Twist-to-Lock Knob-Style Retractable Spring Plungers
Smooth Knob With Hex Nut
Knurled Knob
Without Thread Locker
With Thread Locker
Smooth Knob
Lock the nose into the retracted position by pulling the knob and rotating it 90°. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Knurled knob spring plungers provide a slip-resistant surface for controlled adjustment.
Smooth knob spring plungers with a hex nut can be held in place with the nut after threading to your desired depth.
Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments. Black-oxide steel bodies resist corrosion in dry environments.
316 stainless steel is more corrosion resistant than 18-8 stainless steel and can be used in saltwater environments.
18-8 stainless steel is chemical resistant.
Brass is corrosion resistant in wet environments; brass noses are soft to minimize marring.
Plastic is chemical resistant and lightweight; acetal noses are extra soft to minimize marring soft surfaces such as aluminum.
Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.
Spring plungers with thread locker have a locking patch that adds friction to resist loosening.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.
