Makita 1806B planer screw size
M4 / M5 · 12 to 75 mm long
Makita 1806B planer takes M4 and M5 metric screws in lengths from 12 to 75 mm.
There are 2 separate fitment records for it, including two pan head screws in the housing/handle assembly (M4) and multiple pan head screws across housing and handle in three lengths (M5).
Head and drive, as the sources state them: pan head.
2 of the 2 records are marked confirmed, drawn from 1 source (makita.sk).
M4 means a 4 mm nominal diameter with a 0.7 mm thread pitch. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.
Makita 1806B planer screw specifications
One row per fitment record. Head, drive are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

| M5 | 12–75 mm | 0.8 mm | Pan head | not stated | Multiple pan head screws across housing and handle in three lengths | Confirmed |

How to check the screw before you buy
- Check the strength class stamped on the head (8.8, 10.9, A2-70) and replace like for like.
- Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). This device also uses M5, so measure each screw rather than assuming they match.
- Pitch: 0.7 mm from one thread crest to the next (14.29 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 12–75 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 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 M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4 / M5
- Not all telescope/finder hardware is metric — Celestron Edge/NexStar SE finder-shoe and dovetail screws are reported as 8/32 (imperial UNC), so metric M4/M5 fitments cannot be assumed across all Celestron products; must check per accessory/vintage.
- US-made pinball machines (Williams/Bally/Stern) overwhelmingly use imperial UTS threads (#6-32, #8-32, #10-32); explicit metric threads only appear on newer/import components such as Jersey Jack Pinball's Hobbit Smaug assembly (M3).
- Espresso/coffee-equipment M5 and M6 socket-head screws (DIN 7984/UNI 9327) are cross-brand standard fasteners shared across CMA, Astoria, and La Cimbali brewing-group hardware, so a single screw often services multiple manufacturers' machines.
- Husqvarna alone mixes M5 (trimmer and chainsaw housings) and M6 (brushcutter/mower housings), so screws are not interchangeable across their own models.

Questions about Makita 1806B planer screws
- What size screw does Makita 1806B planer use?
- M4 × 30 mm for two pan head screws in the housing/handle assembly; M5 × 12–75 mm for multiple pan head screws across housing and handle in three lengths.
- How long are the screws in Makita 1806B planer?
- The records range from 12 to 75 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M4 screw?
- 0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
- What screwdriver do I need for Makita 1806B planer?
- The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
- Can I use an imperial screw instead of M4?
- No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
