Qimao Metal Manufacturer provides quality Aluminum Shoulder Pin For Automotive Horn Positioning And Assembly made in China. An aluminum shoulder pin is basically a small metal pin with two different diameters. The wider part is called the shoulder. It stops the pin from going too deep into the hole. It slides into the housing first, and the shoulder makes sure everything stops at the right position. Then workers can put the rest of the horn together without anything shifting around.
1-Two diameters in one piece. The smaller end goes into the hole. The wider shoulder stops it at the right depth. No guess work during assembly.
2-Aluminum raw material. We use aluminum because it's light. Car makers don't want heavy parts. But it's still strong enough for horn assembly, for the horn the aluminum material is enough to match.
