AVS Tools

Combination Spanner is a double-ended tool with one end being like an open-end spanner & the other end being like a ring spanner. The ends are generally designed to fit the same size bolt. The open end is set at 15 degree & the ring end is finely machined for perfect geometry.

It comes with similar features as in the case of combination spanner the only difference being its elliptical shape that offers comfortable grip and easy movements. The spanner is manufactured by drop forging high carbon steel. The shaft and ends are thoroughly polished and chrome plated for durability and abrasion resistance.

The Double Open Ended Spanners are the most common types and have a double end. The head has its jaws offset by anything between 15 degrees to 90 degrees from the run of the shaft and the shaft may have a slight curve. The design is such that the spanner can be turned over to engage different flats of a nut when working in confined spaces. Double Open Ended spanner are available with following specifications:

The Cross Wheel Spanner is made out of specially selected steel which is deep forged to impart higher strength. The hexagonal box spanners at the ends have exceptional geometrical finish to tightly engage various sizes bolts and nuts. The cross intersection has high tensile fusion and a neat finish. The box and cross are chrome enameled for durability and abrasion protection. Four Way Cross Wheel Spanner are available with following specifications:

The ring spanner normally has an enclosed head, and come with 6 or 12 flats. A 12 flat spanner engages upon the corners of the nut and can engage both hexagon and square bolts. A six flat spanner is normally shaped to fit against all 6 sides of hexagon nuts, this ensures a tight fit more than that of Open ended spanner and allows considerable force to be applied. Ring Spanner are available with following specifications:
