Q 1. What is the arc of movement on the 3917 ratchet mechanism?

A. The 100-tooth ratchet on the Draper Expert HI-TORQ® 11mm Flexible Head Ratchet Combination Spanner enables 3.6° of movement per stroke, allowing effective use where the swing arc is very limited.

Q 2. How does the HI-TORQ® ring end differ from a standard spanner?

A. The 12-point Draper Expert HI-TORQ® ring end grips the flats of the fastener rather than the corners. This spreads the load across the flats, transmitting more torque and reducing the risk of rounding or damaging the fastener corners.

Q 3. What material is the spanner made from and how is it protected against corrosion?

A. The spanner is manufactured from hardened and tempered chrome vanadium steel and finished with black electroplating, which provides corrosion protection.

Q 4. How much does the flexible head articulate?

A. The head flexes through 180°, and the open end is set at 15° to the shaft, giving the spanner considerable adaptability in restricted or awkward access situations.

Q 5. Is the 3917 available as part of a set?

A. Yes. The Draper Expert HI-TORQ® Flexible Head Ratchet Combination Spanners are available individually and in sets. Sets are supplied in a storage and carry rack.

Q 6. Can I ask questions about this product before ordering?

A. Yes — WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility, and we'll help you choose the right product.
