Plastic Dowel Pins
Plastic pins are a nonconductive and nonmagnetic alternative to metal dowel pins, so they're useful in electronic applications. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.
Acetal plastic and PTFE plastic pins are slippery, so they make excellent pivots. Acetal pins resist wear.

Screw-Mount Locating and Support Buttons
Mount through the counterbored hole with a socket head cap screw to support and position workpieces and fixtures from the bottom or side. They’re also known as rest buttons.
For technical drawings and 3-D models, click on a part number.
Spring-Loaded Guide Pins
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.
Plastic-head pins won't mar soft metal and polished surfaces.

Inspection and Measuring Fixturing
Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with 1/4"-20 holes. They are not for use in machining applications.
