Our take on the Shimano Rear Flat Mount Road Caliper Fixing Bolt Snap Retainer

This is a single Shimano fixing bolt for mounting a flat-mount disc brake caliper to a road or gravel frame. It is the rear caliper bolt with a snap retainer, sold one per caliper. It suits riders replacing a lost or damaged bolt or building up a frame that needs flat-mount hardware. Shimano's own hardware is the safe match for its flat-mount calipers, though generic titanium and steel bolt kits offer the same function for less.

Questions and answers

Will this fit my flat-mount caliper?
It is made for Shimano flat-mount disc brake calipers and is the rear caliper fixing bolt. Check that your frame and caliper use the flat-mount standard before ordering.
Is one bolt enough for a bike?
No. It is sold one per rear caliper, and a flat-mount caliper typically needs two bolts, so order the number your setup requires.
What does the snap retainer do?
The retainer is designed to keep the bolt seated against the caliper during installation and service. It does not replace correct torque.
Can I use it on a post-mount caliper?
No. This is a flat-mount fixing bolt and does not fit post-mount calipers, which use a different bolt and spacing.
Do I need threadlocker with it?
Follow Shimano's installation instructions for your caliper. Many setups call for a threadlocker on caliper bolts, so check the manual before fitting.
