DIN577 Square Nut

Square Nuts Product Describsion

Square Nuts are Boltead’s main product. We are a manufacturer and also a supplier of these nuts. While producing and supplying these nuts, we also produce bolts, washers and other fastener products used in conjunction with them.

The square nuts  we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:

Carbon steel square nuts are generally classified according to strength levels. The more common strength levels are: 4, 8, 10, and 12. Among them, nuts with grade 8 or above are generally called high-strength nuts（high tensile nuts）.Stainless steel square nuts are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316

In addition to different materials and strengths, the biggest impact on these nuts is surface treatment. The following are the more common surface treatments for these nuts: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

Square Nuts Production Process

Square nuts are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:
