Where did that wrench go? These quick-change thumb screws are a simple, high-impact upgrade for anyone who uses the Vevor faceting machine regularly.

Every factor knows the moment when a basic adjustment turns into a fight with the hardware. These knobs strip that friction out of your workflow. Fewer tools on the bench. Fewer parts to misplace. Faster transitions between laps and mast positions.

The design upgrades the stock Vevor mast and lap nuts, letting you swap laps or reposition the mast by hand. Each knob has a deep knurled surface that stays grippy even when wet, and the press-fit metal insert matches the factory hardware for a clean, confident feel.

Sold as a set.
Use with factory hardware; nuts are not included.
