Square Nuts

Square nuts are four-sided nuts designed for use with a square head bolt & flat washer. They have a large surface in contact with the part being fastened and therefore, offer superior resistance to loosening. Raptor Supplies offers these square nuts from brands like Grainger, Dynaform, Fabory, Super-Strut and Unistrut.

Frequently Asked Questions

How do you know if a nut is left or right handed?

Nut handedness describes the way a nut's thread wrap around a shaft. Left-handed threads run counterclockwise, and right-handed threads run clockwise.

What are the benefits of using a square nut?

  • Easy to Tighten: They feature a four-sided shape for easy tightening. These nuts grip two opposite sides of the fasteners to tighten or loosen them.
  • Quick Gauge: They provide a quick visual gauge for easy checks and decreasing the risk of fastener failure.
  • Perfect for Blind / Tight Locations: They can be tightened using a wrench or pliers for use in blind locations. Users can tighten or loosen a square-shaped fastener without looking at it, once grip is obtained.

What are the differences between hex nuts and square nuts??

  • Hex nuts are easier to install and tighten than square nuts as they have more sides to provide more torque.
  • Square nuts need more space as they require wrench movement in a 90-degree range. On the other hand, hex nuts can be installed in smaller spaces as they require only 60-degree wrench movement.
  • Square nuts provide better protection against accidental loosening as compared to hex nuts. Square nuts usually cover a larger surface area to press against the object, thereby preventing their loosening.
