A-Lock fasteners are common to Beechcraft airplanes and latches on
many cowlings. The design consists of a simple stud, with a pin pressed
into the shank. The pin is installed after inserting the stud through
the panel hole and removed prior to removing the stud. Some installations
use a grommet in the fastener hole. Unlike other fasteners, the grommet
does not usually require replacement when installing new studs.
Base part numbers indicate stud diameter and head style. A-Lock studs
are made in several blank lengths indicated by the first dash number
in the charts. Each blank length can have up to 10 second dash numbers
or grip sizes. The second dash number indicates the maximum grip range
in .010² increments. Milspec primarily stocks sizes common to Beech
aircraft in stainless steel for repacement purposes. To remove an A-Lock
stud, simply clip or remove the pin enough to back the stud out of the
hole. New pins are pressed in using special pliers, or by modifying
standard vice grip pliers. Drill or cut one jaw of the vice grip to
allow proper relief for the pin. If new grommets are required, a flaring
tool is necessary (see below). |
