Square Nuts

What are Square Nuts?

Accu Square Nuts are designed to be used alongside screws and bolts to create secure fastenings. Square Nuts have a larger surface contact area than Hexagon Nuts, making them more resistant to loosening. Square Nuts are often used in conjunction with Washers to prevent any damage caused by the edges of the nut.


Components within this range can be manufactured from both A2 and A4 Stainless Steel, as well as Aluminium, Brass, Phosphor Bronze and PEEK. Chemical Matte Black Coatings can also be applied to Stainless Steel Components on request.
