K-EDGE Go Big Thumb Screw for Action Camera or Light: Aluminum, Black

The K‑Edge Go Big Thumb Screw is a precision aftermarket thumbscrew designed to secure your action camera, light, or accessory to GoPro‑style bicycle mounts — including combo mounts, camera/light mounts, and other compatible adapters. Made from CNC‑machined aluminum with a built‑in hex wrench feature, this thumb screw gives you both easy manual adjustment and the option to lock it down securely with a 4 mm hex key for a firm connection that resists vibration. Perfect for riders, racers, and content creators who mount lights or cameras on their bike.

Key Features

• Hand‑tight with lock‑down option: Knurled aluminum head lets you tighten or loosen by hand, and the built‑in 4 mm hex bolt lets you torque it down for a secure, vibration‑resistant fit.
• GoPro‑style interface compatibility: Works with GoPro‑style mounts, including K‑EDGE combo and action camera/light mounting systems.
• CNC‑machined 6061‑T6 aluminum: Lightweight yet durable construction stands up to regular use and weather exposure.
• Compact & light: weighs about ~10 g, adding minimal weight to your mount setup.
• Made in the USA & lifetime warranty: Backed by K‑EDGE’s lifetime guarantee against manufacturing defects.

This thumb screw is designed to replace or upgrade the standard fastener on GoPro‑style camera or light mounts — especially when you want more leverage and a more reliable connection on your bike accessories. It’s ideal for securing lights, action cameras, or sensors to your bike mounts without constantly re‑tightening.

A proper mounting screw makes a big difference when your light or camera is subject to vibration, bumps, and long rides. This screw combines easy adjustment with a lockable design so your gear stays put — giving you greater confidence and cleaner footage or lighting on every ride.
