We can accommodate both additional processing of commercially available bolts and custom manufacturing.
At Sun-Ei Co., Ltd., we offer custom-made screws tailored to specific products and specifications for applications such as construction, machine tools, transportation machinery, industrial machinery, and chemical plants. If you have any special screws that cannot be obtained commercially, please feel free to consult us. The "special air hole bolt" is used in vacuum devices when gas release is necessary, featuring a through hole to allow air to escape between the main body of the device and the screw. We can accommodate both modifications of commercially available bolts and custom manufacturing. We can also produce long bolts. For more details, please contact us or refer to our catalog.
