There’s nothing more frustrating than needing a specific hex key and not having it. Hex keys are small and underappreciated parts that are often essential to the work of service professionals, contractors and do-it-yourself enthusiasts. Find the hex keys that you need at FMW Fasteners.
Our selection of hex keys includes a wide range of alloy options that meet different specifications. Order in the exact amount you need rather than settling for some arbitrary amount, and return what you don’t use at any time — as long as the hex keys remain in like-new condition.
What Are Hex Keys/Allen Keys?
Hex keys are also known as Allen keys or Allen wrenches, and they're small, handheld tools used to drive bolts and screws with hexagonal sockets. Each hex key is made from one rod that is shaped like a hexagon with blunt ends that will fit into the screw's socket. A hex key is bent into an "L" shape with different sized arms, and you hold and twist the long arm. This creates a large amount of torque at the tip of the short arm while reversing the tool allows you to utilize the long arm to reach fasteners in hard-to-reach places.
Every hex key has a hexagonal-shaped tip but comes in a variety of sizes. You can measure the size of hex keys across-flats (AF), which is the distance between the two opposite ends of the flat side. When you need a hex key to drive a bolt or a screw, it's critical to choose the right size key, as one that's too big could damage your fastener or tool.
What Are Hex Keys Used for?
Hex keys or Allen wrenches offer multiple benefits for driving bolts and screws. If you need to choose between Allen keys or a standard Phillip's head, you should keep in mind the following pros:
- Hex keys have six pressure points while a Phillip's head only has four
- Hex keys are designed to create less risk of stripping the bolt or screw
- Hex keys reduce fatigue, so you can work more efficiently
With the six pressure points on an Allen wrench, you'll be able to grip your screw or bolt easier and have a simpler time driving the screw in or out. This makes a big difference if you're taking apart or assembling a larger product such as a piece of furniture, machine or equipment. The six points on a hex key will reduce fatigue and make you more efficient.
