Hex Set Screw
Hex Set Screws conform to DIN 933 standard and are essentially a fully threaded hex bolt. They are commonly used to hold collars, pulleys or gears on shafts in ironmongery and joinery applications.
Metric Fine Hex Set Screw
Metric fine thread is a common thread.
A fine thread is known to be stronger than a coarse thread.
This is both in tension (because of the larger stress area) and shear (because of their larger minor diameter). Because of the smaller pitch, they allow finer adjustments in applications that need such a feature.
