Capri Tools Super-Thin Open End Wrench Set (Master Set) CP11850-14MST – Ultra-Low Profile

Capri Tools delivers a compact, professional-grade solution for fastener work in confined spaces with the Super-Thin Open End Wrench Set. This master collection blends a remarkably slim profile with durable materials to help you reach, engage, and turn fasteners where bulkier wrenches struggle. The set spans a wide range of metric and SAE sizes, making it a versatile addition to shops, service vans, or on-site toolkits.

Ultra-thin profile for tight spaces

Thickness varies from 2.2 mm in the narrow ranges to 5.6 mm in larger sizes, allowing secure access in slim gaps. The 15-degree angled head assists initial engagement in tight spots, and after each 15-degree turn you can flip the wrench to quickly re-engage the fastener, keeping work fluid and efficient.

Built to last under demanding use

Designed for professional workflows, these wrenches are forged from chrome vanadium steel and finished with a meticulous chrome plating. The steel undergoes a 10-step heat treatment to balance strength with long service life, while the durable plating offers enhanced resistance to corrosion in challenging environments.

• Ultra-low profile of 2.2–5.6 mm enables entry into cramped clearances
• 15-degree angled head improves access in narrow spaces
• Chrome vanadium steel with a 10-step heat treatment for reliability
• Flawless chrome plating for durability and corrosion resistance

What’s included and how it is organized

The Master Set consolidates 14 open-end wrenches in 20 metric sizes and 8 SAE sizes, covering from 6 mm up to 24 mm and 1/4 in to 3/4 in. The kit ships with a spill-resistant Mechanics Tray that keeps tools orderly between jobs and makes transport simpler.

Real-world use possibilities

From automotive underhood work to machinery maintenance and everyday repairs, the ultra-thin wrenches are designed to slip into restricted areas and provide consistent turning leverage. They can help reduce tool changes and enable steadier engagement in engine bays, panels, and compact housings.

While outcomes depend on the task, the design emphasizes accessibility, durability, and organized storage, offering a practical, no-pressure option for busy days in the shop or on-site service calls.
