Frequently Asked Questions

Are these hexagon bits suitable for saltwater environments?

Yes, the hardened steel bits feature a corrosion-resistant phosphate finish, making them suitable for regular use in marine and offshore conditions. However, we recommend wiping them clean and applying a light oil after exposure to seawater to extend their lifespan.

What types of drivers are compatible with these bits?

The bits have a standard 1/4" hex shank, so they fit all common hex bit holders, screwdrivers, and power tools with a matching chuck.

Do the sets include both metric and inch sizes?

Yes, this set provides a range of both metric and fractional-inch hex sizes to cover the majority of maintenance tasks on board.

Can these bits be used with impact drivers?

The bits are hardened to resist wear and are suitable for manual and power drilling/driving. For heavy-impact applications, we recommend checking the specific bit condition and using appropriate personal protective equipment.
