Stripped bits mid-repair are every mechanic's nightmare. Whether you're a professional auto technician, a PC builder, or a hands-on DIYer, you need Torx bits that hold their edge under real torque. This S2 Steel Torx Bit Set is built for exactly that — delivering consistent, reliable performance across T6 to T40 star sizes.
Each bit is machined from German-sourced S2 alloy steel and heat-treated to HRC60± hardness, giving you a tool that resists deformation, wear, and cam-out even under high-torque pneumatic and electric screwdrivers. Available in 50mm (12-piece with box), 75mm (11-piece with box), 100mm (11-piece with box), and 150mm (8-piece) configurations to match your reach requirements.
From tightening automotive engine bolts and assembling flat-pack furniture to repairing gaming consoles and laptops, this Torx power bit set covers the full range of star-drive fastener applications — with a magnetic tip that keeps screws locked in place for one-handed driving.
Compatible with all standard 1/4" (6.35mm) hex shank power tools — pneumatic screwdrivers, cordless drills, electric screwdrivers, and impact drivers from DeWalt, Milwaukee, Bosch, Makita, and more.
Tackle engine bolts, interior panels, and suspension components with the 100mm or 150mm sets — long enough to reach recessed fasteners without an extension.
The 50mm set covers T6–T10 sizes used in laptops, gaming consoles, and smartphones — with a magnetic tip that prevents screws from disappearing into tight chassis.
The 75mm set is the go-to for flat-pack furniture, appliance installation, and general home improvement tasks where a mid-length bit gives the best control.
Keep a full set on hand for machinery maintenance and equipment servicing — S2 steel hardness means these bits survive repeated high-torque cycles without deforming.

The 50mm set typically includes T5–T40 (12 pieces). The 75mm and 100mm sets generally cover T8–T40 (11 pieces each). The 150mm set includes T8–T40 (8 pieces). Exact sizes may vary slightly — refer to the variant listing for the specific size breakdown.
Yes. The standard 1/4" hex shank fits impact drivers, cordless drills, electric screwdrivers, and pneumatic tools. However, for sustained high-impact use, we recommend the 50mm or 75mm sets for best torque transfer and bit longevity.
S2 alloy steel is harder and more impact-resistant than standard CRV steel. After heat treatment, S2 bits typically reach HRC60±, compared to HRC50–55 for most CRV bits. This means S2 bits are less likely to deform or strip under high torque, making them better suited for power tool use.
The 50mm, 75mm, and 100mm sets each include a durable compartmentalized plastic storage case. The 150mm set does not include a case due to the length of the bits.
For most automotive applications, the 100mm or 150mm sets are recommended. Longer bits allow you to reach recessed fasteners in engine bays, door panels, and suspension components without needing an extension bar. For general interior trim work, the 75mm set is generally sufficient.
Yes. The 50mm set includes the smaller Torx sizes (T5–T10) commonly used in laptops, smartphones, and gaming controllers. The magnetic tip helps retrieve and position tiny screws in tight chassis without dropping them.
Yes, as long as your manual screwdriver handle accepts a 1/4" hex bit. Many bit-holder handles and ratchet screwdrivers use this standard shank size, making these bits versatile for both power and hand tool use.
