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.

Long-Nose Spring Plungers
 |  |
 |
Lock heavy moving parts securely in place. Often used in indexing applications, these have a longer nose than ball-nose spring plungers to withstand greater side forces without disengaging. The nose compresses when a part presses against it, and then pops out into deep notches or grooves for a strong hold.
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.
Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.
18-8 Stainless Steel Nose—The choice for wet and outdoor environments, 18-8 stainless steel resists rusting. It's strong enough for most jobs, but won't withstand stress and vibration as well as steel.
Acetal Nose—The best plastic for damp and wet environments, acetal won't swell or lose strength if exposed to moisture. These noses are extra soft to avoid scratching delicate surfaces. They are best for use on soft materials, such as aluminum.

Vacuum Cup Levelers
 |  |
Male and Female Connections |
Save time aligning your vacuum cups manually between pick-and-place tasks. Also known as spring plungers, these levelers use a spring to automatically adjust for height and alignment differences with each stroke. Because the spring also creates a gentle point of contact with your object, these levelers help your vacuum cups last longer. They don’t rotate, so your object will stay in the same position—use them in repetitive vacuum lifting applications where precision is required.
Choose levelers based on the required stroke length and thread compatibility with your cup and system. Tighten the mounting nuts on the body to secure them in a panel or to a mounting bracket.
Auto-Adjusting Push Toggle Clamps
 |  |
Clamps hold workpieces of different thicknesses without manual adjustment. |
Hold workpieces of different thicknesses with one clamp. These clamps automatically adjust to compensate for variations in size. They secure when the plunger is fully extended to hold your workpiece from the side. The holding screw has a nonmarring tip.
