💡 What steps keep small metric hex socket fasteners from rounding out during bike frame repairs?
Snap the exact driver bit into the recess before applying axial pressure to the bolt shank.
- Keep your tool roll handy by wiping metal shavings off the threaded shaft first
- Seat the recess flush against the housing so torque spreads evenly across both flanks
- Click the adjustable wrench until the preset limit trips to prevent drive deformation
- Swap out stripped drives quickly since a tidy stock keeps weekend builds rolling smooth
