VXB flight controller anti-vibration standoffs screw size
M3 · length not stated in the sources
If you are replacing a screw on VXB flight controller anti-vibration standoffs, the thread is M3. None of the sources we found gives an exact length, so measure the original before you order.
It is listed for naze32/CC3D/F3/F4 FPV stack hardware.
This entry is marked confirmed and comes from vxb.com.
M3 means a 3 mm nominal diameter with a 0.5 mm thread pitch. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Vibration loosens small screws on drones and RC models, so builders commonly add a drop of medium (blue) threadlocker on metal-to-metal joints — never on plastic.
- Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.5 mm from one thread crest to the next (20 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- Driver: the source does not name the drive. Standard M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- Tightening: no device-specific torque is published in these records. The site's general figure for M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M3
- Nylon M3 standoffs are for vibration isolation, not load-bearing frame arms.
- Thor Zone Nanoq S case mixes metric M3 (various lengths: 4, 5, 6, 10, 13, 20mm) and imperial #6-32 UNC fasteners across the same build, so builders must sort hardware carefully rather than assuming an all-metric kit.

Questions about VXB flight controller anti-vibration standoffs screws
- What size screw does VXB flight controller anti-vibration standoffs use?
- M3 for naze32/CC3D/F3/F4 FPV stack hardware.
- How long are the screws in VXB flight controller anti-vibration standoffs?
- None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
- What is the thread pitch of an M3 screw?
- 0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.
- What screwdriver do I need for VXB flight controller anti-vibration standoffs?
- The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take a 2.5 mm hex key.
- Can I use an imperial screw instead of M3?
- No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.
