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.

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.

Features

Square nuts are used with flat washers to prevent damage from their sharp edges and improve the strength of the fastener.
They work well in restricted spaces when using pliers or wrenches, and are less likely to become rounded-off due to frequent loosening / tightening.
Square nuts have fine / standard / coarse threading and are available in plain, zinc clear, zinc yellow, tin and cadmium plating variants.
Raptor Supplies offers square nuts made of stainless steel, steel or Vinyl Ester Fire-Retardant Resin (VEFR), in thread sizes ranging from 1/2-13 to 10-24.
