FAQs

What does 'Bi-Hex (12pt)' mean?

Bi-Hex means the socket has 12 points of contact instead of the standard 6 points found on a typical socket. This provides a more secure grip on the fastener, especially beneficial for rounded or worn bolts.

What is the main advantage of the open jaw design?

The open jaw allows the wrench to be slid onto a fitting even when the line (pipe or cable) is still attached and runs close to the fitting, which is impossible with a standard closed socket.

Can I use this with a breaker bar?

While it's compatible with any 3/8" drive tool, it's recommended to use it with a standard 3/8" drive ratchet or torque wrench. Using a heavy breaker bar could exceed the torque rating of the fastener or the wrench itself.

What is the 'pivot point' mentioned for the extension bar length?

The 43mm extension length is measured from the point where the drive connects to the crows foot head to the center of the fastener engaging jaws.

Is this wrench suitable for general bolt tightening?

No, this is a specialized tool designed for specific tasks like removing brake, fuel, and hydraulic lines. For general tightening, standard sockets are more appropriate.

What materials is the wrench made from?

The wrench is manufactured from durable Chrome Vanadium steel, with a matt finish on the extension bar and a manganese phosphate coating on the wrench head for corrosion resistance.

What other sizes are available in this range?

This is part of a range of 3/8" drive flexible crows foot wrenches available from 10mm to 22mm, with part numbers ranging from 8425 to 8437.

Troubleshooting

Wrench slips on fastener

Ensure the correct size fastener is being used (16mm). Check that the bi-hex profile is fully engaged and not obstructed. Verify the fastener head is not excessively worn or rounded.

Difficulty reaching fastener

Utilize the 43mm extension bar for added reach. Consider using a longer or more flexible 3/8" drive extension bar if clearance is extremely limited.

Corrosion or rust spots

Clean the affected area with a light abrasive pad or wire brush. Apply a thin layer of light oil or rust inhibitor to protect the surface. Ensure proper storage in a dry location.

Wrench does not fit around pipes/cables

Confirm that the obstruction is not too large for the open jaw design. This wrench is designed for line fittings where the line runs *adjacent* to the fitting, not necessarily around very bulky components.

Pros and Cons

Pros

  • Specifically designed for difficult-to-access line fittings.
  • Open jaw design overcomes obstructions like pipes and cables.
  • Durable construction from chrome vanadium steel.
  • Corrosion-resistant finishes enhance longevity.
  • Flexible extension aids in reaching awkward angles.

Cons

  • Specialized tool, not for general-purpose use.
  • Limited to 3/8" drive systems.
  • Open jaw may offer less torque than a fully enclosed socket.
  • 16mm size is specific to certain fittings.

Setup, Compatibility & Care

Setup:

  1. Select the appropriate 3/8" drive ratchet or extension bar.
  2. Attach the 16mm flexible crows foot wrench securely to the drive.
  3. Position the open jaw over the target fastener, ensuring it is fully seated.

Compatibility:

  • Drive Size: Compatible with all standard 3/8" drive ratchets, torque wrenches, and extensions.
  • Fastener Type: Primarily designed for 16mm hex or bi-hex fasteners, specifically those found on brake, fuel, and hydraulic lines.
  • Environment: Suitable for automotive and workshop environments.

Care:

  • Clean the wrench after each use with a clean cloth to remove grease and debris.
  • Store in a dry environment to prevent corrosion.
  • Avoid using excessive force that could exceed the tool's or fastener's limits.
  • Periodically check for wear on the jaw edges and drive interface.
