Fixed Ratchet Combination Wrench (13mm)

That makes it one of the two or three sizes genuinely worth having as a ratchet spanner rather than a plain one, because 13mm fasteners come in numbers and are frequently in places where a spanner handle has very little room to swing.

The 72-tooth mechanism is the specification that decides whether it works in those places. Tooth count sets the swing arc — how far the handle must travel before the pawl catches the next tooth and the fastener turns — and 72 teeth gives five degrees where a coarse 24-tooth ratchet needs fifteen. Behind an alternator or under a bellhousing, five degrees is often all there is.

There is a trade with fine teeth that is worth understanding rather than discovering. Smaller teeth carry less load each, so a 72-tooth ratchet is not a breaker bar. The right sequence is to crack a seized fastener with a plain ring spanner or a socket, wind it out with the ratchet, and tighten with a socket and torque wrench where a figure matters. That habit is what makes a good ratchet spanner last.

The open jaw at the other end slides onto a fastener from the side, for speed and for the ones a ring cannot drop over.

Forged from chrome vanadium steel, hardened and tempered, with matt chrome plating for corrosion protection.

The buyers are vehicle, commercial vehicle and bus mechanics, agricultural and plant fitters, engineering and fabrication workshops, industrial maintenance, and hardware dealers supplying the motor trade.

Two habits. Push the ring fully down onto the fastener before pulling. And check the ratchet direction first, because a ratchet set the wrong way slips and feels exactly like a broken one. Message us on WhatsApp for a price.
