FAQs

What material is the spanner made from?

The spanner is drop-forged from hardened and tempered chrome vanadium steel.

What is the primary benefit of the thin profile?

The thin profile allows the spanner to access nuts and bolts in confined or tight spaces where a standard spanner might not fit.

How should I clean the spanner?

Wipe the spanner clean with a cloth after each use, particularly if it has come into contact with oil or grease. Store it in a dry place.

Is this spanner suitable for impact wrenches?

No, this is a manual hand tool designed for use with hand pressure only. It is not intended for use with impact wrenches.

What does 'drop-forged' mean for this tool?

Drop-forging is a manufacturing process that shapes metal under extreme pressure, resulting in a stronger, more durable, and wear-resistant tool.

How do I know if this is the right size for my needs?

This spanner is specifically for 21mm nuts and bolts. Ensure the fastener you are working with measures 21mm across its flats.

Troubleshooting

Spanner slips on nut/bolt

Ensure you are using the correct size spanner (21mm) and that the nut/bolt head is not stripped or damaged. Apply firm, consistent pressure.

Difficulty accessing tight spaces

The thin profile is designed for tighter spaces, but if still obstructed, consider using a socket wrench with an extension or a different type of tool.

Visible wear or damage on jaws

Inspect the jaws for any signs of deformation. If significant wear is present, consider replacing the spanner to ensure proper grip and prevent damage to fasteners.

Pros and Cons

Pros

  • Durable construction from hardened and tempered chrome vanadium steel.
  • Thin profile enables use in confined spaces.
  • Mirror polished finish offers corrosion resistance.
  • Drop-forged for maximum strength and longevity.

Cons

  • Single size (21mm) limits its applicability to specific fastener sizes.
  • May require a set of spanners for comprehensive tasks.
  • Not designed for very high torque applications where impact wrenches might be needed.

Setup, Compatibility & Care

Setup: No setup is required. This is a hand tool ready for immediate use.

Compatibility: This spanner is compatible with any standard 21mm hexagonal or square nut and bolt head. It is designed for manual use and is not intended for use with power tools.

Care: To maintain the spanner's condition:

  1. Wipe clean after each use, especially after exposure to oil or grease.
  2. Store in a dry environment to prevent rust.
  3. Avoid exposing the tool to excessive force or incorrect applications, which could lead to damage or premature wear.
