What is a socket set screw?
A Set Screw is a headless screw fully threaded from end to end. Traditionally classified within the Socket family of
products, Set Screws are comprised of 3 main parts: the drive, the thread and the point.
Can you use a set screw on a round shaft?
When the round shaft is soft and the set screw is harder, the outer diameter surface of the round shaft will be scratched. If the outer diameter surface of the round shaft is scratched, it will become difficult to move when readjusting the round shaft.
What size are set screws?
Common sizes range from #0 to #12 and 1/4" to 1 1/2"—small sizes are expressed as whole numbers and large sizes as fractional
inches—and lengths span from 1/16" to 6" for socket set screws. For square head set screws, available sizes are from #8 to #12 and
1/4" to 1 1/2", while lengths range from 7/32" to 12".
