Abstract

Nut drivers are common tools used in industry for the installation of screws and nuts. One of the difficulties in using a nut driver is holding the nut (or screw) being installed in the nut driver during installation. There are a number of solutions to this program currently available in commercial nut drivers which use a magnetic or non-magnetic mechanical means. Illustrated in Figure 1 is a simple, low cost, non-magnetic alternative to those methods. The device is constructed and operates as follows. A standard nut driver is cut through to its hexagonal opening so that when an "O" ring of proper diameter is installed, a slight interference will exit (see Fig. 2). This interference retains the nut until it is installed. When the "O" ring wears so that the retention force is inadequate, it is replaced with a new one.

Nut Driver "O" Ring Nut Retention System

      Nut drivers are common tools used in industry for the
installation of screws and nuts.  One of the difficulties in using a
nut driver is holding the nut (or screw) being installed in the nut
driver during installation.  There are a number of solutions to this
program currently available in commercial nut drivers which use a
magnetic or non-magnetic mechanical means.
      Illustrated in Figure 1 is a simple, low cost, non-magnetic
alternative to those methods.  The device is constructed and operates
as follows.  A standard nut driver is cut through to its hexagonal
opening so that when an "O" ring of proper diameter is installed, a
slight interference will exit (see Fig. 2).  This interference
retains the nut until it is installed.  When the "O" ring wears so
that the retention force is inadequate, it is replaced with a new
one.
     The disclosed system is particularly useful in applications
involving nuts made of non-magnetic material, applications where the
presence of magnetic fields is unacceptable, or where a simple
retro-fit to add a retention system to existing hardware is desired.
Low initial cost and maintenance is obtained by using commercially
available nut drivers and "O" rings.
