How to Choose the Right RC Screw Kit

Choose an RC screw kit by matching your vehicle’s exact model and version, then checking which screws the kit includes. A familiar model name, the same vehicle scale or a high piece count is not enough to confirm a match.

Whether you are replacing a lost screw or planning a rebuild, start with your vehicle manual and a short repair list. This guide from J-M SUPPLIES RC Parts Store explains what to compare before you order.

1. Match your exact vehicle

Find the brand, full model name and manufacturer’s model number in the manual, on the original box or on the manufacturer’s website. Note the version or generation, too.

Two-wheel drive (2WD) and four-wheel drive (4WD) versions can have different hardware. So can vehicles with different chassis—the main frame that supports the parts. A shared body style or model-family name does not confirm that the same kit fits.

Use the RC Model Compatibility Hub at J-M SUPPLIES RC Parts Store to find your vehicle, then compare its model number with the kit listing. If you have changed major parts, check the instructions for those parts as well.

Unsure which version you own? Send the details you have through the RC model help form before ordering.

2. Choose a kit that covers your repair

A kit can be useful for several repairs or a planned rebuild. For one missing screw, an exact replacement may be all you need. Make a short list of the work you want to finish:

One lost or damaged screw: Look up its original part number and size.
Several repairs or a rebuild: Compare the kit’s coverage with the parts of the vehicle you will take apart.
A modified vehicle: Check the hardware required by each changed component. A kit for the original vehicle may not cover it.

Buy for the repair, rather than choosing the box with the most pieces.

3. Compare screw sizes and head styles

Use your vehicle’s manual and exploded drawing—a diagram showing the individual parts and where they fit. Check the screw’s diameter, length, thread type and head style. The head must also fit the space where the screw sits.

The Tekno SCT410 2.0 manual, for example, identifies screws by size, head style, part number and location. Use the manual for your exact vehicle; this example does not confirm that any particular kit fits it.

If a supplied screw differs from the original, check the kit maker’s instructions for that exact use. Do not force a screw that looks close enough.

4. Check what the kit leaves out

A screw kit does not necessarily include every small part on a vehicle. Read the exact listing’s contents and exclusions, including any notes about pins, clips, nuts, washers or tools.

Our RC product FAQs verify we exclude machined collared screws and screw pins. These are special fasteners, so an ordinary screw should not be assumed to replace them.

If sizes, quantities or coverage for the repair you need are unclear, ask before buying. Treat a sample kit photo as an illustration unless the listing confirms it shows that kit’s actual contents.

5. Understand what stainless steel offers

Stainless steel can offer useful corrosion resistance. It is not automatically stronger than every original steel screw. Strength depends on the material and grade being compared.

Bolt Depot’s fastener material guide explains the differences between stainless steel and hardened steel. Follow the vehicle maker’s requirements for the part you are repairing, especially where a particular material or fastener is specified.

6. Check tools before you start

Use the correct driver type and size, with a tip that fits the screw properly. Follow the vehicle and kit instructions for tightening. Stop if the driver slips or the screw will not start as expected.

Use threadlocker only where the instructions call for it. Threadlocker is an adhesive that helps resist loosening; it is not needed on every screw. The Tekno manual above marks its use for that vehicle.

Keep removed screws grouped by the part of the vehicle they came from. Photos taken during disassembly can help when you put it back together.

What model and kit numbers look like on a listing

These two J-M SUPPLIES RC Parts Store listings illustrate the identifiers to compare:

RCScrewZ los152 stainless screw kit: a Losi NASCAR RC Race Car Series listing with LOS11225XX / LOS11224XX model references.
RCScrewZ tra092 stainless screw kit: a Traxxas UDR / Unlimited Desert Racer listing with the 85086-4 model reference.

These are examples of listing details, not a recommendation for your vehicle. Check the current model information and contents. Do not extend a listing’s coverage to a different version or a modified chassis.

Common RC screw kit questions

Can I choose a kit by vehicle scale alone?

No. Scale describes the vehicle’s relative size, but it does not identify the hardware it needs. Match the brand, exact model number and version.

Does a screw kit include bearings?

Do not assume so. J-M SUPPLIES RC Parts Store lists stainless screw kits, rubber-shielded bearing kits and metal-shielded bearing kits as separate part types. Read the exact listing for what is included.

Are stainless screws always stronger than stock screws?

No. Compare the specified materials and follow the requirements for the part of the vehicle you are repairing.

What if I cannot identify a screw?

Check the exact vehicle’s manual and parts diagram. If its size or location is still unclear, ask for help before ordering or installing a substitute.
