Description
Stinger BKPRO Prodriver Skewdriver with Patented 105° Bevel Gear Offset Drive
The original patented offset screwdriver a 105-degree bevel gear mechanism drives fasteners in tight, hard-to-reach spaces where standard drivers can't go, with 100 in-lb torque capacity and heavy-duty die-cast construction.
Product Overview
The Stinger BKPRO Prodriver Skewdriver 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 compact one-inch head profile allows it to access areas where conventional screwdrivers and power drills simply can't fit.
The 1:1 drive ratio means one full turn of the handle equals one full turn of the bit transmitted through hardened steel gears for reliable torque transfer. The heavy-duty die-cast housing is built for long-term durability. A 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.
The standard 1/4-inch ANSI hex magnetic bitholder accepts all industry-standard bits, and the unit is rated for 100 in-lb torque and up to 600 RPM.

Frequently Asked Questions
What is the difference between the BKPRO and the BKPRST2?
The BKPRO is the standalone Skewdriver offset driver only — no bits are 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 you need bits, 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 access screws in locations where a straight tool cannot reach, such as deep in dash cavities or behind speaker grilles.
Can this be used with a power drill?
Yes, at low speed. The removable 6-flute handle allows the Skewdriver to be chucked directly into a low-speed power driver. It is rated to 600 RPM and 100 in-lb torque — do not exceed these ratings to avoid damage to the bevel gears.
What bits does this tool 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 required.
Is this the same Skewdriver as 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.
