The 925-S139 Ag U-Bolt (1/2" x 2-5/8" x 11-1/2") Square is a medium-duty agricultural U-bolt built from cold drawn Grade 5 steel for strength, durability, and dependable clamping force. Designed with rolled fine threads for up to 30% greater strength, this square U-bolt delivers tighter nut retention and increased thread engagement thanks to its included Hi-Nuts. Precision tolerances ensure consistent fitment—because when it comes to holding components in place, close enough isn’t good enough.
