SAF-Holland

A heavy-duty locknut rated for 7/8-9 inch threads, this Grade as part of trailer axle and suspension hardware delivers reliable locking performance in high-vibration environments. The prevailing-torque design helps prevent loosening during dynamic loads, braking forces, and rough road conditions commonly encountered in fleet operations. VMRS code 053-007-035 categorizes it with locking fasteners used in suspension and axle assemblies, aiding maintenance teams in stocking compatible kits and computing replacement intervals. Cross references such as TDA R302983 further assist technicians with substitution options within established catalogs. Category 42594 reflects its specialized role in securing critical joints that experience frequent movement and load shifts. In practice, this locknut supports consistent preload across mount points, enhances joint stability, reduces maintenance downtime, and contributes to safer, more reliable trailer and bus suspension performance throughout the service life of the vehicle.
