J-GUANG 2EDGKM-7.62 high-current power terminal block screw size
M4 · 10 mm long
The screws used on J-GUANG 2EDGKM-7.62 high-current power terminal block are M4, 10 mm long.
It is listed for guide explicitly states 'M4 Screw — 1.2 Nm... IEC 60999-1 Standard... used in 7.62mm pitch terminal blocks... for high-current power distribution, motor controls, and inverter outputs'.
This entry is marked confirmed and comes from nbjge.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
- Board standoffs and enclosure bosses set the usable length: the screw should clamp the board without bottoming in the standoff.
- 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.
- The record states 10 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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
- M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.

Questions about J-GUANG 2EDGKM-7.62 high-current power terminal block screws
- What size screw does J-GUANG 2EDGKM-7.62 high-current power terminal block use?
- M4 × 10 mm for guide explicitly states 'M4 Screw — 1.2 Nm... IEC 60999-1 Standard... used in 7.62mm pitch terminal blocks... for high-current power distribution, motor controls, and inverter outputs'.
- How long are the screws in J-GUANG 2EDGKM-7.62 high-current power terminal block?
- The record gives 10 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 J-GUANG 2EDGKM-7.62 high-current power terminal block?
- 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 J-GUANG 2EDGKM-7.62 high-current power terminal block be?
- The source gives 1.2 Nm for guide explicitly states 'M4 Screw — 1.2 Nm... IEC 60999-1 Standard... used in 7.62mm pitch terminal blocks... for high-current power distribution, motor controls, and inverter outputs'.
