💡 What makes square cut drive locks safer than round wedges for high torque applications?

Folks mostly run this hardware because flat mating surfaces spread shear force evenly along the axle face.

- Straight geometric profiles stop sideways slip that shatters weak pinion teeth during muddy trail crawls.

- Matched width tolerances clamp shafts tight so engine vibration never cracks stiff aluminum casings over seasons.

- Simple slide fit layout saves greasy knuckles when swapping busted units for fresh replacements on remote job sites.
