Slipping / Camming out

 
 Screwdriver bit and screw 

When driving certain types of screws, the screwdriver bit can slip out of the screw head, when a lot of torque (turning force) is applied.

 

This is also known as ‘camming-out’ and can result in the screwdriver bit damaging the screw head or the work surface.

 

Torx screws and screwdriver bits are designed to prevent cam out.

 
     
   

Stripping a screw head

 
 Stripped screw 

A stripped screw head is the term used to describe a screw that has been damaged by a screwdriver bit.

 

Stripped screws are the result of a number of things:

 

  • General wear and tear

  • Using the wrong size or type of bit for the screw

  • The screwdriver slipping out of the screw’s drive and damaging its surface.

 
     
  Wonkee Donkee says; A stripped screw is usually a ruined screw. If a screw’s drive has become misshapen, the screwdriver bit may not be able to remove it.
