Improved work speed with a large screw pitch! This is a temporary fastening bolt that is less prone to dents and suitable for reuse.
"Hug Bolt" is a temporary assembly bolt for steel structures that excels in workability and contributes to environmental and cost reduction. This product enhances work efficiency by increasing the pitch of the threads, the angle of the thread flanks, and the lead of the thread tip compared to conventional products, allowing for smooth rotation from the initial engagement of the bolt and nut. Additionally, its design minimizes the likelihood of dents on the threaded section, making it suitable for reuse. This reduces disposal costs and contributes to an eco-friendly society. Furthermore, as part of the recent efforts in construction sites to challenge zero emissions, we have devised a reuse plan for Hug Bolt. This initiative aims to shorten the resource retention time at construction sites, reduce environmental impact, and raise awareness of environmental conservation. 【Features】 ■ Doubles the thread pitch of standard products to speed up work ■ Changes the thread flank angle to 90 degrees and modifies the tip to an R shape for suitability for reuse ■ Displays size on the bolt head to improve usability ■ Features a thick shaft structure that meets axial shear force requirements ■ Reduces disposal costs through the application of the reuse plan, contributing to an eco-friendly society *For more details, please refer to the catalog or feel free to contact us.
