Bopla DIBLZ distance bolts screw size

M3 · length not stated in the sources

If you are replacing a screw on Bopla DIBLZ distance bolts, the thread is M3. None of the sources we found gives an exact length, so measure the original before you order.

It is listed for distance bolts for plastic enclosure bosses have M3 internal threads.

This entry is marked confirmed and comes from bopla.de.

M3 means a 3 mm nominal diameter with a 0.5 mm thread pitch. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy

  1. Board standoffs and enclosure bosses set the usable length: the screw should clamp the board without bottoming in the standoff.
  2. Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
  3. Pitch: 0.5 mm from one thread crest to the next (20 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 M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 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 M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M3

  • GE patient monitors often use 'PT 3x10mm' screws; these are thread-forming screws for plastic and are NOT standard M3 machine threads.
  • Terminal-block clamp screws have manufacturer-specific torque values — over-tightening cracks the block or crushes the wire.

Questions about Bopla DIBLZ distance bolts screws

What size screw does Bopla DIBLZ distance bolts use?
M3 for distance bolts for plastic enclosure bosses have M3 internal threads.
How long are the screws in Bopla DIBLZ distance bolts?
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 M3 screw?
0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.
What screwdriver do I need for Bopla DIBLZ distance bolts?
The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take a 2.5 mm hex key.
Can I use an imperial screw instead of M3?
No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.
