T-LSB (T-Nut Lag Screw Bolt) is a product developed to simplify construction and reduce costs as a component for fastening steel plates and wood materials such as CLT. It demonstrates significant effectiveness in the construction of composite structures involving wood-to-wood, wood-to-steel, and wood-to-steel-to-RC components. 【Features】 - There is no hexagonal head like traditional LSBs, so counterboring of the wood is unnecessary. - Since there is no counterboring, the epoxy resin filling work is not required. - Chiseling work, which is done when using fillers, is not necessary. - It can be easily screwed in using a dedicated attachment bolt. - Costs can be reduced by eliminating counterboring processing fees, filler costs, and chiseling work. - Simplifying construction can shorten the construction period. - Management is conducted for each manufacturing lot, and inspection reports are provided. ◎ For more details, please refer to the PDF document or feel free to contact us.

"TONEJI SUPER COAT" The high corrosion-resistant D-LOCK, enhanced with a unique top coating on a molten zinc-tin alloy plating, has arrived. We conducted a 5,000-hour salt spray test (JIS Z 2371) assuming use in salt damage areas, and no red rust was observed, while the occurrence of white rust was minimized. Additionally, we performed a CASS test (ASTM B368-21) for 625 hours as an even more rigorous examination. Please make use of this for rust prevention measures in heavy salt damage areas. ◎ For more details, please refer to the PDF document or feel free to contact us.

The "Shako Man Hug" is a specialized mounting fixture designed to fix the position of the column and backing plate when attaching the backing plate to the column. The Shako Man is a vice-like tool that clamps onto the edge of steel materials, but the "Shako Man Hug" is specifically tailored for backing plate attachment, making it user-friendly and expected to improve work efficiency. 【Features】 - By adopting a uniquely shaped plate, it allows for efficient and easy support work. - It uses a proprietary product called "HugBolt" for the bolt section, enabling smooth attachment due to its large thread pitch. - The R-shaped handle balances ease of tightening with reduced strain on the wrist. - It can accommodate column plate thicknesses of up to 36mm.

"Hug Bolt" is a temporary assembly bolt for steel structures that excels in workability and contributes to environmental and cost reduction. This product improves workability by significantly increasing the pitch of the threads, the angle of the thread peaks, 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 time resources remain on construction sites, reduce environmental impact, and enhance environmental conservation awareness. 【Features】 ■ Doubles the thread pitch of standard products to speed up work ■ Changes the thread angle to 90 degrees and modifies the tip to a rounded shape for suitability in reuse ■ Displays size on the bolt head to improve usability ■ Features a thick shaft structure that meets axial shear force requirements ■ Reduces disposal costs and contributes to an eco-friendly society through the application of the reuse plan *For more details, please refer to the catalog or feel free to contact us.
