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. Here at Wentins, we have a selection of square nuts matching a variety of diameters, in stainless steel.
