Bolt Size: M5x11mm
Oxygen-free copper washers and special processing have improved conductivity to reduce the generation of static electricity which is resistant to movement of objects.
Use as a bolt for securing wires in the positive and negative terminals of the battery.
Batteries on cars and motorcycles are made of galvanized steel except for expensive products.
The electricity produced by the generator will flow into the battery and be charged.
If all power generated is used to charge the battery, then this is no problem.
However, the terminals with the aforementioned structure are resistant and trace amounts, but the electricity is dispersed into each part of the vehicle instead of the battery.
Dispersed excess electricity remains in place when it reaches hard to conduct electricity, such as plastic parts, rubber parts, glass and more. Any remaining electricity is unmovable or "static".
Oxygen Free Copper Washers and Special Treated and Improved Conductivity Bolts can also be seen in products intended to reduce electrical resistance and increase charge and discharge efficiency, but the true purpose is for years to come.
When excess electricity is reduced, you can see how much the vehicle changes and attach only 2 bolts (3 if installed on the earth point) and feel the moment you run out.
