Insert Installation Methods
Yardley self-tapping inserts are ideally suited for high volume
assembly operations because of their easy, quick installation. Inserting
a self-tapping insert is as simple as driving a self-tapping screw
or tapping a thread. A drilled hole of correct size must be provided,
driver tool is applied to insert, driver and insert are positioned
over the hole, insert is driven (turned) home and the driver is
backed off, leaving the insert installed. The insert cuts its own
threads as it is driven into the base material. The methods listed
below can be used to install Yardley TRI-SERT and FIBERSERT inserts.
Using Self-Tapping Insert Drivers
Because it is driven by its internal threads, a different driver
is required for each insert size. Thread cutting can be accomplished
by either end because there is a lead on both ends of the insert.
Alignment is important and the insert driver should be used with
a hand tapper or a tapping head attachment on a drill press without
a lead screw. For applications in recessed areas or close to walls
or ribs, a Yardley Extension Driver may be used to facilitate installation.
Inserts should be installed flush or below material surface. Thus,
when one assembles a bracket and screw to the insert, the load is
not transmitted directly through the insert but to the surface of
the boss or the material in which the insert is installed. This
is especially important where vibration is encountered.
TO ORDER YARDLEY SELF-TAPPING INSERT DRIVERS
Use the driver
prefix followed by the insert thread size:
HR - for standard
HRX - for standard extension driver
HR2 - for low volume driver
HRX-25020 = 1/4-20 standard extension driver
