Metric Hexagon Setscrews - DIN 933
Hexagon Setscrews
Hexagon Setscrews have a hexagonal shaped head so that they can be used with a standard spanner and are ideal for use in heavy duty fastening applications.
These are also known as fully threaded hexagon bolts and as the name would suggest, these are threaded all the way up to the head and are therefore perfect for installing into pre-threaded holes.
