SRP TITANIUM MIDDLE/OUTER FIXING BOLT SET

This set of five titanium fixing bolts and nuts replaces the standard steel ones that come with many cranksets. The bolts are threaded with the standard 8mm by .75mm threads. The threaded portion of the bolt is 8.5mm long. A question should arise about how Titanium can be used for both the nut and bolt pieces of this set without them "seizing" to each other as the bolt is threaded into the nut.

The answer is the bolt pieces should be coated with an anti-seize compound. The bolt head has a 5mm hex fitting. The nuts are also made of titanium with a slot cut in the back for a grip at time of removal. The threaded portion of the nut 8.5mm long. The five bolts weigh 7 grams, while the five nuts weigh 6 grams, making a set weight of 13 grams. While aluminum nut and bolt sets have occasionally been known to "strip out," with serious pressure, during installation, Titanium bolt sets have known no such failure.
