Frequently Asked Questions

A pan head self-drilling screw has a rounded base and a flat head that sits on top of the material it fastens. With its large diameter and high edges, the drive slot is deep, which allows for increased torque while minimizing the risk of damage to the screw.

Both are commonly used for metal applications. Pan head machine screws can also be differentiated from flat head screws, which have flat tops, as well. However, flat head screws are tapered on the underside of the head so they can lie flush with the material they’re driven into.

Type A screws are often referred to as sheet metal screws, though they are not a self-drilling tek screw. The phillips drive pan head offers an attractive, smooth, rounded, relatively low-profile head design with a phillips drive

The Difference Between Pan Head Screws And Button Head Screws. Button head screws have chamfered sides which curve all the way down to the bottom of the screw head. They have a slightly domed top but they do not have straight sides like pan head screws

Length is measured from the point at which the head sits flat with the surface, to the tip of the threads. Hex, pan, truss, button, socket cap, and round head screws are measured from right under the head to the end of the threads. Flat head screws are measured from the top of the head to the tip of the threads.
