Brand new set of 4 TITANIUM stem bolts.  * Threading: M8 X 1.25 * Length: 24mm (threaded portion only - overall length is 31.1mm) * Fits: Most any stem with metric threading (usually made in Japan or Taiwan) made in the past 20+ years (which is most stems). * Finish: BLACK (by PVD, physical vapor deposition) * Material: TITANIUM  * Grade 5 (6AL-4V) * Weight: Just under 7 grams per bolt (26 grams per set of 4 - compared to a steel set of 4 stem bolts which weighs 55 grams) * Has built in washers to prevent damage to your aluminum stem when tightening. * TORQUE TO MAXIMUM 20 ft-lbs (be sure your professional installer knows this is the maximum torque). * EXTRA SMALL diameter head (only 10mm diameter to fit piston stems and others with tight recessed clearance) As always, measure carefully before ordering.
