This T20 x 75mm Torx Star Bit with a 10mm shank is a screwdriver bit intended for driving T20 (TX) Torx fasteners in both hand-held and powered bit drivers. Its primary use is to engage Torx screws where a positive, six-point contact is needed to reduce cam‑out and deliver reliable torque transfer in assembly, maintenance and repair tasks.

The bit is manufactured from S2 tool steel and has been heat-treated to a high torsional strength (typically in the 58–62 HRC range) to resist tip deformation and wear. The tip conforms to industry Torx dimensional profiles and is produced to common DIN/ISO drive tolerances to ensure accurate mating with Torx-headed screws. The 10mm shank is suitable for use with 10mm bit holders or socket adaptors; thread type is not applicable for this product as it is a drive tool, and the head type is a male Torx (star) tip sized T20. A black phosphate finish provides basic corrosion resistance and reduces surface glare during use.

Typical applications include automotive trim and interior work, furniture and kitchen assembly, appliance repair, bicycle and motorcycle maintenance, and general workshop or manufacturing assembly where Torx fasteners are specified. Industries that commonly use this bit include motor vehicle servicing, joinery and cabinetry, white goods repair, and light engineering production lines.

Key benefits of this T20 bit are its material strength and precise tip geometry, which combine to deliver durable service life and consistent engagement with Torx screws. The S2 construction gives good resistance to torsional stress, the controlled finish helps resist rust in normal workshop environments, and the standardised tip dimensions ensure compatibility with Torx fasteners from major manufacturers. The 75mm length gives extra reach into recessed or awkward locations compared with shorter bits.
