Cold heading Service


Ningbo Teng Qi Fasteners Co., Ltd is a leading customized bolts manufacturer in China. Customized bolts are bolts that are specifically designed and manufactured to meet unique or specific requirements of a particular project or application. These bolts can be tailored in terms of their size, shape, material, threading, head style, and other features to ensure they fit perfectly and perform optimally in a given situation.

Customized bolts are often used in industries where standard off-the-shelf bolts may not suffice due to factors such as size constraints, environmental conditions, load-bearing requirements, or other specialized needs. We have the capability to create customized fasteners to exact specifications.

FAQ about customized bolts:

1.How do I specify the required customization?

We need detailed specifications, including drawing noted dimension and tolerance, materials, and tension strength, surface treatment.

2.What is the lead time for manufacturing customized bolts?

Lead times depends on the order quantity, and the complexity of the products. We need drawings to plan the production process to see if the bolts need to be machined or can be formed directly with a multi-station cold header. Total lead time=material purchase time + mold manufacturing time + production time (cold heading or hot forging + machining time + heat treatment + surface treatment + packing)

3.Can I get samples before ordering a large quantity of customized bolts?

Yes, we can offer samples to ensure the bolts meet your requirements before a full production run.

4.Can I order customized bolts in small quantities?

It is a little hard, our MOQ is about 1ton for customized bolts. Any it depends on detailed products, welcome to send your requirement to our email:

5. What testing and quality control measures are typically performed on customized bolts?

We control quality strictly, such as tensile testing, hardness testing, and dimensional inspections, to ensure they meet quality standards.
