What to Compare Before Buying
- Thread size and pitch: This set uses M5 and 0.8 mm pitch, so the matching thread is the main fit check.
- Length: The stated bolt length is 18 mm, so compare that with the space and fastening need on the stem.
- Tool size: The bolt uses a 4 mm hexagonal wrench width, so confirm your wrench matches.
- Pack quantity: This is a 6 pack, which matters if you need replacements or a full set.
- Included washers: Washers are included, so check whether that matches the fixing you want to replace.
Compatibility, Size and Fit
These bolts are specified as M5 with a 0.8 mm pitch. That is the main compatibility check, along with the 18 mm bolt length and 4 mm wrench width. Match those details with the fixing point on the bike stem before choosing an offer.
The washers are included as part of the pack, which is useful if you want a like-for-like replacement for a stem fixing that uses washers.
What Else You May Need
A 4 mm wrench is needed for fitting, as the wrench is not included.
Care, Cleaning and Storage
The bolts are described as titanium alloy and are noted for corrosion resistance. Regular inspection is still sensible: check for wear, deformation or stripping and replace the bolts promptly if needed.
Before You Decide
Confirm the M5 thread, 0.8 mm pitch and 18 mm length against your bike stem before choosing an offer. Check that you have a 4 mm wrench available, and make sure the included washers suit the fixing you plan to replace.
