QualGear QG-KIT-VA-3IN-B Projector Mounting Kit screw size
M3 / M4 / M5 / M6 · 4 to 10 mm long
QualGear QG-KIT-VA-3IN-B Projector Mounting Kit takes M3, M4, M5 and M6 metric screws in lengths from 4 to 10 mm.
There are 4 separate fitment records for it, including universal projector plate hardware kit explicitly specifies M3 x 8mm screws (M3), kit specifies M4 x 10mm projector mounting screws (M4) and kit specifies both M5 x 4mm (standoff) and M5 x 10mm projector mounting screws (M5), plus 1 more in the table below.
4 of the 4 records are marked confirmed, drawn from 1 source (media.digikey.com).
An M3 screw is 3 mm in diameter with a 0.5 mm pitch, tapped with a 2.5 mm drill; imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- VESA holes are threaded inserts in the back cover; if a screw stops early, back it out rather than forcing it, because a bottomed-out screw can crack the panel housing.
- Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). This device also uses M4 / M5 / M6, so measure each screw rather than assuming they match.
- 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.
- The records span 4–10 mm, which means different positions take different lengths — match each hole to its own screw.
- 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 / M4 / M5 / M6
- Suunto dive computer service manuals reference strap pins and battery compartment springs but do not explicitly cite a metric screw thread size in the sections reviewed; do not infer M2/M2.5 fitment for Suunto dive computer straps without direct confirmation.
- VESA thread size is set by pattern class: M4 for 75x75/100x100, M6 or M8 for the big 200mm+ patterns. Check the plate on the back of the display.
- The 'GoPro thread' is M5-0.8, a de facto standard on third-party mounts, and is not the imperial 1/4-20 tripod thread.
- VESA display mounts are M4, M6 or M8 depending on the pattern size; measure before ordering.

Questions about QualGear QG-KIT-VA-3IN-B Projector Mounting Kit screws
- What size screw does QualGear QG-KIT-VA-3IN-B Projector Mounting Kit use?
- M3 × 8 mm for universal projector plate hardware kit explicitly specifies M3 x 8mm screws; M4 × 10 mm for kit specifies M4 x 10mm projector mounting screws; M5 × 4–10 mm for kit specifies both M5 x 4mm (standoff) and M5 x 10mm projector mounting screws; M6 × 10 mm for kit specifies M6 x 10mm projector mounting screws for larger thread pattern projectors.
- How long are the screws in QualGear QG-KIT-VA-3IN-B Projector Mounting Kit?
- The records range from 4 to 10 mm depending on the position, so match each screw to its own hole.
- 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 QualGear QG-KIT-VA-3IN-B Projector Mounting Kit?
- 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.
- Where can I buy replacement screws for QualGear QG-KIT-VA-3IN-B Projector Mounting Kit?
- TechSpareWarehouse (our own store) lists M3 x 8mm, which matches the length in the records above.
