Basic tool requirements

The basic hand tools described below
can be used to accomplish most of the
simple maintenance and repair tasks.
Screwdrivers. The common flat-blade
type and the Phillips type will handle
almost all screws used on BMWs. Two
or three different sizes of each type will
be required, since a screwdriver of the
wrong size will damage the screw
head.
A complete set of screwdrivers should
also include Torx® type screwdrivers.
Wrenches. Wrenches come in different
styles, including open-end, 12-point
box-end, 6-point box-end and flare nut.
The basic open-end wrench is the most
widely used, but grips on only two
sides. The box-end wrench has better
grip on all six sides of a nut or bolt.
A 12-point box-end can loosen a nut or
bolt where there is less room for
movement, while a 6-point box-end
provides better grip. For hex fasteners
on fluid lines, like brake lines and fuel
lines, a flare-nut wrench offers the
advantages of a box-end wrench with a
slot that allows it to fit over the line.
The combination wrench is the most
universal. It has one open-end and one
box-end. 10 mm and 13 mm wrenches
are the most common sizes needed. A
more complete set of wrenches would
include 6 mm through 19 mm sizes.
