Welcome to Tibike Titanium Bolts, all our bolts are manufactured to the highest standard, using grade 5 Aerospace Titanium alloy 6Al-4V. Every Titanium bolt purchased from Tibike comes with a LIFETIME WARRANTY.
Please note the socket of the bolt does not determine the bolt size! This is really important and a common mistake made. You measure the width of the bolts thread to come up with the "M6" value. For example a M6x20mm bolt has a 6mm thread width and the thread is 20mm long from the bottom of the head to the end of the bolt.
