Description

Low Head Torx Machine Screws, also known as 6-Lobe Machine Screws, are a specialized fastener designed to offer secure fastening while providing a reduced-profile head. These screws are widely used across industries where a combination of low-clearance requirements, strong torque transfer, and precision fastening are essential. From electronics and automotive assemblies to machinery and aerospace applications, Low Head Torx Machine Screws play a crucial role in delivering performance, reliability, and aesthetic appeal.

  • Low Head: Refers to the reduced height of the screw head compared to standard machine screws. This is particularly useful in tight-clearance applications where a protruding head could interfere with moving parts, aesthetics, or other design constraints. The head is typically cylindrical or slightly domed, with a lower profile than a standard pan or socket head.

  • Torx / 6-Lobe Drive: A type of drive system characterized by a six-pointed star-shaped pattern. Often referred to as a 6-lobe drive, this system allows for higher torque transmission, reduces cam-out, and extends tool life compared to traditional Phillips or slotted drives.

  • Machine Screw: A type of screw designed for precision fastening into pre-tapped holes or used with nuts. Machine screws have a uniform thread along the shank and are commonly used in metal-to-metal applications.

The notion of a drive with hexalobular sockets are a decisive step in developing drives better adapted to manual and automated assembly. This drive is becoming increasingly popular throughout the world.

Compared to drives like cross recesses and conventional hexagon sockets, this system is characterized by a lower risk of deterioration and a lower pressure force requirement. The typical «cam out» slipping of the tool has hence been eliminated and the force transmission improved.

The general dimensions are given in the product information of the respective catalogue group.

The Torx compatible drive is a reliable method of fixing screws. This drive can take more torque and does not slip.

The hexalobular socket screw drive, known as Torx or 6-Lobe or star drive, uses a star-shaped recess in the fastener with six rounded points.

It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. This system features a 15-degree drive angle which provides high torque transfer.

Radial forces are drastically reduced resulting in longer tool life.

It has vertical sidewalls which increases tool engagement CAMOUT is defined as the force upward on a screwdriver as the torsional force is increased to tighten the screw.

Torx Screws do not have camout problems as no camout forces are created to push the driver up and out of the fastener recess.

Due to this, the pressure required to keep the screwdriver in the socket reduces significantly and therefore reduces operator muscular stress and fatigue.

Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries. This is also the preferred drive for our range of JCSlim thin head screws.
