While our Modular Vise System is designed to work exclusively with our standard fixture plate hole patterns, we understand that customers may have a different fixture plate or otherwise want to integrate the Mod Vise into their fixtures or machines. The below drawings give the minimum requirements for mounting and using each version of the Mod Vise so that you may verify compatibility with your own fixture plate or use this information to create your own fixture. The given hole locations and spacings are required for mounting the vise. Fixture plates with different thread sizes but the proper hole locations are generally not recommended and will require sourcing your own mounting hardware. 1/2" Vise: (save as PDF) M12 Vise (not to scale): (save as PDF) 1/4" (Hobby) Vise (save as PDF) M6 (Hobby) Vise (save as PDF)*note: older 1/4" and M6 fixture plates and fixturing pins used an 82-degree countersink angle. For compatibility for non-US customers both were changed to use a 90-degree countersink. Due to the relatively small contact area, our testing has shown no difference when using an 82-degree pin with a 90-degree fixture plate or vice versa.
