Product Description

Chinese Manufacturer A2-70 A4-80 M20 M24 M30 M33 Stamping Square Nuts

A Square Nuts is a nut with four sides. Different to standard hex nuts, square nuts have a greater surface in contact with the part being fastened,and could provide greater resistance to loosening,though also greater resistance to tightening. They are also much less likely to become rounded-off after repeated loosening or tightening cycles. Square nuts are typically mated with square-headed bolts or screws. 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 can have standard, fine or coarse threaded with platings of zinc yellow, plain, zinc plated.and also will made of stainless steel which could provide good corrosion resistance in such hostile conditions.
