Square Nut - Overview

 

 

A square nut is a four-sided fastener with a flat bearing surface and a chamfered, washer-faced top. It's used with square-headed bolts and is known for providing greater resistance to loosening and rounding off compared to hex nuts due to its larger contact surface. Square nuts are often used in furniture, slotted applications, and where greater resistance to vibration is needed.

Advantages of Square Nut

 
 
01
 

Protection From Loosening

Square nuts are better protected from loosening than hexagonal nuts. Loosening involves a nut working its way off the bolt to which it's attached. You can attach hexagonal and square nuts alike by twisting them onto the end of a bolt. square nuts cover more surface area of the objects with which they are used, so they are better protected from loosening.

 
02
 

Easier to Keep Track

You'll have an easier time keeping track of square nuts than hexagonal nuts. You may accidentally drop a bolt or nut, only to watch it roll away into the abyss where you're unable to retrieve it. Square nuts aren't round. If you accidentally drop a square nut, it will typically stay in place. This makes square nuts easier to keep track of.

 
03
 

Wrench Tightening

You can tighten square nuts using a standard wrench. Hexagonal nuts support wrench tightening as well, but with six sides, you may struggle to grip them with a wrench. Square nuts have fewer but larger sides. As long as you have enough space, you should be able to easily place a wrench around two of these sides so that you tighten the square nut.

 
04
 

Available in a Variety of Styles

Square nuts are available in a variety of styles. They all feature a square shape consisting of four sides of equal length. With that said, some square nuts feature different characteristics than others.

FAQ

 

Q: What are square nuts used for?

A: Known as square nuts, they are used in conjunction with a bolt to hold two or more objects together. Square nuts have the same threaded interior as their hexagonal counterparts. They feature internal threading that supports the external threading of a bolt. The difference lies in their shape.

Q: What does a square nut look like?

A: Square nuts are similar in function to hex nuts, but are 4-sided instead of 6-sided. This shape increases the contact surface, which can help to prevent loosening in certain applications.

Q: What socket for square nut?

A: 8 Point 1/4" Socket Used (for Square Nuts)

Q: What is the result of using a cage nut with a square hole?

A: Cage nuts allow users to mount any type of rail or shelf into square hole racks. Being able to have a standardized square hole for server racks improves compatibility and makes things easier to repair.

Q: What is the difference between square and hex nuts?

A: Hex nuts are easier to install and tighten than square nuts. They have six sides, whereas square nuts only have four sides. Because they have more sides, hex nuts offer more torque, which makes them easier to install and tighten. You can install hex nuts in smaller spaces.
