Sanitary Twist-to-Lock Knob-Style Retractable Spring Plungers
Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position. All of these plungers have a long nose that offers a large bearing surface to handle side loads. They’re often used for maintenance jobs.
Made of stainless steel, these plungers won’t corrode from frequent washdowns with harsh cleaners and sanitizers. All are self-draining with rounded edges and polished surfaces, so there are no crevices for bacteria to grow, reducing the chance of a foodborne illness. Seals block out water and keep contaminants from getting trapped in threads or grooves. They’re also bright blue, so you can easily spot broken pieces that fall into your line. The seals are FDA compliant for direct contact with food, but the lubricant is rated for incidental contact.
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.

Twist-to-Lock Pull-Ring Retractable Spring Plungers
Lock the nose into the retracted position by pulling the ring and rotating it 90°. The ring allows you to attach these spring plungers to a lanyard to secure them to machinery and prevent accidental drops. They have a long nose that provides a large bearing surface to handle side loads.
Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments.
18-8 stainless steel is chemical resistant.
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.

Threaded Plug Gauges with Calibration Certificate
These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They allow you to inspect internal threads on parts. All have a go gauge on one end and a no-go gauge on the other end. A taperlock handle lets you quickly replace worn gauges.
Check the minimum internal thread size with the go gauge end, and check the maximum internal thread size with the no-go gauge end. A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.
Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.
