Simple and economical
Set Screw Couplings are a cost effective style of rigid couplings.
They function by gouging the set screw into the surface of a shaft. They are a low-cost alternative when frequent adjustment is not a consideration.
The addition of a second set of screws greatly increases the load capacity.
Round bore sizes are available both with and without keyways
Stocked in steel, additional sizes and materials are available upon request.
