5/16"-18 x 1.3125" x 1.75" Square U-Bolt

A sprayer boom takes a beating on every pass across rough ground. This square U-bolt wraps around the square boom tube and bolts through predrilled holes, so the parts it holds stay put. When an old U-bolt rusts, bends or strips, the boom starts to shift, and this OEM replacement puts the connection back where it belongs.

It fits FIMCO 4, 5 and 7 nozzle booms with 1 inch square tube, and it is made from galvanized steel for strength and durability. A loose boom wears the parts around it, so swapping a worn U-bolt early costs far less than repairing what it damages.

Highlights

• Clamps tight around a 1 inch square boom tube
• Fits FIMCO 4, 5 and 7 nozzle booms with 1 inch square tube
• OEM replacement part
• Galvanized steel for strength and durability
• Warranty: 1 yr Consumer, 90 day Commercial

What it's for

Use it when a U-bolt is rusted, bent or stripped, or when you are servicing the boom mount before a busy season. Doing it before spray day keeps you from stopping in the middle of a field.

It suits the sprayer owner spraying a lawn, a pasture or a field edge, the groundskeeper who runs more than one sprayer, and the farm hand who keeps the rig ready for the next job.

At a glance

How to use it

1. Empty the tank, relieve the pressure, and shut off the sprayer before you work on the boom.
2. Remove the worn U-bolt and its nuts, then check the boom tube for cracks or wear.
3. Fit the new square U-bolt around the square tube and through the predrilled holes, and hand-tighten the nuts before you snug them evenly.
4. Compare the new U-bolt to the old one before you finish the fit.
5. Run water through the system and check the boom for movement before you spray.

Good to know

• Snug the nuts evenly, a turn at a time, so the U-bolt seats square.
• Check the U-bolts and nuts every time you service the sprayer.
• Keep a spare U-bolt in the shop so a broken part doesn't stop a spraying day.
• Pair it with 5/16-18 serrated flange hex nuts and the rest of the boom hardware from the same aisle.
