Urrea wrenches are manufactured under ASME B107.100 specifications and incorporate the UGS system on all open-ends. UGS system was designed and patented by Urrea, which offers the following benefits: If a nut or a bolt’s edges are stripped, the 3-point contact distribution ensures that there is enough not contact to tighten or loosen. When torque is applied, the force is distributed to three points, thus reducing stress on the nut or bolt edges.
Included metric sizes: 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, and 21 mm. The combination mechanical wrenches with slip-resistance grip exceed ASME B107.100 standards.
