Spring Clamp Workholders

Secure small parts in spring clamps to keep hands free for soldering, gluing, and assembly. The workholder’s arms are mounted to a base and adjust for positioning work at almost any angle.

Spring-Loaded Guide Plungers

As the face of these plungers is pushed in, their internal spring applies outward pressure to hold a workpiece in position against stops and rails. They’re also known as spring stops. These plungers make it easy to insert parts into your fixture or remove them, and they allow for slight variations in size from part to part. Mount them on flat surfaces.

Round Face


Triangular Base	Rectangular Base

Round face plungers hold curved and contoured surfaces.

Acetal Face—An acetal face is nonmarring to protect soft metal and polished surfaces.

Steel Face—A steel face is strong and wear resistant.

Stainless Steel Face—Choose a stainless steel face for chemical and corrosion resistance.

Spring Locating Pins


Zinc-Plated Steel Head	Acetal Head

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). Also known as spring locating pins and side-thrust pins.

Acetal Head—Acetal-head pins won't mar soft metal and polished surfaces.

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.

Spring Locating Pin Installation Tools

For Press-Fit Pins

For Screw-In Pins

Use these tools for easier locating pin installation.

For Press-Fit Pins—Tools for press-fit pins slip over the head of the pin to let you press or hammer it into place.

For Screw-In Pins—Tools for screw-in pins slot into notches on the side of the pin body to help you twist it into place.

Create-Your-Own Spring Locating 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).

Sealed Spring Locating Pins

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).

Stainless Steel Head—Stainless steel pins are a good choice to avoid corrosion when working with stainless steel workpieces or fixtures.

Threaded Spring Locating 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.
