Gas bottle wrench made from sheet steel, chrome-plated according to EN12540 standards. The wrenches are made from premium chromium-vanadium steel with higher density at high-pressure points and dimensions and construction that increase their power and durability.

With special safety cutting, the wrenches prevent damage to the corners and edges of screws and nuts by distributing force evenly over the surface away from the outer lines of the nut or screw head, instead of exerting force directly on the edges.

State-of-the-art design enables Unior wrenches to guarantee precise and effective power transfer for tightening heads and nuts.
