adjustments need to be made without
significantly damaging the mating
material or part

Fastenal offers a diverse selection of set screws that are
durable and versatile for many applications. Set Screws are
used to hold and object in place by force through a tapped
hole. Cup point set screws are the most common style used.
Full Dog and Half Dog Points have an extended tip that fits into a hole
drilled in a shaft. Use these for permanent location of one part to
another. They often replace dowel pins. Length is measured in overall
length including the tip. Often used as adjusting screws, Flat Point,
Oval Point, Nylon Tip and Brass Tip screws cause little or no damage
to the contact surface. These screws are good for thin wall thickness
and soft plugs and designed for frequent resetting and relocating.
With flat points, greatest contact is provided on shafts with areas that
are ground flat.
