Match each screw drive type on the left to its defining recess geometry and mechanical characteristic on the right.

  • Robertson driveSquare-shaped recess that holds driver bits firmly and reduces slippage
  • Torx driveSix-pointed star-shaped recess designed for high torque transmission
  • Hex (Allen) driveSix-sided internal socket commonly driven with an L-shaped wrench
  • Phillips driveCruciform cross-shaped slot with tapered flutes designed to cam out under excessive torque

Cevap

Robertson matches the square recess; Torx matches the six-pointed star recess; Hex (Allen) matches the six-sided internal socket; Phillips matches the cruciform cross recess with tapered flutes.
Each screw drive is matched to its unique geometrical profile: Robertson is square, Torx is a six-pointed star, Hex is a six-sided internal socket, and Phillips is a cross-shaped recess with intentional cam-out taper.

Adım Adım Çözüm

1
Identify the Robertson drive geometry
Matched with the square-shaped recess
Robertson fasteners are defined by their square socket profile.
2
Identify the Torx drive geometry
Matched with the six-pointed star-shaped recess
Torx fasteners utilize a star pattern with six lobes to handle high torque without stripping.
3
Identify the Hex (Allen) drive geometry
Matched with the six-sided internal socket driven by an L-shaped wrench
Hex drive fasteners feature an internal hexagon designed for Allen keys.
4
Identify the Phillips drive geometry
Matched with the cross-shaped cruciform recess with tapered flutes
Phillips heads use a cross shape specifically engineered with angled corners that cam out under heavy torque.
