Screws, Nuts, Standoffs

Building or repairing an FPV drone or other RC model would be impossible without these small but absolutely crucial mounting components. In this category, you'll find a wide selection of screws, nuts, and standoffs necessary for solidly and safely assembling your build.

We offer essential fasteners used in FPV and RC:

• Metric Screws: Most commonly in M2 and M3 sizes, in various lengths and with different head types (e.g., socket head cap, button head, flat/countersunk). Available in steel (black oxide, stainless), lightweight aluminum (often anodized colors), or durable titanium.
• Nuts: Standard hex nuts and, very importantly in models subject to vibration, self-locking nylon insert nuts (nyloc). Available in various sizes (M2, M3, M5 for props) and materials.
• Standoffs: Spacing pillars, most often used for mounting the electronics stack (FC/ESC). Available with M2 or M3 threads, in various heights (e.g., 20mm, 25mm, 30mm), and made of aluminum (often knurled and colored) or lightweight nylon. Come in female-female or male-female versions.

Having a stock of basic screws, nuts, and standoffs in your workshop helps avoid downtime during builds or repairs.

Choosing the right fasteners is crucial for the durability and safety of the structure. Pay attention to:

• Thread Size (M2, M3, M5...): Must match the holes in the frame, motors, flight controller, etc. The standard for 5-inch and larger FPV drones is M3 (stack mounting, arms, sometimes motors). Smaller drones often use M2. M5 thread is typical for propeller nuts.
• Screw Length: This is a very important parameter! The screw must be long enough to securely engage the thread (at least a few turns), but must not be too long to, for example, hit motor windings underneath or damage a PCB. Always measure the required length carefully or check frame/motor specs. It's worth having various lengths on hand.
• Screw Head Type: Choose based on the application – socket cap or button heads are most common. Flat/countersunk heads are needed for flush mounting (e.g., bottom frame plate).
• Material: Steel (usually black oxide or stainless) is standard – strong and inexpensive. Aluminum is lighter and comes in colors but is less strong. Titanium offers the best strength-to-weight ratio but is more expensive. Nylon is very lightweight and non-conductive but has the lowest strength.
• Nut Type: For mounting components subject to vibration (e.g., motors, props), always use self-locking (nyloc) nuts to prevent them from loosening.
• Standoff Height and Thread: Height (e.g., 20mm, 25mm) determines the spacing between stack boards or frame plates. The thread must match the screws used (M2 or M3).

Using screws and nuts of the appropriate type and size is fundamental for a solid build.

Anyone who has built a drone knows the feeling – missing that one specific M3x8mm screw, or a lost nyloc nut... Small hardware items can halt an entire project. Wondering what exact size standoffs you need for your stack? Looking for lightweight nylon screws?
