When you are bashing a 1/10 scale RC truck or buggy, the last thing you want is a wheel nut working loose mid-run. The decision often comes down to finding a locknut that fits your axle thread, keeps its grip through vibration, and does not add unnecessary weight. The Apex RC Products Red 4mm Aluminum Serrated Nylon Locknut Wheel Nut Set is one such option, and it comes in a 10-pack. For USD 11.99, you get a set of ten nuts that are described as being made from lightweight aluminum and featuring serrations plus a nylon insert to help prevent backing off.
Quick Verdict
If your 1/10 scale RC car or truck uses 4mm wheel nuts, this set from Apex RC Products is a practical, low-fuss choice. The nylon-insert locknut design is a familiar way to keep hardware snug, and the aluminum construction keeps weight down. At USD 11.99 for ten pieces, it gives you enough nuts for two vehicles, with a couple of spares left over.
Who It Suits
This set is aimed at owners of 1/10 scale RC vehicles that take 4mm wheel nuts. The product details specifically mention fitment with popular brands such as Traxxas, Redcat, HPI, and ECX, along with many others. If that matches your model, the ten-count pack is convenient for someone who runs more than one vehicle or wants spares already on hand.
What Stands Out from the Listed Details
The biggest practical highlights are the anti-backout features. The serrations on the nut and the nylon collar work together to resist loosening from vibration, which is exactly what you want on a wheel that sees constant acceleration, braking, and rough terrain. The aluminum build is also worth noting because it keeps the hardware light, and the red anodized finish adds a bit of visual pop to your hubs.
Meaningful Trade-Offs
The main limitation is that this is a 4mm wheel nut specifically. If your RC uses a different axle thread size, this set will not be the right match. There is also no mention of a wrench size or whether the nut is compatible with all wheel types, so you will want to confirm that 4mm is the correct thread for your axles before ordering. The ten-nut pack is more than a single vehicle needs, which is fine if you plan to use the extras, but it is not the bare-minimum pack if you only need four.
Bottom Line
The Apex RC Products Red 4mm Aluminum Serrated Nylon Locknut Wheel Nut Set #9804 is a solid pick for RC owners who know their vehicle takes a 4mm locknut. The combination of serrations, nylon insert, and lightweight aluminum addresses the common problem of wheels loosening during use. At USD 11.99, the 10-pack gives you good coverage for one or two vehicles, and the red color makes it easy to spot. Just confirm your thread size first, and this set should do the job.
Apex RC Products Red 4mm Aluminum Serrated Nylon Locknut Wheel Nut Set #9804
This is the product in question. It includes ten wheel nuts, each listed with serrations and a nylon insert to help prevent backing off, and it is constructed from lightweight aluminum. The set is described as fitting most 1/10 scale RC cars and trucks from popular brands like Traxxas, Redcat, HPI, ECX, and many more. The price is USD 11.99 for the 10-piece set. The 4mm thread size is the key specification to match against your vehicle, and it is the main factor that will determine whether this is the right purchase for you.
