The Diablo 2 in. Torx Security Drive Bit Variety Pack (model DTHV2-S7) is built for pros and serious DIYers. This is a Torx security screwdriving bit set designed for professional fastening in drills and impact drivers.

Torx security screws have a pin in the center of the recess to keep standard bits out. That makes them common on public restrooms, commercial fixtures, appliances, electronics and vehicles. This bit has the matching center hole, so it drives and removes those tamper-resistant screws without damaging the pin.

The Grip Point Tip is precision-machined to fit the fastener recess tightly, which reduces slipping and stripping. Behind it, the Increased Torsion Zone absorbs the hammering torque of an impact driver so the tip does not crack. Laser markings make the size easy to identify at a glance.

Included: (1) 2 in. Torx Security T10 Drive Bit, (1) 2 in. Torx Security T15 Drive Bit, (1) 2 in. Torx Security T20 Drive Bit, (1) 2 in. Torx Security T25 Drive Bit, (1) 2 in. Torx Security T27 Drive Bit, (1) 2 in. Torx Security T30 Drive Bit, (1) 2 in. Torx Security T40 Drive Bit.

This is a solid choice for electricians, HVAC and mechanical techs, facilities maintenance crews, installers and anyone doing assembly or service work with a drill or impact driver.

Diablo's next-generation bits give you a better-fitting tip and impact-rated shaft at a price that makes them easy to keep stocked.

• Who it's for: Pros and serious DIYers who use an impact driver for everyday fastening.
• Why it stands out: Grip Point Tip for fit and an Increased Torsion Zone for impact durability.
• Worth knowing: These are not the diamond-coated Demon line. If you are stripping screws in high-torque work all day, step up to Demon.

• Will this work on a regular Torx screw? Yes. A Torx security bit drives standard Torx screws of the same size too. A standard Torx bit will not fit a security screw.
