Crowfoot spanner No. 540 21 mm across flats 3/8 inch drive length 44.5 mm - Stahlwille 02200021

Where brake lines, hydraulic fittings or union nuts sit in tight spaces, a closed socket will not fit. The crowfoot spanner No. 540 engages the nut from the side with its open jaw (21 mm across flats) and is driven through its 3/8 inch square drive by a ratchet, extension or torque wrench. With a height of only 6.3 mm (dimension a) it also works in narrow gaps.

Benefits

• Open jaw with 21 mm across flats for nuts on lines and pipes
• 3/8 inch female square drive for ratchets, extensions and square-drive torque wrenches
• Compact dimensions: length 44.5 mm, width 41 mm, dimension a 6.3 mm
• Low weight of 59 g
• Chrome Alloy Steel, chrome-plated

Applications

Car and commercial vehicle workshops, hydraulics and pneumatics, plant and machine building: wherever fittings on lines can only be reached from the side. Combined with a torque wrench, such connections can be tightened in a controlled way. If the crowfoot is not mounted at a right angle to the lever, the effective lever length changes and the set value has to be corrected accordingly.
