Q 1. What size fasteners does the Draper 3936 spanner fit?

A. The Draper Expert HI-TORQ® 3936 double ring ratchet half moon spanner is sized 15 x 17 mm, fitting fasteners of those two metric sizes at either end.

Q 2. What makes HI-TORQ® ring ends different from standard ring spanners?

A. The 12-point Draper Expert HI-TORQ® ring ends grip the flats of a fastener rather than its corners. This spreads the load across the flat faces, transmitting more torque to the nut or bolt while reducing the risk of rounding or damaging fastener corners.

Q 3. How small a swing arc does the ratchet mechanism require?

A. The 100-tooth ratchet delivers 3.6° of movement per stroke, allowing the spanner to be used effectively in locations where there is very limited space for swing.

Q 4. What material and finish does this spanner use?

A. The spanner is manufactured from hardened and tempered chrome vanadium steel and carries a mirror chrome plate finish, which provides corrosion protection.

Q 5. Is this spanner available as part of a set?

A. Yes. The Draper Expert HI-TORQ® double ring ratchet half moon spanner is available individually or as part of a five-piece set supplied in a wallet/roll.
