About this item

  • 4 IN 1 DESIGN: This 4-piece thin wrench set features a 4-in-1 design, offering 16 SAE sizes across 4 combinations: 11/32"-9/32" & 1/4"-5/16"; 9/16"-7/16" & 3/8"-1/2"; 13/16"-3/4" & 5/8"-11/16"; 1"-1-1/16" & 7/8"-15/16". Each open end wrench combines four clearly marked sizes, saving space and reducing the need for multiple tools while ensuring versatility for various tasks.
  • CR-MO Steel: Thin, but strong. Made from premium CR-MO (Chromoly) steel with a frosted finish. Chrome plating ensures excellent rust resistance, while heat treatment maximizes strength and extends the thin wrenches set’s lifespan.
  • Super-Thin: Engineered with precise dimensions for a tight grip on nuts and bolts, reducing the risk of rounding or slippage. The double open-end design ensures secure and efficient use in tight or awkward spaces where traditional wrenches cannot reach.
  • Portable Rolling Pouch: The super thin wrench set comes with a high-quality rolling pouch for easy organization. Its compact, lightweight design makes it ideal for carrying to job sites or storing in your workshop, ensuring both convenience and portability.
  • Wide Application: The TIWINTUL 4-in-1 super-thin open end wrench set features a slim design and versatile sizing, perfect for tight spaces where traditional wrenches fail. Covering 16 SAE sizes (1/4 to 1-1/16 inches), it’s ideal for automotive repairs (working in tight spaces like engine bays and brake systems), plumbing (adjusting pipe fittings and valves in confined areas), bicycle and motorcycle maintenance (handlebars and pedals), home repairs (furniture assembly and appliance fixes), and machinery maintenance (SAE bolts on small machines).

This wrench set is fantastic for tight spaces! The ultra-slim design makes it easy to reach nuts that regular wrenches can’t. The quality feels solid, and having multiple sizes in one set is super convenient. A great addition to any toolbox!

These wrenches are thinner than my other wrenches.I like the fact that there are different sizes on each end, and that there is a smaller size within each wrench head.These 4 items replace one big bag of wrenches through which I would always have to dig and find the size I needed at any given time. At least now I can just carry these 4 with me and find out which one is needed for a task.Each unit in this set is also more lightweight than any of my similar wrenches. That makes it easier to carry and use, plus I've found that I am much less likely to drop one of these when using them.I'm not a fan of the carry holder in which they are stored. It takes up a huge amount of space, and I don't have so much space that I can just set this carry cover separately from the rest of my tools.

These are very unique wrenches that are different from any of ever seen. Instead of one wrench being used for two different size nuts or bolts, each one of these in this set can be used for four different sizes.

The idea of thin wrenches that are multiple sizes is a great idea. Question is how thin is too thin? I have used these a couple of times in "staged" environments and yes they do work but durability and not stripping the wrench would be something I would always have to consider.They come with a case but it is clear that these were not designed for the case and they slide out easily.

These 4-in-1 Super-Thin Open End Wrench 5-Piece wrench set by TIWINTUL is rather innovative.The design of this wrench set is ingenues and of excellent craftsmanship and quality.The ultra slim design is a must have and will fill the void and limitations of your standard mechanics tool set. This set by TIWINTUL comes in a well made portable tool roll to protect aid in organization while ensuring longevity. They seem to be of great durability; they light weight especially for their sizes which is much longer than most. They feel good in the hand and the added length makes them easy to use and less strenuous. Overall I'm very happy with the design, quality of craftsmanship and value and would highly recommend for these are of commercial grade quality and super versatile.

I got these for working with routers where it’s sometimes tough to fit a regular wrench. The thin cross section is pretty great for sneaking in tight spaces and they’re working welI for me.I haven’t had call to use the twin-fitted portion and I’m a bit leery to do so. Seems to me that this is a recipe for stripping nuts/bolts, or bashing knuckles. Not having the nut or bolt seated nice and deep seems like a good way to slip off. To be fair, I haven’t had this happen, but I’m not sure this is a good feature.Still, glad to have.

I selected this product for review mostly out of curiosity. It’s kind of hard to tell from the photos, but these really are some very thin wrenches. They are attempting to do everything, all at once, with almost one tool. Inevitably this will go wrong, but that’s not really the point of these tools. If anything, the carrying case may be a little bit too thick for what they are, and I will probably end up losing the case and just dropping these inside my travel tool set. I’m not really expecting much out of a slim profile wrench, but we’ll see what they can do in the future. I think at the $28 price point, they are a perfect set of portable tools for someone who is prioritizing weight over being fully practical.There is an argument to be made that you could go with quick adjustment pliers for roughly the same price as the set of four tools. There are Amazon alternative knock off to the knipex plyer wrench that would probably serve the same function, but I do believe the low profile of these wrenches offers a unique tool, assuming the bullet you’re trying to maneuver is exactly the size of one of the wrench heads.For the lowered weight, I would probably spend the extra money to get a nicer set of adjustable pliers, but some people really like wrenches

Like many DIY enthusiasts and professional mechanics, I've often found myself in situations where a standard-width wrench just won't fit. It can be incredibly frustrating to be in the middle of a project without the right tools. That's why I ordered this ultra-thin open-end wrench set in metric sizes, which has proven to be a great alternative for these tricky situations.One standout feature of these wrenches is their 4-in-1 design. This set includes five wrenches that cover 20 different metric sizes, accommodating a wide range of tasks.The wrench set comes with a durable custom canvas roll-up holder, and both the manufacturing quality and finish are impressive. I compared these wrenches with other brands of the same size, and I found that they are within specifications.These wrenches are made from Chromoly steel, which is a type of low-alloy steel named after its two main alloying elements: chromium and molybdenum. Chromoly steel is often used when higher strength is needed compared to mild carbon steel. It boasts an exceptional strength-to-weight ratio, making it significantly lighter than regular steel while providing equal or greater strength. I believe Chromoly steel was chosen for these wrenches to handle high torque, especially given how thin they are.My initial experience with these wrenches has been very positive. The price point is reasonable, making it a great idea to have some on hand for those occasions when a regular wrench won't fit. These wrenches are essential for both DIYers and professional mechanics. While they may not be something you need every day, when you do require a thin wrench, these could be exactly what you need.
