Where to Find Screw Diagrams for Your RC Vehicle

Start with the manual for your exact RC model. Look for a parts drawing that shows each part and where it goes. Use the drawing and parts list to check which screws belong in each spot.

A screw kit gives you parts. The model manual shows how to put those parts together. Before you buy or replace a screw, read the vehicle instructions and the details on the kit's product page.

1. Find your exact model and model number

Find the brand, full model name and model number on the box, manual or vehicle label. Check which version you have, too. Two vehicles can share a name and still use different parts.

If you bought a used vehicle, ask whether the previous owner changed any parts. The maker's manual may not cover those changes. Do not choose a manual or screw kit just because the picture looks right.

2. Look on the vehicle maker's official website

Go to the maker's website and look for Support, Manuals or Downloads. Search with your full model number. Look for the instructions, parts list and parts drawings. You may need more than one file.

Check the model number and version on each file before using it. Save a copy so you can zoom in on small labels while you work.

For an older model, look for a section about models that are no longer sold. If you cannot find the right manual, ask the maker or a hobby shop for help. Give them the full model number. A video or an online discussion can help explain a step, but check it against the correct manual before choosing a screw.

3. Match the drawing to the screw details

Find the part of the vehicle you are working on. Match the labels in the drawing to the parts list. A number beside a screw may help you look it up in the list. It may not tell you the screw's size.

• Check the size: match the thickness and length in the manual. Check whether the sizes use millimeters or inches.

  A digital caliper can help you measure a screw’s diameter and length. Measure the diameter across the outside of the threads. For most screws with a raised head, measure the length from underneath the head to the tip. For a countersunk screw, measure from the top of the head to the tip, including the head. Compare these measurements with the sizes listed in your exact model’s manual. A caliper does not identify the thread type or prove that a screw belongs in a particular hole; also check the manual’s head style and screw type.

• Check the shape: match the top of the screw and any small ring under it. Check how it goes into the part.
• Check the type: a screw made to cut into plastic is different from one used with a metal nut or a hole with matching grooves. Use the type listed in the manual.
• Keep track of each spot: sort the screws you remove in a labeled tray. Take photos as you go.

If a label is unclear or the old screw is missing, ask for help before putting in a new one. A screw that starts turning is not proof that it is the right size or type.

4. Check the kit before you begin

At J-M SUPPLIES RC Parts Store, start with the page for your exact RC model. Open the kit's product page. Read which model it is for, what it includes and what it leaves out. Do not assume that it includes every original part or that kits for similar models use the same parts.

Use a tool that fits the top of the screw. Follow the maker's instructions for putting the parts together and tightening the screws. Do not put glue on screws unless the maker tells you to.

Common questions about RC screw diagrams

Is a screw kit a replacement for the model manual?

No. Use the model manual and parts drawings to find the right screw and where it goes. Read the product page to check what the kit includes. Do not assume it comes with a drawing that shows each screw's place.

Can I use a diagram for a similar model?

Use the manual for your exact model number and version. A similar name or picture does not prove that the screws or their places match.

What if I cannot find my model's manual?

Look for older models on the maker's website. Then ask the maker or a hobby shop for help, using the full model number. Wait until you can find the right part. Do not choose a screw just by looking at it.

Can I replace screws one at a time?

That can help you remember where each screw goes. Follow the steps in the manual, in order. Check that each new screw has the listed size and type. Stop if it will not turn smoothly or the parts do not line up.
