Bolt & Nut, Japan, Takenaka Seisakusho
Takenaka Seisakusho ELE CUT Coating Bolt (Insulating Bolt)
Import from: Japan
Manufacturer: Takenaka Seisakusho
ELE CUT Surface Treatment
In a high voltage atmosphere, products having high insulating performance are needed. ELE CUT Coating bolt has high insulation and high corrosion resistance by a combination of various anticorrosive bolts and insulating materials (insulation sleeve and insulation washer). Anticorrosive bolts are selectable from TAKECOATⓇ-1000, TAKECOATⓇ-CERAMIC1,and DACROTIZED depending on the required anti-corrosive performance. Applicable to all materials, including double-ended bolts and hexagon bolts.
