Super-Thin Open End Wrench Set - Reach Tight Fasteners Easily

In this review the Capri Tools Super-Thin Open End Wrench Set earns high marks for anyone who regularly works in cramped engine bays, on brake systems, or with hydraulic fittings. The single biggest reason to buy is the ultra low profile: with open ends as thin as 2.2 mm and a 15-degree tipped head, these wrenches let a technician access fasteners that standard wrenches simply cannot. Build quality and finish back up the design, making this a practical set for professional mechanics and serious DIYers who need tools that fit where others do not.

Key Features

• Ultra low profile: Open ends ranging from 2.2 to 5.6 mm thin allow access to fasteners in very tight clearance areas that thicker wrenches cannot reach.
• Angled head: The 15-degree tipped wrench head makes it possible to reposition and flip the wrench after each partial turn to maintain engagement in narrow spots.
• Forged Chrome Vanadium steel: A 10-step heat treatment process produces durable wrenches suited to professional use and repeated torqueing.
• Flawless chrome plating: Polished and chrome plated finish improves corrosion resistance and keeps the set looking clean after heavy shop use.
• Comprehensive size range: Fourteen open end wrenches cover 20 metric and 8 SAE sizes to handle common automotive and equipment fasteners.
• Organized storage: Included spill-resistant mechanics tray fits most tool chests and keeps each wrench accessible and secure.

Who It's For

This set is aimed at professional mechanics and experienced DIYers who frequently work on vehicles, brake calipers, hydraulic fittings, and assemblies with limited clearance. The thin profiles and tipped heads make tasks like caliper bleeds, ignition coil removal on compact engines, and plumbing of tight fittings much less frustrating.

Those who only occasionally need a single wrench size or who primarily work on applications with ample clearance may find a simpler, less specialized set more economical. Also, if a job requires offset or box-end access rather than open ends, a different wrench type would be a better choice.

Pros & Cons

Pros

• Exceptionally thin open ends that solve clearance problems other wrenches cannot.
• Strong forged Chrome Vanadium construction and thorough heat treatment for professional durability.
• Clean chrome finish that resists corrosion and stands up to shop use.
• Convenient spill-resistant tray keeps the set organized in a toolbox.

Cons

• Size selection draws mixed feedback, so individual users should confirm the included sizes match their most common fasteners.
• Open-end design may not substitute for box-end or combination wrenches where maximum contact and torque are required.

Frequently Asked Questions

Are these wrenches durable for daily shop use?
Yes. The set is forged from Chrome Vanadium steel and goes through a 10-step heat treatment, which gives them the strength expected for professional use.

Do the thin ends compromise strength?
The thin open ends are engineered for clearance tasks and retain strength through the forged construction, but for maximum torque or rounded fasteners a box-end tool may be preferable.

Will the tray fit a standard tool chest drawer?
Yes. The included spill-resistant tray measures 15-3/4 in x 7-1/2 in x 1-1/4 in and is designed to fit comfortably in most tool chests and cabinets.
