​Online Countersinking Services
Our online countersinking service is designed to increase the life of your hardware and ensure that your parts are clean and high-quality. Countersinking is a machining process that creates a conical hole in a part so that a screw or bolt can sit flush with the surface.
By using countersinking, you can reduce stress on your hardware and prevent it from becoming damaged or corroded over time. This makes your parts more durable and reliable in the long run.

What to expect from your countersunk parts
Parts may have oil/lubricant residue on the surface
Some light deburring may be required by the customer to remove sharp edges left by the countersinking process
​Parts will not have a perfectly machined finish. Some scoring is expected.
Powder coating will add .003”-.005” (.076mm-0.13mm). We’ll adjust the hole size to account for this, but keep in mind that the fit may be tight on countersinks with powder coating
