Our range of small self tapping screws are intended for
small fixing applications into hard woods, soft woods, plywoods,
composite
boards, soft plastics, sheet metals etc. As the name suggests, self tappers
create their own mating threads
as they are applied, to give a vibration
resistant assembly.
Ideal for flying model applications such as canopies,
cowls, fan housings, and inspection hatches etc.
Unlike wood screws, self tappers are threaded all the way up to the underside of
the head making it possible to
use them for clamping very thin materials together
*Please note that
the length specified is from underneath the head to the end of the threaded
shank,
with the exception of the countersunk screws where the length specified
is the overall length (includes the head)
 |
Using the correct driver is essential for success with
miniature self tappers so as not to 'round off' the cross or slot head. We stock
good quality screw drivers with the correct tips for our very small sizes as
these can be difficult to obtain from usual tool suppliers.
If you need a driver, note the driver tip ref and select the correct
driver from the tools listed at the bottom of this page - please scroll down,

As with all miniature hex drive screws, care
should be taken not to over drive. In hard woods, plastics and metals,
always
pre-drill an appropriate sized pilot hole (the harder the material the larger
the pilot hole) and try on a scrap piece
first whenever possible. If using an allen key, always use the short arm to drive the screw and not the long arm.
Use
extreme care if using a socket drive screwdriver with a large grip as the forces
at the key to head interface will be many
times higher than the effort you apply
and may lead to stripping of the socket if the material is hard and the pilot
hole too small.
***We
do not recommend the No 0 size for use in hard materials such as plywoods, hard
plastics and metals due to the danger
of drive socket stripping if the pilot
hole is not optimum diameter.
Unfortunately it is impossible for us to provide a
range of pilot hole sizes due to the large range of possible materials.
