Product Overview
The Urrea 31213 Metric Open-End Wrench is a precision-engineered hand tool designed for professional technicians and mechanics requiring reliable access in confined spaces. This double-ended wrench features 12mm and 13mm openings with a slim profile to navigate narrow clearances effectively. Forged from a high-quality molybdenum-vanadium steel alloy and treated with controlled thermal processing, this wrench delivers high tensile strength and durability for rigorous industrial applications.
To enhance performance on damaged fasteners, the wrench incorporates Urrea's patented UGS system. This design distributes torque force across three distinct points rather than solely on the corners, significantly reducing stress and preventing further rounding of stripped edges. Additionally, the wrench head features a 15° inclination angle, allowing the recovery angle to be reduced to 30° when working with 6-point bolts, making it highly effective for obstructed nuts and pipe joints.

Frequently Asked Questions
Q: What is the advantage of the UGS system on the Urrea 31213 wrench?
A: The UGS system changes how torque is applied to the fastener. By distributing the mechanical force across three contact points instead of just the corners, it minimizes stress on the edges and allows the tool to effectively grip and turn nuts or bolts that have already been stripped or rounded.
Q: How does the 15-degree inclination angle improve usability?
A: The 15-degree head angle allows you to flip the wrench over after each turn. On 6-point bolts, this reduces the required recovery angle to just 30 degrees, making it significantly easier to loosen or tighten fasteners in tight, restricted spaces where a full swing is impossible.
