Flush Profile |
When you can't tap threads in your mounting surface, push these spring plungers into unthreaded holes. They work well in wood, plastic, and other soft materials that might crack if you try to cut threads. The spring-loaded ball compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place.
For a snug fit, use an arbor press to install these spring plungers in a slightly smaller hole than the body diameter.
Flanged Profile—The flanged body stops the spring plunger from sliding back through the hole when the nose compresses under a strong force. It also acts as a gripping tab so you can pull the plunger out to make adjustments.
Flush Profile—These plungers mount flush against the surface to prevent snagging.
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.
420 Stainless Steel Nose—Highly wear resistant, the nose grinds against hard metal surfaces without denting or scratching. However, 420 stainless steel is not quite as corrosion resistant as 316 stainless 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.
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.
Knurled Body—A knurled body grips more securely than a smooth body, so the spring plungers won't slip or rotate due to vibration.
Smooth Body—These spring plungers slide effortlessly into unthreaded holes, but don't grip quite as firmly as those with a knurled body.

Tight-Hold Ball-Nose Spring Plungers
 |  |
Flanged Profile | Flanged Profile |
These spring plungers defy gravity by gripping unthreaded holes, even in overhead and vertical applications. They have an O-ring that squeezes against the sides of the hole to keep the plunger firmly in place. The spring-loaded ball compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Use these spring plungers to hold parts in vertical conveyor systems and lock attachments on overhead machinery.
Flanged Profile—The flanged body stops the spring plunger from sliding back through the hole when the nose compresses under a strong force. It also acts as a gripping tab so you can pull the plunger out to make adjustments.
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.

Retractable Spring Plungers for Panels
Press Fit
 |
 |
 |
Best for thick panels. Use an arbor press or similar pressure tool to install these spring plungers into the outer panel.
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.
Twist-to-Lock—Pull back the handle and twist to lock the nose in its retracted position.
