Lithium/prismatic battery pack terminals screw size
M6 · length not stated in the sources
The screws used on Lithium/prismatic battery pack terminals are M6. None of the sources we found gives an exact length, so measure the original before you order.
The record covers M6 and M8 terminal posts are the common thread on prismatic lithium cells.
This entry is marked reported and comes from ufinebattery.com.
For reference, M6 is 6 mm across the threads at 1 mm pitch. The imperial size people confuse it with: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6.

How to check the screw before you buy
- Take one original screw out first and measure it before ordering; the record above tells you the thread, the original screw tells you the exact length and head.
- Diameter: across the threads an M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 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 M6 heads take PH3 for Phillips and T30 for Torx, and a 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 M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.

Questions about Lithium/prismatic battery pack terminals screws
- What size screw does Lithium/prismatic battery pack terminals use?
- M6 for M6 and M8 terminal posts are the common thread on prismatic lithium cells.
- How long are the screws in Lithium/prismatic battery pack terminals?
- 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 M6 screw?
- 1 mm (coarse), which is the standard pitch for M6 machine screws; a 0.75 mm fine pitch exists but is uncommon. The tap drill is 5 mm and the normal clearance hole is 6.6 mm.
- What screwdriver do I need for Lithium/prismatic battery pack terminals?
- The sources do not name the drive. For M6, Phillips heads normally take PH3 and Torx heads T30; socket heads take a 5 mm hex key.
- Can I use an imperial screw instead of M6?
- No. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6. Use a true M6 screw so it does not cross-thread or strip the hole.
