TM Daclo treatment high strength bolt
Tsukimori Industrial Co., Ltd.
About This Product
■Exhibits high corrosion resistance, high heat resistance, and excellent rust prevention ability.
Dacro treatment involves coating high-strength bolts by dipping them in a dacrotized treatment solution, and then heat-treating them in a baking furnace at 270°C to 330°C to create excellent rust prevention ability. The finished appearance is a beautiful silver-white dacro coating.
■Features
・There is no hydrogen embrittlement, so there is no concern about delayed fracture.
・Torque coefficient value is stable by applying special surface lubrication treatment to the nut.
・When applying a top coat, it is possible to color the product by using the appropriate paint, and it has excellent adhesion with the paint.
■Robust, flexible and stable quality
To ensure stable axial tightening torque, we conduct temperature dependence experiments under harsh conditions of 0 to 60°C for quality control. In addition, we enhance product reliability through strict process control that meets accuracy requirements of 1/100 to 1/1,000 mm.
