6-Lobe Tx CSK Machine Screw

6-Lobe TX Countersunk Head Machine are similar to DIN 7985 and are also known as Torx® screws.

They host a 6-Lobular Recess and are driven using a mating wrench or insert bit ranging from TX5 to TX55. This makes the screws more efficient that slotted screw products due to hosting more resistance to cam out and ability to be used with power drivers – which allows higher torque levels to be achieved.

The drive had long been used within the automotive industry, before being superseded by the 5-Lobe TX+ Drive.

Available as standard in sizes ranging from M1.6 to M8, with other diameters and lengths available upon request.

These screws are also available in UNC, UNF, Self Drilling, Thread Forming and Self Tapping forms.

Please contact us with your requirements to further your enquiry.
