MikroTik MTAD-5G-30D3-PA parabolic dish screw size
M4 / M6 · 12 to 20 mm long
MikroTik MTAD-5G-30D3-PA parabolic dish takes M4 and M6 metric screws in lengths from 12 to 20 mm.
There are 2 separate fitment records for it, including M4 x 12 bolts with serrated washers, qty 4, torque about 2 Nm (M4) and M6 x 20 feed bracket bolts, qty 8, torque about 5 Nm at the nut (M6).
2 of the 2 records are marked confirmed, drawn from 1 source (getic.com).
An M4 screw is 4 mm in diameter with a 0.7 mm pitch, tapped with a 3.3 mm drill; imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

How to check the screw before you buy
- Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
- Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). This device also uses M6, 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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 12–20 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.
Common mix-ups with M4 / M6
- Curved or textured monitor backs often need spacers or washers to clear the arm clamp.
- Manual gives torque only, not screw length/drive type — verify physically before sourcing replacements.
- No screw length given, only torque — measure existing hardware before replacing.
- Rack hole threads vary: 10-32 and 12-24 are still common in US racks alongside M6 - check the rail before buying.

Questions about MikroTik MTAD-5G-30D3-PA parabolic dish screws
- What size screw does MikroTik MTAD-5G-30D3-PA parabolic dish use?
- M4 × 12 mm for M4 x 12 bolts with serrated washers, qty 4, torque about 2 Nm; M6 × 20 mm for M6 x 20 feed bracket bolts, qty 8, torque about 5 Nm at the nut.
- How long are the screws in MikroTik MTAD-5G-30D3-PA parabolic dish?
- The records range from 12 to 20 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 MikroTik MTAD-5G-30D3-PA parabolic dish?
- 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.
- How tight should the M4 screw on MikroTik MTAD-5G-30D3-PA parabolic dish be?
- The source gives 2 Nm for M4 x 12 bolts with serrated washers, qty 4, torque about 2 Nm.
