Square Nuts

A square nut is a four-sided nut. Compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening (though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Square nuts are typically mated with square-headed bolts. Square nuts are used along with flat washers in order to avoid damage from its sharp edges and helps to increase the strength of the fastener.

Square nuts are four-sided nuts as opposed to the more common hex (six-sided) nuts. The surface area on the flats is larger than hex nuts, which reduces wrench slippage. However, you cannot use hex drivers such as sockets and nut drivers. Machine screw square nuts are available in smaller sizes and also smaller in width and thickness than regular square nuts. Machine screw square nuts have flat tops and bottoms—the edges and corners are not chamfered (beveled). Regular square nuts have a flat bottom bearing surface and a crowned washer-faced top. Regular square nuts are often used with square bolts.

Threads are standard right-hand and Unified inch coarse series (UNC, Unified National Coarse) or Unified inch fine (UNF, Unified National Fine).

Square Nut Regular Square nut size refers to its nominal thread diameter. Typically, machine screw sizes range from about #2 to 1/2" and regular from 1/4" to 1 1/2". Sizes less than 1/4" appear as a number size (the larger the number the larger the size) while sizes that are 1/4" and larger are specified in inches, usually fractional rather than decimal.

Nut width, which is wrench size, and thickness vary with the size of the square nut. Table 1 lists width across flats and across corners, and thickness for machine square nuts; refer to Table 2 for dimensions of regular square nuts.

Steel, zinc plated, is a common material and finish.

Refer to ASME B18.6.3 for specifications relating to machine screw square nuts and ASME B18.2.2 for regular square nuts.
