Tyco/Advanced MX1 fire panel loop card kit (FP0950) screw size
M3 · 10 mm long
If you are replacing a screw on Tyco/Advanced MX1 fire panel loop card kit (FP0950), the thread is M3, 10 mm long.
The record covers hex barrel nut FA2016, 4.76 A/F, spaces loop card off backplane.
This entry is marked confirmed and comes from tycosafetyproducts-anz.com.
For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- On vehicles and bikes, use the original strength class and finish; outdoor hardware is usually stainless or coated to resist corrosion.
- 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.
- The record states 10 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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
- Model rocketry altimeter manuals (Apogee AIM USB, Rocketronics AltiMAX G4, RockeTiltometer) contain no explicit metric screw thread callouts in their documentation; mounting is typically via hook-and-loop or generic standoffs, so no metric fitment can be confirmed for this category.
- M3 (3.0mm, 0.5mm pitch) is not #6-32 UNC (~3.5mm) — they look identical and cross-thread, the single most common PC-building mistake.

Questions about Tyco/Advanced MX1 fire panel loop card kit (FP0950) screws
- What size screw does Tyco/Advanced MX1 fire panel loop card kit (FP0950) use?
- M3 × 10 mm for hex barrel nut FA2016, 4.76 A/F, spaces loop card off backplane.
- How long are the screws in Tyco/Advanced MX1 fire panel loop card kit (FP0950)?
- The record gives 10 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 Tyco/Advanced MX1 fire panel loop card kit (FP0950)?
- 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 Tyco/Advanced MX1 fire panel loop card kit (FP0950)?
- TechSpareWarehouse (our own store) lists M3 x 10mm, which matches the length in the records above.
