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
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.

Swivel Head Wrenches
By Bondhus |
 |
These wrenches are particularly useful for
driving Socket Cap screws, Button heads and Grub screws where nearby
obstructions make access awkward. By altering the angle of the long
handle, screws can be rotated without having to repeatedly remove
the driver from the socket.
Both ends are hexagonal so the wrench can also be used as a long
reach allen key. |

Please note that the
sizes below are the A/F dimension, the across flats dimension of the
socket they fit. This is not the metric screw size they are used to
tighten. As an example, an M2 metric cap screw requires a 1.5mm A/F
driver, not a 2mm driver.

where you will find a
table of driver sizes for various screw types and sizes. |
