Quick to install, position, and remove, these knobs have an angled hole that allows you to tilt the knob to slide it over threads, then straighten it to grip the threads and secure the knob. They provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery.

Steel knobs are stronger than phenolic knobs.

These rugged steel handles provide lasting durability for applications involving frequent positioning, tightening, and holding adjustments. Lift the handle to rotate freely; then release the handle to engage and tighten. These handles are also known as clamping handles. All have a black-oxide finish for mild rust resistance.

Threaded-stud handles mount into a threaded hole.

Threaded-hole handles install on a threaded stud.

These handles are often used for operating machinery.

Threaded-hole handles install on a threaded stud.

Threaded through-hole handles allow long shafts to thread through these handles for mounting versatility.

Steel handles are stronger than iron handles. Those with a black-oxide finish have mild rust resistance.

Iron handles are zinc plated for corrosion resistance.

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.

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.
