Square Nut
Square Nuts are four-sided nuts designed to provide a greater bearing surface compared to standard hex nuts. They are manufactured to ASTM and DIN standards and are available in standard, thin, and heavy-duty forms. The square profile reduces the risk of rounding and allows better grip during tightening and loosening. They are often used with square-headed bolts, carriage bolts, and in timber or metal structural applications. Square Nuts are widely used in railways, construction, furniture, machinery, and restoration of vintage structures.
