Stock Drive Products pioneered the concept of combining the exceptional qualities of
selected plastic materials with different metals to create products which incorporate both.
SUPER-PLAST® designs have the following advantages:
1. Inexpensive replacement of metal components, particularly for low torque
applications.
The above products are available from stock in standard configurations as presented in
the catalog pages. They can also be manufactured to special requirements, with partial
modification of existing tools. These "specials" can consist of:
a) Bores molded to accommodate square, "D" shape or hexagonal shafts.
