Losi TLR336001 4mm Aluminum Serrated Locknut Set (6) TLE 22/T-SCT-2.0

The Losi TLR336001 is a 4mm aluminum serrated locknut set, sold as a pack of 6, built for the TLR 22/T-SCT-2.0. These locknuts use a serrated aluminum flange design that bites into the mounting surface for extra resistance against loosening under vibration, an upgrade over standard nylon-insert locknuts in terms of both security and weight savings.

They're used at various points across the 22 platform where a secure, lightweight fastener is needed to hold a component in place without the risk of it working loose during hard racing. Standard locknuts can lose their locking ability over repeated removal and reinstallation, so having a fresh set of genuine Losi aluminum locknuts on hand ensures reliable clamping force every time you reassemble a joint. This pack matches the factory 4mm specification used across the 22 platform, so it's a direct, dependable replacement. Keep a set in your toolbox for secure, lightweight hardware wherever you need it.
