Spring plungers are used in a wide variety of applications for workholding, clamping, or indexing. They can be used as thrust pins or ejector pins. Also known as ball catches or ball plungers, they are common in machine building, tooling, automotive, and even consumer products.
Ball Plungers
The spring force is applied to a ball at the end of the spring plunger body, especially suited for quick detent action.
Steel, stainless steel, or ceramic balls
Steel or stainless steel bodies
Inch or metric
Slotted or hex drive
Pin Plungers
The spring force is applied to a pin with a rounded end, enabling greater travel.
Steel, stainless steel, or plastic pins
Steel or stainless steel bodies
Inch or metric
Slotted or hex drive
LONG-LOK Locking Elements
KIPP ball plungers and pin plungers are available with LONG-LOK nylon locking elements. The LONG-LOK prevents any change in position due to vibration. The spring plunger is securely held in place, but it can be adjusted, removed, or reinstalled up to 20 times with no significant loss in holding power. This is a significant advantage over other threadlock systems.
Push Fit Plungers
Push fit plungers have a smooth body designed for applications where threaded installation is not needed. Especially suited for soft materials such as aluminum, plastic, or wood. Some versions include O-rings to enable installation in overhead applications.
Stainless steel or plastic balls
Stainless steel, plastic, or brass bodies

Lateral Spring Plungers
Designed for workholding applications where a lateral force is desired to hold materials in place. Available with or without a seal to keep debris out of the spring mechanism. An optional eccentric bushing enables precise adjustment of the plunger.
