DIN975 Threaded Rod

Threaded Rod Product Describsion

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

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

Carbon steel threaded rods are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, threaded rods with grade 8.8 or above are generally called high-strength threaded rods （high tensile threaded rods）.Stainless steel threaded rods 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 the product is surface treatment. The following are the more common surface treatments for threaded rods: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

Threaded Rod Production Process

Threaded rods 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:

Threaded Rod Application fields

These threaded rods are versatile and can be used in many different situations where a secure and durable fastening solution is required.
