The making of Tekiro wrenches 

TEKIRO wrenches are manufactured exceeding JIS standards. All are forged Chrome Vanadium steel precision machined, heat treated to extracting standards. They fulfill the needs of the professional engineer.
- Drop forged to ensure uniform grain structure, giving increased strength and reliability
- Heat treated in carefully controlled conditions to ensure optimum performance for every wrench
- Chrome nickel silver plated for maximum corrosion protection.
TEKIRO advanced ring configuration increases the contact area between the wrench and fastener, minimizing stress and reducing the chance of fastener damage.
