Just as the title
suggests, these are thumb style screws used for mounting
rack equipment. They function in much the same way
as any rack mount screw with several significant
These screws can be installed and removed completely by
hand allowing you to install and remove rack gear
without the need for any tools (see photos right).
2. When speed installation is required you
can use a power driver and 9mm hex socket (not included
with this auction) to install these screws in just about
3 seconds (see photos - right). We don't know of
any one piece rack screw / fastener that can be
installed and removed as quickly.

Clip / cage nuts needed when
using punched hole (unthreaded) racks are not included in this auction.
rack equipment will these work with?"
all rack mount equipment can be mounted with these
screws. This includes music, video, broadcast,
telecom, DJ, data (server, router, switch, hub.
Unlike standard rack screws
which are formed in one operation these screws are precision
machined from single piece
carbon steel. Five operations are needed to make
each screw and for reference purposes each screw weighs
4 times what a standard phillips truss head rack screw weighs. Indeed, these are very "beefy"
screws and are far more expensive to manufacturer than a
standard rack screw.
a 9mm Hex Head?
I chose this size as it allows a socket or wrench to fit
easily between 2 over & under thumb screws (see
photos). Anything larger would prohibit
installation with a socket or wrench. Anything
smaller would not adequately cover the equipment panel

thread size is right for you? The following are the
most common and we offer them all:
American screw size. Commonly used in all rack
mount applications including music, video, broadcast, data and more. 90%
of the screws and fasteners we sell are 10-32. The "10" refers
to the drill size for a tapped (threaded) hole. This thread has 32 threads per inch.
12-24 An American screw size still common for rack
mounting equipment particularly in the US telecommunications industry.
It has 24 threads per inch. Again, the first number
refers to the drill size required for a tapped (threaded) hole.
It is larger in diameter than a 10-32 screw and smaller than an M6 screw.
8% of the screws we sell here in the US are 12-24.
M6 Metric thread size of 6 millimeters. Typical thread
size for European rack applications. Also used in
Compaq racks and Euro racks sold here in the US. Larger than both 10-32
