기능

• The bending part adopts WISE's original hot bending method.
• Heating during bending prevents the material from becoming uneven and maintains the highest level of strength while maintaining toughness.
• Special alloy steel is used as the material to ensure homogeneity and the highest accuracy of hardness.
• Completely oxidation-free and decarburization-corrected quenching type heat treatment using a closed furnace is performed.
• It is very strong and the corners are hard to be pulled.
• The length of the small L corner has been cut down to the extreme so that it can be inserted even in small or deep places.
• Suitable for tightening bolts with hex holes in narrow or deep places.
