Frequently Asked Questions (FAQs)
1. 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.
2. 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.
3. What size are mountain bike stem bolts?
Application: Road or MTB bicycle stems. Size: M5x20mm in length. Fastener Type: 4mm Allen Tapered Head with Washer.
4. What size are bicycle bolts?
