“Awesome company, quick lead times, great customer service. Latest order was 15 different parts using a variety of different steel and aluminum, some coated, one with countersunk holes, and they came in perfect. They even sent a sticker! Will definitely continue working with them on future projects and recommend trying them out if you’re looking to have some parts made”

Countersinking helps hardware sit flush

Increase the life of your hardware

Countersinking protects your hardware from long-term wear by allowing the head to sit flush against the surface of your part. Pair it with our hardware insertion services for full assemblies.
