Materials /Size / Type
- Double Ring Spanners are constructed using chrome vanadium (Cr-V) or carbon steel, the main material being chosen for its unparalleled strength as well as wear resistance. The steel is heat-treated through processes such as quenching and tempering for optimal hardness (generally 42–48 HRC) as well as toughness. spanners are chrome-plated or nickel-plated for resistance against corrosion as well as extended lifespan.
- Double Ring Spanner is manufactured with Size from 6x7mm up to 46x50mm.
- Types are Recessed panel, Flat Panel.
- Since it has 2 sizes within one Spanner, it is easier and time-saving for using multiple tasks. Its offset Ring ends can conveniently fit deep spaces where flat spanner cannot.
- Both of Ring ends are manufactured with 12 point Flank drive, enhancing the force applied on the bolt-nuts for closing or opening.
- Ergonomic handles minimize hand strain over time.
- Good quality of the spanners extends their lifespan and thus cut down costs such as replacements of spanners.
- Each spanner is strictly quality-checked through torque tests as well as dimensional inspections to meet/exceed standards (e.g., DIN 838).
