Difficulty: EasyScrewdrivers

A technician is removing an automotive interior panel secured with screws that feature a six-point, star-shaped recess. Which type of screwdriver is designed specifically for this fastener?

  1. A
    Phillips screwdriver
  2. Torx screwdriverAnswer
  3. C
    Robertson screwdriver
  4. D
    Slotted screwdriver

Answer

The Torx screwdriver is designed specifically for six-point, star-shaped fastener recesses.
A Torx screwdriver is specifically manufactured with a six-pointed star-shaped tip to fit matching star fasteners, which are widely used in automotive trim and components to handle higher torque without slipping.

Step-by-Step Solution

1
Identify the geometric profile described in the problem.
The fastener head features a six-point, star-shaped recess.
Fastener recesses correspond directly to matching screwdriver drive tip profiles.
2
Match the star-shaped geometry to standard screwdriver drive types.
Torx drivers utilize a 6-lobe/6-point star pattern; Phillips is a cross, Robertson is a square, and slotted is a flat blade.
Using the exact matching drive type ensures proper torque transfer and avoids stripping or cam-out.
