Stahlwille Double Ended Ring Spanner 3/8 x 7/16 Inch

Stahlwille Series 20a Double Ended Ring Spanners. AF imperial, drop forged from high-grade special steels and chrome plated.

The spanners are optimally hardened in continuous furnaces with no scale build-up or skin decarburisation and gently quenched in oil. They are extremely strong yet lightweight due to Stahlwille’s ‘double-T profile’. The unique plating method prevents the problem of chrome flaking.

The ring end of the spanners are equipped with an Anti-Slip Drive profile to permit high transmission of forces to the flats of the nuts and bolts without damaging them.

Made in Germany.
