Threaded Locating and Support Buttons
Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket. Threading makes these buttons easier to replace than press-fit, so they are a good choice for high-wear applications. They’re also known as rest buttons.
