FingerTech Twist Hubs Thin (pair) 3mm x 0.50"

• Foam wheels are the preferred choice for combat robots because they absorb impacts and save your drive motors from stripping teeth. • Use Twist Hubs to mount our FingerTech Foam Wheels, or if you already have Lite Flites (or their thinner counterpart Lectra Lites) they can be used with Twist Hubs too! • With Twist Hubs, you can easily and securely mount these foam tires to your robot. • The foam tire is held tightly by a custom locking washer, which must be pressed in and turned 90 degrees to release. • The hub is secured to the motor shaft by a strong 8-32 setscrew. • Available with 3mm and 4mm shaft bore, but can be drilled out as big as 6.35mm (0.25in). • Make sure to choose the correct Thin/Wide size to match your wheels. Specifications: Width 0.50". Shaft Bore 3mm. Can be drilled out as big as 6.35mm (0.25in). Weight: Thin size (0.50in wide) 5.6g each. Anodized 6061 aluminum for high strength and low weight. The foam tire is held tightly by a custom locking washer, which must be pressed in and turned 90 degrees to release. The hex flange will allow you to keep driving even if the locking washer is destroyed. The hub is secured to the motor shaft by a strong 8-32 setscrew.  Requires: - 5/64in hex wrench - Foam wheels (FingerTech Foam Wheels, Lite Flites or Lectra Lites) - Needle Nose Pliers or FingerTech Twist Hub Key
