A threaded profile is the output end of a tool … or the head of the screw connection.

Why is this important?

• Choosing the correct profile
  • improves the fit within the screw head
  • reduces damage to the screw head
  • optimises force transmission
  • reduces slippage or damage

Here are some common screw profiles:

• Phillips-Recess profile (PH) ∙ Colour code: red
• Pozidriv profile (PZ) ∙ Colour code: black
• Tamper-resistant TORX® profile ∙ Colour code: pink
• TORX PLUS® profile
• Inside TORX® profile ∙ Colour code: green
• Traction profile
• Internal multi-tooth profile (XZN)
• Inside hexagon profile ∙ Colour code: light blue

By the way:

For some tools, the colour coding (HAZET colour code) makes it easier to find the correct screw profile
