Product Description

Countersunk bolts are designed to fit flush to the surface of a countersunk hole. When screwed in the face of the head is the only visible part of the screw.  When empty these special holes look like a normal screw hole having a conical opening at the top.

There are two main reasons to use these bolts:

  • To create a smooth finish on an object without bolt heads sticking out.
  • To prevent the exposure of sharp edges.

Norwood Screw Machine Parts has a good reputation in manufacturing countersunk bolts.
