Hexagon Head Bolts With Wire Holes

Hexagon head bolts with wire holes look like standard hexagon bolts, but there are several small holes drilled in its head. This way, wires or cables can be passed through multiple bolts. They are very easy to install and are often used in machinery, motorcycles or outdoor equipment, etc.

Features and parameters

Hexagon head bolts with wire holes have solved the problem that bolts remain tight in a high-vibration environment. By passing the steel wire through the holes of the adjacent bolts, a "lock" can be formed to prevent the bolts from loosening. This is cheaper and simpler than using special anti-loosening nuts or adhesives. They are used to fix bicycle parts, aircraft panels or engine components that shake frequently.

Hexagon head bolt with wire hole locking can be seen everywhere. Motorcycle brake calipers use them to ensure safety on rough roads; Aircraft maintenance personnel fixed the bolts to the maintenance panel with steel wire. Farmers use them on tractors to prevent components from loosening. Amusement park equipment also relies on them to prevent tampering.

For ship rigging or sailing ship hardware, hexagon head bolt with wire hole can withstand the invasion of seawater and storms. Pass the marine-grade steel wire through the bolt holes, and a fail-safe connection can be formed on the mooring piles, mast fittings or railings to prevent loosening.

Installing tips

Installing hexagon head bolts with wire holes requires two steps. First of all, they need to be tightened properly with a wrench. Then, pass the metal wire through the hole in a pattern (such as an "8" shape) that connects multiple bolts. Twist the two ends of the metal wire together with pliers to fix all the components in place. The use of crimping sleeves can make the surface neater.
