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.

Threaded Spring-Loaded Guide Pins
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.

Create-Your-Own Spring-Loaded Guide Pins
Thread in a screw, handle, or other part to create the right size and shape guide pin for your application. 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).

Door Chains
Mount one end to the frame and the other end to the door to prevent it from opening too far.
Chains for exterior doors have a spring on each end for greater shock absorption than the stop for screen and storm doors. A vinyl cover protects the chain as well as surfaces from damage.
