THREADED TEMPLATE BUSHINGS

STANDARD ID TOLERANCE:
From #55 to 1/2” +.0001/+.0015
(ID concentric with OD to within .002” TIR)
Retainer Ring
(TTR) INSTALLATION:
Drill hole in jig plate to nominal bushing OD (B diameter).
Countersink 90° to allow bushing to seat flush to .015” below surface
of plate (standard version only, not flanged version). Install and
tighten Retainer Ring to secure. To make Retainer Ring installation
easier, we offer a handy Socket-Type Installation Tool that fits 1/4”
square drives.

Threaded
Template Bushing
(TTB)

APPLICATIONS:
This economical bushing is designed for thin template jig plates from
3/64 to 3/8” thick. Bushings are held in place by a threaded Retainer
Ring (order separately). Left-hand thread is self tightening during
drilling to prevent the Retainer Ring from loosening. Flush contact
of the Retainer Ring against the jig plate ensures perpendicular drill
alignment. OD serrations prevent the bushing from rotating during
drilling. Choose standard countersunk type for flush mounting, or
flanged type for installation without countersinking the jig plate.
Threaded Template Bushings can be easily removed to replace or
reuse.
ORDERING EXAMPLES:
Available in 3/8”, 1/2”, 5/8”, 3/4”, and 1” OD sizes. Standard prices
apply to standard bushings only, with any standard inch or metric
ID size within the stated range.
