Frequently Asked Questions (FAQs)

1. What size are BMX bolts?

Replacement stem bolts that fit most current BMX stems. Sold in packs of 6, featuring a 6mm allen key hex and standard M8*P1. 25mm thread. Made by Mission BMX!...Tech Specs.

2. What size screws do bikes use?

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.

3. What screws are used in bikes?

You should only use screws with a tensile strength/yield strength of 8.8 or better (9.8, 10.9 or 12.9) for motorbikes. Low-value screws, which are readily obtainable from a DIY store for example, are of an insufficient quality (too soft). Steel nuts are identified by their tensile strength.

4. What wrench size do BMX tire screws use?

The socket wrench, extension and 17mm socket are something you're going to need in that tool box of yours. Although female axles are becoming more common, the trusty 14mm male axle with the 17mm nuts are still the most common.
