Capri Tools Super-Thin Open End Wrench Set, Metric, 6–19 mm, 7-Piece (11850-7MRK) | Premium Chrome Vanadium

Overview

Engineered for hard-to-reach fasteners, the Capri Tools Super-Thin Open End Wrench Set delivers accessible leverage and precise control in tight spaces. The wrenches combine a remarkably slim profile with robust construction, making them a versatile choice for professional workshops and serious DIY projects alike.

These wrenches balance form and function through thoughtful design features. They are crafted from premium Chrome Vanadium steel and undergo a complete 10-step heat treatment to ensure lasting performance. A flawless chrome finish protects against corrosion, helping maintain a clean working surface even after repeated use in challenging environments.

Engineering and Materials

The wrenches are designed to navigate confined areas with ease. The overall thinness ranges from 2.2 mm to 4.6 mm, with specific end thicknesses tailored to each size: 6 and 7 mm open ends at 2.2 mm; 8–11 mm at 2.6 mm; 12–15 mm at 3.6 mm; and 16–19 mm at 4.6 mm. The 15-degree angled head aids alignment, and after a 15-degree turn you can flip the wrench over to re-engage the fastener quickly, reducing fumbling in tight spots.
