WHAT TO LOOK FOR
Direction of travel
A simple arrow indicating clockwise or anti-clockwise will prove surprisingly useful and prevent errors when working blind.
Double ratchet ends
An easy way of carrying more sizes without sacrificing space.
Open end ratchet
A clever way of accessing fixings where a closed end wouldn’t fit or might become stuck in situ.
The number of ratchet stops determines the angle required to rotate the ratchet to the next stop. The more stops, the less movement required, which is preferable. The 72-ratchet design gives 5° degrees of rotation per ratchet turn.
PIC 1: A flexible head that pivots on a removable threaded pin allows the joint to be tightened and cleaned, if necessary.
PIC 2: Spanner head sizes are similar, so check for access in confined spaces if you have specific tasks in mind.
PIC 3: Metric or Imperial? Most Metric sizes also cater for Imperial equivalents.
