The finish decides
what survives outside.
A fastener fails from the outside in. The right surface treatment sets corrosion life, friction coefficient and cosmetic finish - before the bolt ever goes into service.
Choose the coating, not just the material
The base material and the coating are one system. Zinc-nickel and passivation buy salt-spray life; anodizing finishes aluminum; PVD and DLC set a low, stable friction coefficient that makes torque-to-clamp predictable. We match the treatment to the environment, the mating material and the assembly tool.
- Zinc-nickel and passivated stainless for high-corrosion service
- Anodizing for aluminum bolts, sleeves and cosmetic hardware
- PVD/DLC coatings for controlled friction and wear resistance
- Salt-spray and friction-coefficient testing tied to your spec
Environments we coat for
Outdoor & EV exposure
Corrosion-resistant coatings that survive humidity, salt and thermal cycling.
Medical & food gear
Passivated and cleanable finishes for hygienic equipment.
Precision & tooling
PVD/DLC finishes that hold torque repeatability on critical joints.
The coated families engineers ask for most
Surface treatment questions we hear most
Zinc-nickel on steel and passivated austenitic stainless lead on corrosion life; anodized aluminum suits cosmetic outdoor parts. We tie the choice to your required hours and mating materials.
Coating sets the friction coefficient, which sets how much clamp you get from a given torque. PVD/DLC gives a stable, repeatable value so assembly torque is predictable.
Yes - we run salt-spray, thickness and friction-coefficient tests and report results, so the release spec is verified, not assumed.
Need a finish that matches your environment?
Send the exposure, mating material and torque spec - we will specify the coating and back it with test data.
