기능

• Nylon is attached to the top of the hexagonal nut, and the nylon part generates the prevelling torque, and the frictional resistance produced by the prevelling torque produces the anti-loosening effect.
• Material is steel with UNIQLO plating (light blue color) for improved corrosion resistance.
• This is an original product of Hachiman-thread with reliable quality and price.
• Used for tightening, fastening and fixing the external thread.
• Has an anti-loosening effect.
• Has more corrosion resistance than fabric.
