KEB COMBIVERT F6 elevator drive (frame size 2) screw size

M4 · length not stated in the sources

Our records put KEB COMBIVERT F6 elevator drive (frame size 2) on M4 screws. None of the sources we found gives an exact length, so measure the original before you order.

Where it is used: protective earth (PE) ground connection screws.

This entry is marked confirmed and comes from kebamerica.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.

How to check the screw before you buy

  1. If several screws hold the same part, check that they are all the same length before assuming they are.
  2. 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.
  3. 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.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. 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.
  6. Tightening: no device-specific torque is published in these records. The site's general figure for M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.

Common mix-ups with M4

  • Grounding-lug screws on Siemens and Beckhoff gear (M4) are earth hardware, not structural mounting screws — don't reuse them to hold a module.
  • Grounding/earth-stud screws on hazardous-area (ATEX/IECEx) gas detectors are commonly M4 even though the enclosure body uses larger threaded glands — don't extrapolate the earth screw size to the whole unit.

Questions about KEB COMBIVERT F6 elevator drive (frame size 2) screws

What size screw does KEB COMBIVERT F6 elevator drive (frame size 2) use?
M4 for protective earth (PE) ground connection screws.
How long are the screws in KEB COMBIVERT F6 elevator drive (frame size 2)?
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 KEB COMBIVERT F6 elevator drive (frame size 2)?
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.
