Channel Nuts & Hardware - Electrical Sector

1 Channel NutsChannel nuts are one of the main components of our strut system. It is designed to provide essential gripping powerand ease during installation. Channel nuts are press formed, machined and hardened from steel which meets therequirements of ASTM A108 or ASTM A36 for our larger , Screws, and NutsAll bolts, screws and nuts meet the physical and chemical requirements of ASTM A307, SAE J429 or ASTM A563, andhave unified inch screw threads (coarse, UNC). ISO metric threads are also available on special TorqueSpecial Note:For recommended torqueon 4 Dimension trapeze hangersusing B200 series square washers,see page & Finishes**Unless otherwise : Channel nuts are not available in HDG, Aluminum, or Stainless Steel Type 304 MetricMetric dimensions are shown in parentheses.
