A Boom Pin is used for connecting the boom to the upper frame. This allows the boom to be raised and lowered, and to move from side to side. The boom pin assembly transfers forces between the boom and the upper frame. This allows the boom to support the weight of the bucket and the material being excavated.

Attributes:
• Heat Treated with Rockwell Hardness of scale C48 which gives excellent strength
• Manufactured to precise specifications and is built for durability and reliability

Applications:
A Boom Pin acts as the primary pivot point for the boom, enabling it to swing up and down smoothly.
