Square U-Bolt, 5/8" X 4" X 5-1/2"

The 925-S1050Z Square U-Bolt is a heavy-duty agricultural square U-bolt built for secure clamping on larger mounts, axles, and square tubing applications. Made from cold drawn Grade 5 steel with rolled fine threads and nuts included, it’s designed for strong thread engagement and a tight, reliable hold—because when you’re fastening something this size, “snug” needs to stay snug.
