Ball-Nose Spring Plungers
 |
 |
Align, position, and lock moving parts for most machining and assembly tasks. These spring plungers have a spring-loaded ball that compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Unlike long-nose spring plungers, the ball rolls easily in and out of position, so they're a great fit for applications that require consistent, smooth movement, such as positioning parts in an assembly line and aligning fixtures and jigs when cutting or drilling.
Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
440C Stainless Steel Nose—The strongest, most wear-resistant stainless steel noses, these grind against hard metal surfaces without denting or scratching. However, they are not as corrosion resistant as 316 stainless steel.
Rail-Mount Push/Pull Toggle Clamps
 |  |
Mount these clamps to a rail or bar. A pushing or pulling motion holds workpieces from the side. Clamps secure in two positions—when the plunger is fully extended and when the plunger is fully retracted. The plunger is internally threaded to accommodate threaded holding screws and other threaded fixtures (not included).
