M3X0.5 Torx Pan Head

M3X0.5 Torx Pan Head Screw - A4 Stainless ISO 14583

Torx Drive pan head screws have a wide diameter head profile with rounded, chamfered / curved sides and a recessed six-lobe drive.

Machine thread screws can be used in a tapped hole or with a locking / non-locking nut. Length is measured from underneath the head.

Also known as metric hexalobular socket pan head cap screw, raised cheese head torx screw, machine pan head torx drive screw.

A six lobe torx wrench is used to install these screws, allowing access into spaces where a traditional external hex drive bolt would not fit. Torx drive screws provide higher torque transfer because the driving forces are transferred to each surface of the six lobes (wobble-free), instead of the four edges of the four edges on a phillips drive.
