OPEN RING insert tool 733/10 size 21 mm tool holder 9 x 12 mm - Stahlwille 58231021

Fittings on pipes, brake lines or hydraulic lines cannot be reached with a closed ring spanner because the line is in the way. The OPEN RING insert tool 733/10 has an open ring head that slips sideways over the line and turns a torque wrench with a 9 x 12 mm tool holder into a tool for union nuts with 21 mm across flats. The bi-hex still grips the nut on its flanks, so the tightening torque is applied in a controlled way. At 38.5 mm wide and 15 mm high the head stays slim, and it weighs 88 g.

Benefits

• Open ring head: slips sideways over lines where a closed ring does not fit
• Bi-hex with AS-Drive profile: torque is applied to the flanks, protecting the corners of the nut
• For torque wrenches with a 9 x 12 mm interchangeable insert system
• Special chromium over nickel plating, durable and chip-proof finish
• Drop-forged, hardened and cooled in an oil bath, extremely strong and exceptionally durable

Applications

Assembly, maintenance and servicing on pipes, brake, fuel and hydraulic lines, and wherever 21 mm union nuts are tightened or checked with a torque wrench for 9 x 12 mm insert tools.
