Bolt SELMUL25
Mack

This high strength bolt is engineered to handle high load conditions typical of heavy duty suspensions, frames, or driveline assemblies. The SELMUL25 designation implies a specific grade and length suitable for resisting shear and tensile stresses while maintaining clamping force under vibration. The bolt's threads and head geometry are designed to facilitate secure tightening with common tools, promoting repeatable torque control and reliable assembly integrity during service. Its robust construction helps prevent loosening over time, reducing maintenance downtime and prolonging component life. Proper pairing with compatible nuts, washers, and lock methods ensures long term performance in demanding trucking environments. Source One Parts Center
