled Knob Plungers

Our knurled knob plungers feature a quick release knob and hand retractable heavy-duty plunger, available in both non-locking and locking design. They provide large hardened bearing surfaces that permit greater side loading and have a slight end taper for easy alignment. The steel option is zinc with gold chromate finish. The stainless steel option offers the additional benefit of rust and corrosion resistance.
