Flanged Lock Nut 5x8mm (4) (ARAC9698)

Flanged lock nuts with M5 threads, sold in a four-pack. They’re designed to secure wheel hubs and other hardware in hobby kits, delivering a tight, vibration-resistant fit. A nylon insert helps prevent loosening, while the large serrated flange bites into the surface for a secure grip. Tightening is done with an 8 mm hex key.

Durable and precise, these lock nuts are ideal as replacement parts for kit items. They use a standard M5 thread, include a nylon insert to resist loosening, and rely on a serrated flange to anchor into the wheel surface. The four-pack keeps you prepared for ongoing maintenance.
