Flange nuts are used when a standard hex nut needs more bearing area under the nut face. The built-in flange spreads load over a wider surface and can reduce the need for a separate flat washer in many assemblies.<\/p>\n\n\n\n
For buyers, the main question is simple: does the flange nut improve the joint, or is it only being used out of habit?<\/p>\n\n\n\n
A flange nut is a hex nut with an integrated washer-like base. The flange can be smooth or serrated.<\/p>\n\n\n\n
Smooth flange nuts are used where a larger bearing face is needed. Serrated flange nuts add biting action against the mating surface, which can help resist loosening in light to moderate vibration.<\/p>\n\n\n\n
Buyers reviewing industrial \u0111ai \u1ed1c<\/a> should confirm the flange type, thread, grade, material, and finish before comparing prices.<\/p>\n\n\n\n Flange nuts are widely used in:<\/p>\n\n\n\n They are often paired with bolts, studs, and screws from \u1ed1c v\u00edt ti\u00eau chu\u1ea9n<\/a>.<\/p>\n\n\n\n The flange spreads pressure better than a narrow hex nut face. This helps reduce surface indentation, especially on slots, thin plates, and softer materials.<\/p>\n\n\n\n In many cases, one flange nut can replace a nut and washer combination. This reduces handling time and lowers the chance of missing washers during assembly.<\/p>\n\n\n\n Serrated flange nuts can improve grip, but they are not a complete solution for severe vibration. Critical joints may still need torque control, thread locking, prevailing torque nuts, or engineered locking washers.<\/p>\n\n\n\n Tr\u01b0\u1edbc khi \u0111\u1eb7t h\u00e0ng, h\u00e3y x\u00e1c nh\u1eadn:<\/p>\n\n\n\n For metric specification checks, this H\u01b0\u1edbng d\u1eabn ti\u00eau chu\u1ea9n chi ti\u1ebft si\u1ebft ch\u1eb7t DIN v\u00e0 ISO<\/a> can help avoid unclear substitutions.<\/p>\n\n\n\n Do not use serrated flange nuts on finished cosmetic surfaces unless marks are acceptable.<\/p>\n\n\n\n Do not assume a flange nut always replaces a washer. Large holes, soft materials, or special bearing requirements may still need washers.<\/p>\n\n\n\n Do not mix nut grades with high-strength bolts without checking compatibility.<\/p>\n\n\n\n For unusual dimensions, special flange sizes, or drawing-based parts, \u1ed1c v\u00edt t\u00f9y ch\u1ec9nh<\/a> c\u00f3 th\u1ec3 \u0111\u01b0\u1ee3c y\u00eau c\u1ea7u.<\/p>\n\n\n\n\u1ee8ng d\u1ee5ng ph\u1ed5 bi\u1ebfn<\/h2>\n\n\n\n
