What size are bike frame bolts?
The most common sizes of allen screws for bikes are 4, 5, and 6mm. There’s even a common bike tool that will fit in all three. In my experience, most racks use 5mm screws, but some do use 4 or 6mm screws.
What size wrench do I need for bike?
You’ll be able to use a 6mm or 8mm hex wrench for most pedals, but a decent pedal wrench is needed for other systems (eg. Speedplay). While a 15mm spanner may work, often you need the narrow profile of a proper pedal wrench. Leverage is key, don’t go for the very cheapest options as they’re often lacking in length.
How do you measure a bike nut?
Place the end of a measuring tape on one of the flat sides of the nut’s outer perimeter. Stretch the tape measure across the nut’s diameter to the flat-side directly across from the one your pulling from. If the nut is metric, count the number of lines on the tape measure to find the measurement.

Can I use a regular wrench instead of a pedal wrench?
Determine Your Pedal’s Size Since you don’t have a pedal wrench, typically, your standard 15 mm open-end wrench will do the trick just as easily. Once you’ve located the flat wrench spindle next to the bike pedal, it’s time to get to work.
Do I need a special wrench to change bike pedals?

How do you read a nut size?

- Read the third number, generally the one following the “x.”
How do I know what size axle I need for my bike?
Measure the straight length of your axle shaft. Do not include the axle head or tapered spacer, if there is one. Axle length is not the same as hub length. A bike with a 12×142 hub standard will have a significantly longer axle since it will have to go through the frame on both sides of the 142mm wide hub.
