136501 - Silicon Bronze Nut Square- 5/16-18" UNC

A four sided square nut, with bevelled corners on one face.  The four sides provide a greater contact with the parent material, the potential to apply greater torque and reduce risk of rounding the corner during tightening that may occur on hexagonal nut.  

With an old fashioned aesthetic, these are perfect for traditional woodwork, wooden boats, classic cars/trucks restoration, bespoke classical furniture feature and used as a blind nut.
