Spring-Loaded Guide Plungers
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.

Spring-Loaded Guide Plungers for Thin Workpieces
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.
