tight tolerances
Whether you are in the elevator industry, aerospace, automotive, telecommunications or electronics, our precision metal stamping services can deliver the part shapes you require. Our suppliers work hard to meet your tolerance requirements by iterating tool and die designs to fine-tune output to meet your needs. However, the tighter the tolerances, the more difficult and costly it is. Precision metal stampings with tight tolerances can be brackets, clips, inserts, connectors, accessories and other parts in consumer appliances, power grids, aircraft and automobiles. They are also used to make implants, surgical instruments, temperature probes and other medical device parts such as housings and pump components.
Regular inspection after each successive run to ensure the output is still within specification is typical for all stampings. Quality and consistency are part of a comprehensive production maintenance program that monitors stamping tool wear. Measurements using inspection jigs are standard measurements on long-running stamping lines.

Product introduction
The process of brass round head hexagon socket bolts mainly includes the following basic steps:
1. First, you need to select a brass material that meets the requirements. Brass has excellent processing properties and corrosion resistance, making it suitable for making bolts. When selecting materials, factors such as the bolt's strength, corrosion resistance, and usage environment need to be taken into consideration.
2. After selecting the material, proceed to the forging or forming process. This step mainly uses mechanical force or pressure to process the brass material into the basic shape of the bolt. For round head hexagon socket bolts, you need to ensure that the head is round and the interior is a hexagonal structure.
3. After forming, thread the bolts. This usually involves using a thread-cutting tool, such as a thread turning tool or thread milling cutter, to create threads to standard.
4. After the threading is completed, heat treat the bolts. This step is mainly to improve the hardness and strength of the bolt, while eliminating internal stress to ensure that the bolt has stable performance during use.
5. As needed, perform surface treatment on the bolts, such as cleaning, polishing or coating with anti-rust oil, to improve their appearance quality and corrosion resistance.
6. Finally, perform quality inspection on the bolts to ensure that they comply with relevant standards and requirements. After passing the inspection, it is packaged for transportation and storage.
During the entire process, we control the process parameters and quality requirements of each process to ensure that the final produced brass round head hexagon socket bolts have good performance and quality. At the same time, it is also necessary to pay attention to production efficiency and cost control to meet market demand and economic benefits.
