Screw Head Types & Drives

Head shape controls how a screw seats and looks; the drive controls how much torque you can apply. Here is how to choose the right combination for your assembly.

Common head types

HeadProfile & typical use
PanRounded top, flat bearing surface. The all-round general-purpose head.
Countersunk (CSK)Flat, conical — sits flush with the surface. Joinery, panels, flush finishes.
Raised CSKCountersunk with a slight dome — flush but decorative.
TrussWide, low dome — spreads load over thin or soft material.
CheeseCylindrical with flat top — machine assemblies needing a deep slot.
Hex / Hex FlangeSix-sided for spanner driving; flange adds a built-in washer face.
BugleTrumpet-shaped underside — self-countersinks into drywall and timber without tearing.
Button / SocketLow dome with internal hex — high-torque, clean look.

Common drive styles

  • Slotted: simplest, but cams out easily — low torque only.
  • Philips (PH): self-centring, designed to cam out to limit torque.
  • Pozidriv (PZ): like Philips but with extra ribs for better grip and less cam-out.
  • Torx (star): six-point star — highest torque transfer, minimal cam-out, ideal for power tools.
  • Square (Robertson): strong grip, good for one-handed driving.
  • Hex / Allen: internal hex socket — high torque in a compact head.

Picking a combination

For high-volume powered assembly, a Torx or Pozi drive reduces cam-out and bit wear. For flush finishes use a CSK or Bugle head; for thin or soft materials a Truss or Pan head spreads the load. We manufacture 9+ head styles across all product lines.
