Countersinking thin sheet? The countersink calculator shows the hole you'll get on the back of the part and whether you need an undercut screw.

Are there limitations on the material thickness for countersinking?

We can perform countersinking on most thicknesses of metals. However, the material's properties may influence the final outcome, and we advise consulting with us for the best approach for your specific material.

Do you offer deburring?

Absolutely! At Fabworks, we provide deburring and finishing services at no additional cost to our customers. This process is an integral part of our commitment to delivering high-quality, precision-cut parts.
