How long are the screws in Solplanet Solar inverter wall-bracket side fixing screws?

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 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 Solplanet Solar inverter wall-bracket side fixing screws?

The source lists a Phillips PH2 drive. Standard M4 heads otherwise take PH2 (Phillips) or T20 (Torx), or 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 Solplanet Solar inverter wall-bracket side fixing screws be?

The source gives 1.6 Nm for two M4 screws, PH2 driver, 1.6Nm torque; length not stated.

M4 · length not stated in the sources

Our records put Solplanet Solar inverter wall-bracket side fixing screws on M4 screws. None of the sources we found gives an exact length, so measure the original before you order.

The record covers two M4 screws, PH2 driver, 1.6Nm torque; length not stated.

Head and drive, as the source states them: Phillips PH2 drive.

This entry is marked reported and comes from solplanet.net.

For reference, M4 is 4 mm across the threads at 0.7 mm pitch. The imperial size people confuse it with: #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). If yours measures noticeably more or less, it is a different thread.
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.
Driver: the source names a Phillips PH2 drive. For comparison, standard M4 heads take PH2 (Phillips) or T20 (Torx), or a 3 mm hex key.

Common mix-ups with M4

Festo sensor brackets are named after the sensor interface (DASP-M4-...), but the bracket's own fixing screws are often a different size (M5/M6/M8).
Display mounts mix systems: the screen side is metric M4/M6, but the wall side of many mounts uses imperial wood screws such as #14 x 2.5in.
