FAQs

Does this tool work on metric bolts?

No, this tool is specifically sized for imperial fasteners (5/16 and 11/32 inch). Using it on metric bolts can result in slippage and damage to the hardware.

Is the ratchet reversible?

This model is a straight flat spanner; to reverse the direction of the turn, simply flip the spanner over.

What is the primary advantage of the 72-tooth gear?

The 72-tooth gear creates a 5-degree working arc, which is ideal for working in very restricted spaces where you have limited room to swing the handle.

How long is the spanner?

The total length of the tool is 128 mm.

Can I use this for high-torque applications?

While the spanner is built for durability, it is designed for precision fastening. Avoid using extensions or 'cheater bars' which can damage the ratcheting mechanism.

Troubleshooting

Ratchet mechanism feels sticky or gritty

Clean out any debris with compressed air and apply a drop of high-quality light machine oil to the gear teeth.

Spanner slips on the fastener

Verify that the fastener size matches the imperial specification exactly and ensure the spanner is seated fully onto the head of the bolt.

Pros and Cons

Pros

  • Ultra-low profile design ideal for narrow gaps
  • 72-tooth ratchet allows for minimal movement per turn
  • Satin chrome finish resists rust and wear
  • Compact 128mm length provides excellent portability
  • Professional build quality for long-term reliability

Cons

  • Lacks offset, which may make flush-mounted bolts harder to reach
  • Limited to two specific imperial sizes
  • Flat handle design provides less leverage than long-handled variants

Setup, Compatibility & Care

This spanner is ready for immediate use out of the box as no calibration or assembly is required. It is compatible with standard 5/16 inch and 11/32 inch hexagonal and bi-hexagonal fasteners. To maintain the tool's performance:

  1. Wipe clean with a lint-free cloth after exposure to oils or contaminants.
  2. Apply a light machine oil to the ratcheting mechanism periodically to ensure smooth engagement.
  3. Store in a dry, organized toolbox tray to prevent surface scratches.
  4. Avoid using the spanner as a hammer or prying tool to preserve the integrity of the ratcheting mechanism.
