Frequently Asked Questions (FAQs)
1. 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.
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 size are bicycle bolts?
Fasteners: Usually one 3 or 4mm hex bolt on the underside of the bottom bracket shell; not all bikes have one.
