ACL Anti-galling Clamps

Safety Gate, Eye-Bolt & Nut

One of the problems in the industrie is the galling of hygenic clamps, with this clamp that problem is solved. 

The Safety Hex Nut Clamp is based around the design principal of the standard SH safety clamp. This new variation benefits from the added safety feature of a hex nut replacing the wing nut. Using the hex nut guarantees that the clamp cannot be loosened by hand. The nut is made from Nitronic 60 (Alloy 218, UNS S21800) known for its excellent galling resistance, even at elevated temperatures and low temperature impact resistance.

As Nitronic 60 is more resistant to this mechanism of wear, there is less particulate generated by on / off cycles. This makes the anti-galling clamp a perfect solution for clean room environments. In addition to the reduction of galling, end users can also have a ‘cleaner’ product.
