Wrench tolerances

Precision work for perfectly fitting nominal dimension

HAZET wrench – high precision tightening
Tolerance achieved by HAZET
and loosening of screw connections
• Long service life due to:
– High-quality chrome vanadium steel
– Compacted material structure from drop forging
– Careful heat treatment
– Correct hardness and dimensional stability as
guarantors of wear resistance and high load capacity
• Shape, dimensions and surface design are perfectly
coordinated to one another which guarantees functional
Permissible tolerance in accordance with DIN standard
handling and meets ergonomic requirements
• Slim construction through optimum material
composition guarantees sufficient freedom of movement
even with hard-to-reach screw connections
• HAZET torque values are considerably higher
than the DIN ISO requirements for all wrench
sizes – here DIN is the minimum requirement
• Slim open-end and box-end head shape does not reduce
HAZET HAZET the wrench’s loading capacity, although this is well below
the maximum permissible limit value according to DIN ISO
