REELY KS3 Clamping Discs for Shafts (10 Pack)

These REELY KS3 clamping discs provide a secure push-on retention solution for 3 mm shafts in model building and RC applications. Unlike traditional retaining rings that require special tools or grooves, these spring steel discs snap directly onto smooth shafts, holding components firmly in place with simple manual pressure.

Highlights

• Fits 3 mm shafts with 7.5 mm outer diameter
• Spring steel construction for reliable clamping force
• Pack of 10 discs for multiple assemblies
• Tool-free installation by hand

In daily use

Slide the disc onto the shaft and push it to the desired position. The spring steel grips the shaft without damaging it, preventing wheels, gears, or collars from sliding off. Ideal for quick adjustments and repairs where a permanent fastener is not needed.
