Key Specifications & Geometry
- Compact Footprint: Because a 3/8" fastener requires precise handling rather than high-leverage heavy torque, the tool features a compact overall length of 145 mm (5.7 inches).
- Aeronautical Standards: Engineered to meet SAE AS954G and ASME B107.100 aviation standards. It features narrow head profiles and a slim handle web to allow seamless access inside densely packed electrical or mechanical compartments.
- 12-Point Box-End Ring: Utilizes the patented OGV (Open Groove Profile) ring head. This design drives torque distribution through the flat sides of the 3/8" nut rather than putting pressure on the corners, preventing stripping.
- Dual 15° Offsets: The open-end jaw and the 12-point ring-end are both angled at a 15° offset relative to the handle shank to optimize clearance for your knuckles.
- Mass & Styling: Forged with premium steel alloy, weighs a light 45 grams, and is finished in a smooth, non-glare satin chrome
