There is no definitive answer to this question as the size of Allen wrench needed for a 200 amp service will vary depending on the specific make and model of the electrical panel. However, it is generally recommended that a 3/8-inch or 1/2-inch Allen wrench be used for this purpose.
When it comes to Allen wrenches, size does matter – especially when you’re dealing with a 200 amp service. The standard size for this type of service is 1/2″, but there are also 3/8″ and 5/16″ options available. While the smaller sizes may be easier to work with, they won’t provide as much torque and could strip the bolts if you’re not careful.
So, if you’re planning on working on a 200 amp service, make sure you have the right size Allen wrench on hand before getting started.

What Size Allen Wrench for Electrical Panel?
If you’re in the United States, the size of Allen wrench you’ll need for your electrical panel will depend on the type of screws used to secure the cover. The most common type is a 1/4-inch hex head screw, but some panels use 3/8-inch or even 1/2-inch hex head screws. To be sure, it’s always best to remove one of the screws and take it with you to the hardware store to ensure you get the right size wrench.
In other parts of the world, metric sizes are more common. For those panels, you’ll want an Allen wrench that is 4 mm in diameter. Again, it’s best to remove one of the screws and take it with you to make sure you get an exact match.
What are Common Electrical Hex Sizes?
There are a few different types of hex sizes that are commonly used in electrical applications. The most common sizes are #6, #8, and #10. These sizes correspond to the diameter of the screw or bolt that they will be used with.
For example, a #6 hex size is typically used with a 1/4″ diameter screw or bolt. A #8 hex size is typically used with a 5/16″ diameter screw or bolt. And a #10 hex size is typically used with a 3/8″ diameter screw or bolt.
Hex head screws and bolts are also available in metric sizes.
The most common metric sizes are M3, M4, and M5. These sizes correspond to the thread pitch of the screw or bolt that they will be used with. For example, an M3 hex size is typically used with a 0.5mm pitch thread.
An M4 hex size is typically used with a 0.7mm pitch thread.
Are There Metric And Standard Allen Wrenches?
There are both metric and standard Allen wrenches. Metric wrenches are sized according to the metric system, while standard wrenches are sized according to the imperial system. Both types of wrenches can be used to loosen or tighten screws and bolts that have an Allen head.

3/8 Allen Wrench
An Allen wrench, also known as a hex key or hex driver, is a simple tool used to drive bolts and screws with hexagonal sockets in their heads. The Allen name is actually a registered trademark of the Apex Tool Group, but the term is commonly used to refer to any six-sided socket wrench, regardless of manufacturer.
Allen wrenches are available in a variety of sizes, measured across the flats of the hexagon (not the points).
The most common sizes are 1/16″, 3/32″, 1/8″, 5/32″, 3/16″, 7/32″, 1/4″ and 5/16″. Larger sizes up to 3/4″ are also available, but these are less common. In addition to standard and metric sizes, there are also miniature versions of Allen wrenches designed for use with small screws in delicate applications.
To use an Allen wrench, simply insert it into the hexagonal socket and turn clockwise or counterclockwise as needed. For best results, hold the wrench firmly in place while turning the bolt or screw with your other hand. If you’re having trouble getting enough torque on the bolt or screw, try using a longer Allen wrench or applying some lubricant to the threads.
Electric Meter Allen Key
An electric meter allen key is a small, handheld tool that is used to insert and remove the retaining screws on an electric meter. The allen key is inserted into the head of the retaining screw and turned in a clockwise or counterclockwise direction to loosen or tighten the screw. The allen key is held in place by friction and is not permanently attached to the meter.
3/8 Insulated Allen Wrench
Do you need an insulated allen wrench? Do you know what size to get? If not, don’t worry!
This blog post will tell you everything you need to know about 3/8 insulated allen wrenches.
An allen wrench is a type of hex key that is used to drive bolts and screws with a hexagonal socket. They are often used in tight spaces where a regular screwdriver cannot fit.
Allen wrenches come in many different sizes, but the most common size is 3/8.
3/8 allen wrenches are great for working with electrical circuits because they are designed to prevent electrostatic discharge (ESD). ESD can damage sensitive electronic components, so it’s important to use the right tools when working with them.
Insulated allen wrenches have a plastic or rubber coating that protects against ESD.
If you’re looking for an insulated allen wrench, be sure to get one that is rated for the voltage of your circuit. The higher the voltage, the thicker the insulation needs to be.
Most 3/8 allen wrenches are rated for up to 1000 volts, which is plenty for most household applications.
Now that you know everything there is to know about 3/8 insulated allen wrenches, go out and get one for your next project!
3/8 Allen Socket
An Allen socket, also known as a hex socket or internal hex drive, is a type of socket that has a six-sided head. This type of socket is often used for driving screws and bolts with an Allen wrench (hex key). The advantage of using an Allen socket over other types of sockets is that the head of the screw or bolt is less likely to slip out since it is surrounded by the sides of the socket.
Additionally, Allen sockets are less likely to strip the head of the screw or bolt since they evenly distribute force around the entire circumference of the head.
Conclusion
The size of the allen wrench you need for a 200 amp service is 1/2″. This is because the allen wrench is used to secure the lugs on the breaker, and the 1/2″ size will fit over the studs on the breaker.
