Loose wheel nuts are one of those small frustrations that can end a bash session early. You finish a pack, then notice a wheel wiggling or a nut missing. The Apex RC Products Orange 4mm Aluminum Serrated Nylon Locknut Wheel Nut Set #9803 is a direct answer to that problem: a simple set of locknuts designed to stay put on your 1/10 scale RC.
Quick verdict
At USD 11.99, this 10-piece set gives you a handful of locknuts designed to resist backing off with a dual-action locking mechanism. For RC drivers running popular 1/10 scale cars and trucks from brands like Traxxas, Redcat, HPI, or ECX, it's a straightforward way to refresh your wheel hardware and add a visible pop of color.
Who it suits
This set is for hobbyists who want a fresh wheel nut option without changing their setup. If you're ready to swap out your current hardware for something with a locking design, these fit that need. Having a few spares in your toolbox during maintenance is a plus.
What stands out from the listed details
Two features pull their weight here. The serrated base works with the nylon collar to resist loosening. Together, they give the nut a dual layer of security. The orange anodized finish makes these nuts easy to spot during a quick pre-run check, and the lightweight build keeps rotating mass down.

What you're getting is a 10-pack of 4mm aluminum locknuts with a serrated base and nylon insert. The locking design is the main reason to pick these up, and the orange finish adds visibility. The trade-off is the specific 4mm thread size: if your axles don't match, these won't work for your car.
Meaningful trade-offs
The biggest thing to watch is fit. The product is described for most 1/10 scale vehicles from Traxxas, Redcat, HPI, ECX, and more, but that leaves room for exceptions. Before you buy, it's wise to confirm the 4mm thread size on your specific model. That's the difference between a simple install and a part that sits unused.
Bottom line
For USD 11.99, the Apex RC Products Orange 4mm Aluminum Serrated Nylon Locknut Wheel Nut Set #9803 is a practical add-on for 1/10 scale RC owners. Just be sure your axles use 4mm threads. If they do, these nuts offer a colorful, security-minded upgrade for a very common RC annoyance.
