Description
Stinger BKPRO Prodriver Skewdriver Original Patented 105 Degree Bevel Gear Offset Bit Driver with 100 In-Lb Torque and 1 Inch Head Profile
The BKPRO Prodriver Skewdriver from Stinger is the original patented 105-degree bevel gear offset bit driver, purpose-built for driving fasteners in confined spaces and hard-to-reach locations. A one-inch head profile provides access to areas where conventional screwdrivers and power drills cannot reach, with a 1:1 drive ratio, hardened steel internal gears, heavy-duty die-cast housing, and a 1/4-inch ANSI hex magnetic bitholder accepting all industry-standard bits. Rated to 100 in-lb torque and 600 RPM. Bits are not included.
Product overview
The 105-degree bevel gear mechanism transmits drive through a right-angle offset with a slight forward angle, allowing the Skewdriver to reach fasteners deep in dash cavities, behind speaker grilles, and in any location where a straight driver cannot fit. The 1:1 drive ratio means one full turn of the handle delivers one full turn of the bit through the hardened steel gears, maintaining reliable torque transfer without mechanical disadvantage.
The 12-position adjustable stabilizer wing provides grip and leverage in awkward positions, and the removable 6-flute storage handle allows the Skewdriver to be used directly with low-speed power drivers at up to 600 RPM. Bits are not included. The BKPRST2 kit version includes the same Skewdriver with a 40-piece bit set, magnetic extensions, stabilizer, and storage case, and is the better value option if bits are also required.
Features and benefits
Original patented 105-degree bevel gear offset drive: The patented bevel gear mechanism drives fasteners at a 105-degree angle relative to the handle, providing access to confined spaces and hard-to-reach fastener locations where straight tools cannot fit.
One-inch head profile: The compact one-inch head profile allows the Skewdriver to access tight spaces including deep dash cavities, behind speaker grilles, and other locations inaccessible to standard screwdrivers and power drills.
1:1 drive ratio with hardened steel gears: One full turn of the handle equals one full turn of the bit, transmitted through hardened steel internal gears for reliable and consistent torque transfer.
Heavy-duty die-cast housing: The die-cast metal housing provides long-term durability for repeated use in professional installation environments.
12-position adjustable stabilizer wing: The 12-position stabilizer wing can be positioned to provide grip and leverage in awkward or confined working positions.
1/4-inch ANSI hex magnetic bitholder: The standard magnetic bitholder accepts all industry-standard 1/4-inch hex shank bits including Phillips, Torx, Allen, flat blade, and Robertson. Bits are not included.
Removable 6-flute storage handle and power driver compatible: The removable 6-flute handle allows the Skewdriver to be chucked directly into a compatible low-speed power driver. Rated to 600 RPM and 100 in-lb torque.

Frequently asked questions
What is the difference between the BKPRO and the BKPRST2?
The BKPRO is the standalone Skewdriver offset driver only with no bits included. The BKPRST2 is the full kit version adding a 40-piece hardened steel bit set, two magnetic extensions, a stabilizer, and a storage case. If bits are also required, the BKPRST2 is the better value option.
What does the 105-degree offset mean?
The 105-degree bevel gear mechanism means the bit exits at a 105-degree angle relative to the handle, essentially a right-angle drive with a slight forward angle. This allows the Skewdriver to reach fasteners in locations where a straight tool cannot fit, such as deep in dash cavities or behind speaker grilles.
Can the BKPRO be used with a power drill?
Yes, at low speed only. The removable 6-flute handle allows the Skewdriver to be chucked directly into a compatible low-speed power driver. The BKPRO is rated to 600 RPM and 100 in-lb torque. Do not exceed these ratings as doing so may damage the bevel gears.
What bits does the BKPRO accept?
The BKPRO accepts any standard 1/4-inch ANSI hex shank bit. Bits are not included. The BKPRST2 kit version includes a compatible 40-piece bit set if bits are required.
Is the BKPRO the same Skewdriver as the one included in the BKPRST2 kit?
Yes. The BKPRO is the standalone version of the same Skewdriver offset driver included in the BKPRST2 kit. The BKPRST2 adds the bit set, magnetic extensions, stabilizer, and storage case.
