Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping. Press into a drilled hole using the installation tool (sold separately).

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications. A sealed top prevents debris from getting inside and making them seize up. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

As the face of these plungers is pushed in, the internal spring applies outward pressure to hold a workpiece in position against stops and rails. Plungers allow easy insertion and removal of parts in a fixture and accommodate slight variations in size from part to part. They mount on flat surfaces. Also known as spring stops.

Round face holds curved and contoured surfaces.

Square face with chamfered bottom provides extra clearance for workpieces that have weld beads or imperfections.

An acetal face is nonmarring to protect soft metal and polished surfaces. A steel face is strong and wear resistant. Choose a stainless steel face for chemical and corrosion resistance.

Set the tang in a hole or recess below the work surface to ensure thin material cannot slide underneath the plunger's face. As the face is pushed in, the internal spring applies outward pressure to hold a workpiece in position against stops or rails. Plungers allow easy insertion and removal of parts in a fixture and accommodate slight variations in size from part to part. They mount on flat surfaces. Also known as spring stops.
