Buyer Questions
Frequently asked questions
What's the difference between a machine screw and a bolt?
Functionally there is significant overlap, especially at smaller sizes. Generally, a machine screw is smaller (typically below M8), has a uniform thread along the full length, and is intended to be turned into a tapped hole or held with a nut and tightened from the screwdriver/wrench head. A bolt is generally larger and intended to be held by a nut tightened from the nut side. The terminology is loose in practice.
