Channel Nuts With Springs .............................. 78 Channel Nuts Without Springs ........................ 79 Top Retainer Nuts .............................................. 79 UNISTRU T UNIST RU T
MATERIAL Unistrut channel nuts are manufactured from mild steel bars, and after machining operations are completed, they are case hardened, assuring positive biting action into the inturned edge of the Unistrut channel. The standard channel nut conforms to ASTM A576 GR 1015 modified and A1011 SS GR 45. Screws conform to SAE J429 GR 2 (also meets and exceeds ASTM A307).
FINISHES Nuts, bolts and washers are electro-galvanized (EG), ASTM B633 Type III SC1 finish, unless otherwise noted. Many hardware items are also available in stainless steel. Consult factory for ordering information.
