U-Bolts

U-bolts are used to support heavy objects from walls, poles and ceilings. Raptor Supplies offers a wide range of U-bolts from brands like Grainger, Anvil, ZSI, Chicago Hardware and Calbrite. The U shape of these bolts keeps them firmly in place, providing stability to the support.

Frequently Asked Questions

What are U-bolt nuts made of?

These nuts are made of steel / stainless steel / aluminium / polyurethane rubber, ensuring high impact and abrasion resistance.

What is the significance of nonconductive U-bolts?

These fibreglass-reinforced polyurethane U-bolts do not conduct electricity and prevent metal-to-metal corrosion. These U-bolts are chemical, UV and abrasion resistant.

What accessories are compatible with these U-bolts?

Standoff brackets can be used with U-bolts for conveying pipes, tubes and cable raceways at a distance from walls, floors and ceilings. They offer extra clearance that allows access for maintenance as well as adding & removing lines.

How do we measure the size of a U-bolt?

The length of these fasteners is measured from the bolt end to the inside of the bends. The width of these U-bolts is measured between the legs.

What mounting options do these U-bolts offer?

These U-bolts offer threaded / screw mounting for easy and secure installation.

What types of nuts can be used with U-bolts?

U-bolts are compatible with hex nuts, nylon-insert lock nuts and serrated flange lock nuts.

How to install U-bolts?

  • Remove both nuts from all sides of the U-bolt.
  • Place the U-bolt around the pipe to be attached and thread the ends of the bolt through the holes in the supporting beam or structure.
  • Thread all the nuts on each of the bolt's outer ends.
  • Tighten the nuts that are closest to the support beam manually.
  • Finally, tighten the outer nuts on ends of the U-bolt with a wrench or an influence tool.

What safety precautions should be taken while using U-bolts?

  • Before using, check for damages that may be caused due to the high pressure exerted while pulling a load with a truck.
  • Tighten the nuts if loosen to prevent slipping.
  • Replace the U-bolt if any crack is found.
  • If the U-bolt is rusted, get a new one.

How do I determine the right size of U-bolt for my application?

You can determine the right size of standard U-bolts by measuring the diameter of the steel bar or pipe you need to attach and selecting a U-bolt that matches or slightly exceeds that diameter.

When should I use square U-bolts?

Square U-bolts are used in applications where there is a need for greater stability and resistance to movement or rotation. They are ideal for securing items with square or rectangular shapes, such as lumber, beams, poles or frames. Square U-bolts provide a more secure grip, minimising the risk of shifting or slipping.
