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.
Nylon Nose—Extra soft to avoid scratching delicate surfaces. Nylon is best for use on soft materials, such as aluminum. It will swell and weaken when exposed to moisture, however, so it should only be used in dry environments.
