The BLUE PRINT brand Ring-/Open End Spanner is a versatile tool that will come in handy for many household and professional tasks. The most popular place to use open end spanners is the service station. Auto mechanics who repair cars and motorcycles often use these hand tools in their work.

The material of an open-end spanner

All spanners are made of high alloy steel and chrome vanadium. Each component brings its own advantage: Cr (chromium) provides resistance to oxidation, stress, corrosion and high temperatures, while V (Vanadium) contributes to the toughness of the steel and reduces graininess. Such a composition perfectly tolerates shock and prolonged loads, is durable. Among the manufacturing technologies that improve the quality of hand tools, it is worth noting cold stamping. This manufacturing method allows you to create tools of complex shapes. Cold stamping technology provides materials with the following advantages:

1. Manufactured parts may have a wall thickness measurable in hundredths of millimeters.
2. Thanks to the technology of cold stamping, it became possible to produce tools of complex shapes, which was impossible with other methods.
3. The formation of the part, without violating its integrity, allows you to increase the material utilization rate up to 95%.
