Double Open End Spanners Cold Stamped (DIN 3110)

The Bi-hexagon Ring Spanner with a Carbon Steel Matt Finish is a wrench designed for gripping the flats (hexagonal sides) of nuts and bolts. Unlike traditional open-ended spanners, it fully encloses the fastener, providing a stronger grip and reducing the risk of rounding off corners. The “bi-hexagonal” design refers to the 12-sided shape that fits on both the nut and the bolt head for better torque application.

Made from Carbon Steel, this spanner offers a balance of affordability and durability. While not quite as strong as some alloy steels, it’s a good choice for general purpose tasks. The Matt Finish provides a subtle, non-reflective appearance and may offer slightly better grip compared to a polished finish.
