Draper Expert HI-TORQ Ratchet Combination Spanner Set - Metric Flexible Head 12 Piece

HI-TORQ refers to Draper's specific design for the ring end of the spanner. It grips the flats of the fastener rather than the corners, providing a stronger grip, transmitting more torque, and reducing the risk of damaging the fastener's corners.

Wipe them clean with a dry cloth after use. For tougher grime, use a damp cloth with mild degreaser and dry thoroughly. Store them on the provided rack in a dry location. Periodically inspect for wear and lubricate the ratchet lightly if needed.

No, this is a metric set and is designed for metric-sized nuts and bolts. It is not compatible with imperial (SAE) fasteners.

A 100-tooth ratchet requires a smaller swing arc (3.6 degrees in this case) to engage the next tooth. This is extremely beneficial in tight spaces where you may only have a limited area to move the spanner handle.

The flexible head offers excellent maneuverability but, like most flexible head tools, may have slightly more flex than a rigid head under extreme torque. For maximum torque applications where space is not a constraint, a rigid spanner might be preferred. However, for its intended use in tight spaces, it performs effectively.

The spanners are manufactured from hardened and tempered chrome vanadium steel, which provides excellent strength and durability.

This set includes 12 common metric sizes. While it covers a wide range of typical tasks, it's always advisable to check the specific sizes included against your project requirements.

Ensure the spanner is clean and free of debris. Try applying a small amount of light tool oil to the mechanism. If the issue persists, the internal mechanism may be damaged, and the spanner might need replacement.

Verify you are using the correct size spanner for the fastener. Ensure the HI-TORQ ring end is fully seated on the flats of the bolt or nut. Check for excessive wear on both the spanner and the fastener. For extremely worn fasteners, consider using a specialized extraction tool.

A small amount of play in the flexible head is normal for maneuverability. However, if the head feels excessively loose or unstable, it may indicate wear or damage. Inspect the pivot point for debris or damage. Persistent looseness may require replacement.

For light surface rust, try cleaning with a brass brush or fine-grade steel wool, followed by a light application of oil. Ensure the spanner is dried thoroughly and stored in a dry place to prevent further corrosion.
