Please refer to the table below for the hexagon key
sizes for metric cap screws, countersunk socket screws and grub screws. Please
scroll down the page if you wish to purchase a correct size key, or a hexagon
ball-end driver (screw driver with ground ball/hexagon end allowing fast off
centre driving). Metric and inch sizes are listed
Below is also listed our telescopic
magnetic probes - ideal
for retrieving fasteners from hard to get places
It is essential to use the correct key size for driving cap
screws and grub screws etc. In particular, when tightening the smaller sizes of
grub screws, using an incorrect key (which may appear to be the correct size
before higher torques are applied ) can lead to rounding off of the hexagon
socket making removal or further tightening extremely difficult if not
impossible.
This information is supplied in good faith and is correct to
the best of our knowledge.
Inch size keys for our BA and UNC
socket cap screws range are also available below.
