- Made of high-speed steel that provides better performance and greater service life when using it on machinery ,- High-speed steel provides, compared to carbon steel, higher resistance to friction and torsion
This unique design is mainly used in repairs and maintenance of refrigeration systems, where often times the nuts or couplings are made from soft materials, thus the importance of having a perfect fit, to avoid damaging the parts
They help tighten or loosen pipe joints made mainly with soft metals, like bronze, copper and aluminium
They have an ergonomic geometry that improves grip and fastening since their openings are precision-cut
