Spring
action
The diameter of the bushing is slightly larger than the hole.
The spring action of the bushing allows it to be installed into
a drilled or cored hole and assume the diameter of the hole.
It is self retained once in the hole.
Staggered
Seam
The staggered seam prevents interlocking, making these bushings
suitable for automatic feeding and eliminating the need to
separate
them during manual assembly.
Lead-in
chamfers
The beveled chamfer around the entire periphery of the bushing
is designed to facilitate ease of insertion and to avoid skiving
of the bushing during installation.
Controlled
inside diameter
The inside diameter of the dowel bushings is designed to provide
clearance for a bolt through the bushing for the purpose of
fastening the aligned components together. This isolates the
bolt from the shear loading and increases the joint integrity.
It also eliminates the cost of a separate hole.
