TKR5571A 12mm Aluminum Clamping Wheel Hex Set (4)

The TKR5571A 12mm Aluminum Clamping Wheel Hex Set is an upgraded wheel hex set designed for Tekno RC 1/10 and 1/8 platforms that use 12mm SCT-style wheel systems, including vehicles like the SCT410, SCT410.3, EB410, ET410, MT410, and compatible SC trucks. Machined from aluminum and hard anodized, these hexes improve strength over stock plastic parts while also adding a clamping design that helps prevent wheel pin loss during high-impact driving. They are a direct replacement for standard 12mm hex hubs and are commonly used in SCT racing and bashing setups where durability and consistent wheel fitment are important.
