Product overviewOverview
Bits fail either by tip wear or by torsional fracture. S2 steel quenched and tempered to roughly HRC 60 wears slowly but has limited toughness; tip geometry decides contact area, and a tip that is slightly off-size concentrates load on the lobe tips and multiplies wear rate.
Material: S2 Alloy Steel. It is installed by 1/4-inch chuck on electric or pneumatic driver.
Key featuresFeatures
- S2 alloy steel quenched and tempered to about HRC 60.
- Tip ground to the standard recess form for six-lobe face contact.
- 1/4-inch hex shank fits electric and pneumatic drivers.
- Full T6–T40 range to match the recess sizes in use.
Typical applicationsApplications
- Consumer electronics assembly
- Robotic driving stations
- Precision instrument service
Selection notesSelection
Match bit to recess type (standard or enhanced); mixing them accelerates wear on both parts.
Frequently asked questionsFAQ
How do I specify the TORX Screwdriver Bit?
Match bit to recess type (standard or enhanced); mixing them accelerates wear on both parts. Material: S2 Alloy Steel. It is installed by 1/4-inch chuck on electric or pneumatic driver.
What matters during installation of the TORX Screwdriver Bit?
Match the bit size to the recess designation — the next size up will cam out and damage both parts S2 alloy steel quenched and tempered to about HRC 60.

Manufacturing and inspection
Tip dimensions are checked on a profile projector against the recess standard.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
