Know your measuring units

Do you need sizing in imperial or metric units? Trying to fit a ⅛ bit into a 3mm hex screw might almost work, but knowing that you need a 3mm screwdriver bit may be what saves you from stripping your screw. Luckily Kingsdun offers hex bit sets in both to help you cover all of your bases. We have sets that include both SAE & MM (like our #1000 Mity Master, #5575 Master Set, or #7331) or sets that focus individually on SAE (such as our #5589 or #8900) or MM (#1916 or #2309).

Have size options

Of course having a variety of size options will help make any job easier. Kingsdun offers a wide range of sizes from .050” and 1.3mm for SAE Allen Hex to 5/18” and 8mm for Metric Allen Hex (includes 4.5mm and 5.5mm half sizes). 

Have tool options

Kingsdun tools are all interchangeable with our handle and extension. This means, you can put any bit directly into the handle OR attach the extension to the handle and put the bit in the extension for a further reach. Having a versatile hex bit set can save you valuable time. Our famous midget ratchet with an extension helps you achieve the classic “L” Allen Key shape while using your hex bits. 

Get tools that will last, but are easy to replace if they don’t. 

Kingsdun tools will last you a lifetime- but we understand that accidents happen. Kingsdun makes replacing bits easy by keeping all of our bits and tools open stock at a low price. Our philosophy is that we would rather you break your bit than mar your screw. Other companies may require you to purchase another complete hex bit set when you only need to replace a single piece. Kingsdun keeps our bits open stock so that replacements are convenient and easy to get.

Make sure they are durable

Made from USA tool steel, heat treated, and with a black oxide finish, Kingsdun tools are meant to withstand heavy use. While our tools are nice to look at, we ultimately value how well they work and how hard they will work for you. Our tools are known to last a lifetime and pass from generation to generation. Hex bit sets can be easy to come by, but Kingsdun has the both the history and reputation of quality on our side.

Ease of use means getting the job done right

Having tools that are easy to use and work well together can make all the difference. No one wants to be scrambling to find tools that work together. Kingsdun sets come in neat, easy to store cases where everything is in one place, making grabbing just the right tool simple to do. We offer a great mixture of sets, some small enough to fit in your pocket and durable injection mold cases to add to your tool collection.

What is a Hex Key Wrench?

Since these tools are known by quite a few names, many ask 'is a hex key the same as an Allen wrench?' The short answer is yes. A hex key wrench is a simple hexagon-shaped tool that is used to drive bolts and screws with hexagonal-shaped socket heads into walls, furniture, metal, etc. These tools are usually L-shaped and come in various sizes from 1/16-inch to 3/8-inch. Precision hex wrenches for use in electronics can be as small as 0.028 inches. Some of these have long handles for better access to hard-to-reach areas, and others have T-handles (or P-handles) for better grip and easier usage. SAE and metric sizing, and sometimes both, are available, depending on what suits you better, 

What is the Best Allen Wrench Set?

Simply put, the best Allen wrench set to buy would be one with many different sizes, and preferably a case to keep them all neatly organized so you can find them easily when you need them. Opting for a set made from a durable material like chrome vanadium steel with an oxide finish will ensure they last you a long time. For more specialized concerns, consider whether hex keys with handles or a folding set would suit you better.
