Features

  • Grainger square U-bolts feature a square U-shape design, providing a stable and secure grip on cylindrical objects. They are equipped with threading and nuts, enabling easy installation and adjustment. These square U-bolts have flat ends to reduce the chances of damage or distortion to the fastened objects. These Grainger U-bolts are available in hot dipped galvanised, plain and zinc-plated variants for ensuring longevity even in harsh environments.
  • The brand's standard U-bolts feature aluminium / steel / stainless steel construction, ensuring high strength and durability for heavy-load applications. They have precision-rolled threads to enhance clamping force and reduce the risk of thread damage. These U-bolts provide a uniform distribution of clamping force for a secure and balanced hold. They are available in black oxide, hot dipped galvanised, plain and zinc-plated finishes for resisting corrosion on exposed surfaces.

Frequently Asked Questions

How do I properly install Grainger U-bolts?

  • Prepare the surface by ensuring it's clean and free from debris.
  • Select the right size U-bolt for the item and surface.
  • Position the U-bolt around the item with threaded ends facing outward.
  • Add washers and nuts onto the threaded ends.
  • Hand-tighten the nuts to hold the U-bolt in place.
  • Evenly tighten the nuts on both sides using a wrench.
  • Torque the nuts to specifications using a torque wrench.
  • Inspect the installation for alignment and tightness.
  • Make adjustments if necessary, carefully retightening as needed.

What are the differences between square U-bolts and standard U-bolts?

Square U-bolts are characterised by their square or rectangular shape with two parallel arms perpendicular to a straight base. They are used for securing square or rectangular objects like pipes, tubes or lumber to flat surfaces. On the other hand, standard U-bolts feature a U-shaped design with threaded arms at both ends. They have a semicircular bend and two threaded legs extending from the base. This design makes them versatile for securing round or cylindrical objects such as pipes, conduits, or cables to flat surfaces. Standard U-bolts are used in the construction, automotive and plumbing industries.

What factors should I consider while choosing these Grainger U-bolts?

Major factors include material, size, load capacity, thread type, surface finish, application environment and compliance requirements.
