![Non-treated bolts [Contributing to a decarbonized society]](https://image.www.ipros.com/public/product/image/2cc/2000799595/IPROS76745102935338841948.jpeg?w=280&h=280)
Achieve CO2 reduction and cost reduction simultaneously. The CO2 reduction effect during production is up to 78%!
This is a non-heat-treated bolt suitable for a decarbonized society that allows for consideration of the global environment just by using it. By omitting the heat treatment, which requires the most energy during manufacturing, we are reducing CO2 emissions in the production process. Additionally, by eliminating the bending that occurs during quenching, we can skip the straightening process required for long bolts. This also achieves cost reduction by removing the bending correction process. Regarding the crucial aspect of strength, when used in high-strength applications, it shows improved delayed fracture characteristics compared to conventional heat-treated bolts. *For more details, please check the materials from "PDF Download" or feel free to contact us.*
