Frequently Asked Questions

Q. What is the major difference between oval and round machine screws?

A. oval machine screws feature a head that combines the characteristics of flat and round heads. The top of the head is slightly rounded, providing decorative finish at the top. While round head screws have a fully rounded head which prevents them from sitting flush with the material they are driven into, causing their heads to protrude like little bumps.
