Technology / product information

PC/BT is a hex head bolt made from polycarbonate (PC), designed and manufactured by Nippon Chemical Screw Co., Ltd.
This high-performance plastic fastener combines transparency, light weight, electrical insulation, and corrosion resistance, making it ideal for electronic equipment, automotive electronic components, food processing machinery, and chemical systems.

As a non-metallic alternative to conventional metal bolts, PC/BT offers non-magnetic, rust-free, and chemical-resistant performance.
It is particularly suitable for MRI-compatible applications, corrosive environments, and cleanroom systems where metal materials cannot be used.
