Sungrow SBP4K8 battery screw size
M4 / M5 / M6 · length not stated in the sources
Our records put Sungrow SBP4K8 battery on M4, M5 and M6 screws. None of the sources we found gives an exact length, so measure the original before you order.
There are 3 separate fitment records for it, including M4 screw with OT6-4 terminal for the grounding cable, torque 1.6 Nm (M4), four M5 screws for the anchors and four M5 top cover screws, torque 3.0 Nm (M5) and four M6 screw sets secure the power cables (M6).
3 of the 3 records are marked confirmed, drawn from 1 source (file.support.sungrowpower.com).
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.

One row per fitment record. Head, drive and torque are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

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 M5 / 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.
- 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 / M5 / M6
- TV mount screw size follows the VESA pattern, not the brand — the same maker's small and large sets need M4, M6 or M8.
- Carbon bosses strip easily: 2-4 Nm torque and the right length so the bolt doesn't bottom out.
- Rack hole threads vary: 10-32 and 12-24 are still common in US racks alongside M6 - check the rail before buying.

Questions about Sungrow SBP4K8 battery screws
- What size screw does Sungrow SBP4K8 battery use?
- M4 for M4 screw with OT6-4 terminal for the grounding cable, torque 1.6 Nm; M5 for four M5 screws for the anchors and four M5 top cover screws, torque 3.0 Nm; M6 for four M6 screw sets secure the power cables.
- How long are the screws in Sungrow SBP4K8 battery?
- 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 Sungrow SBP4K8 battery?
- 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 Sungrow SBP4K8 battery be?
- The source gives 1.6 Nm for M4 screw with OT6-4 terminal for the grounding cable, torque 1.6 Nm.
