Similar to DIN 84, but with a larger head diameter and a slightly different head profile. Manufactured to ISO 1580 or DIN 85. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Also known as star, 6 lobe, and hexalobular internal. Torx screws are commonly found on cars, motorcycles, bicycle brake systems, hard disk drives, computer systems and consumer electronics and are becoming increasingly popular. Once, they were typically used in applications requiring tamper resistance; as drivers became more common, specific tamper-resistant variants were developed. The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head. Conforms with DIN 7985.
