Fastening components used for various joints utilizing wooden materials. For all types of fastening in wood-steel hybrid structures and RC members, etc.
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.
