Quick answer
If you lost the thumb screw or hex screw from your Out Front Bike Mount, buy the Screw Set. If you need to mount an action camera or accessory to the bottom of the mount, buy the Accessory Mount Set.
Two different jobs, two different kits
Both replacement parts are made for the Peak Design Out Front Bike Mount, but they solve completely different problems. One restores the mount's core clamping function; the other adds a new mounting point. Choosing the wrong kit leaves you with hardware you can't use.
Trade-offs at a glance
- Screw Set (1780384): Replaces the two screws that secure your phone or case to the mount. Comes with a hex wrench.
- Accessory Mount Set (1780381): Provides the hardware to attach action cameras or accessories to the bottom of the mount. Does not include screws for the phone clamp.
- Key trade-off: The Screw Set fixes a broken clamp; the Accessory Mount Set adds a new feature. Neither kit can do the other's job. Check what is actually missing or broken before ordering.
