Crowfoot spanner heavy-duty 540a HD size 13/16" with 3/8 inch square drive, length 51 mm - Stahlwille 02501042

The heavy-duty crowfoot spanner 540a HD with size 13/16 inch tightens imperial nuts and bolts where a socket cannot be fitted over the joint, for example on pipe fittings. It is designed for particularly high loads, such as stainless steel bolted joints. Its 3/8 inch internal square drive fits ratchets or torque wrenches. With a length of 51 mm and a weight of 113 g it stays compact.

Benefits

• For particularly high loads, e.g. stainless steel bolted joints
• Full use of the open-ended spanner in combination with standard ratchets or torque wrenches with fixed square
• 3/8 inch internal square drive for drive tools with a matching external square
• Compact design: length L 51 mm, width B 46.4 mm, dimension a 11 mm
• Chrome-plated finish

Applications

Manual screwdriving on imperial fasteners with size 13/16" in confined spaces, combined with 3/8 inch ratchets, extensions and torque wrenches with square drive. On a torque wrench the crowfoot extends the lever arm, which must be taken into account when setting the torque.
