It is commonly used in conjunction with bolts or screws to secure two or more components together. The square shape provides a larger bearing surface compared to a regular hexagonal nut, which can distribute the load more evenly and prevent the nut from rotating easily, especially in applications where there is significant vibration or torque. Square nuts are widely used in machinery, construction, automotive, and other industries. <a href=\"https:\/\/www.china-nut-factory.com\/nuts\/square-nut\/\">Square Nut<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.china-nut-factory.com\/uploads\/46492\/small\/high-strength-structural-nuts06bb9.png\"><\/p>\n<h4>1. <a href=\"https:\/\/www.china-nut-factory.com\/\">Jiaxing Jinling Hardware Technolgy Joint Stock Co., Ltd.<\/a><\/h4>\n<p>Jiaxing Jinling Hardware Technolgy Joint Stock Co., Ltd. is a well &#8211; established enterprise in the hardware manufacturing field.
