Eaton 93PX UPS/EBM/MBP (15-20 kVA) screw size
M3 / M4 / M5 / M6 · length not stated in the sources
The screws used on Eaton 93PX UPS/EBM/MBP (15-20 kVA) are M3, M4, M5 and M6. None of the sources we found gives an exact length, so measure the original before you order.
There are 4 separate fitment records for it, including signal/control terminal screws on UPS, EBM (battery module) and MBP, tightening torque 0.8 (M3), wiring/control terminal screws, tightening torque 1.6 Nm per torque table (M4) and power/output terminal screws, tightening torque 3.0 Nm per torque table (M5), plus 1 more in the table below.
4 of the 4 records are marked confirmed, drawn from 1 source (kompleksmedia.pl).
An M3 screw is 3 mm in diameter with a 0.5 mm pitch, tapped with a 2.5 mm drill; imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

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 M3 screw measures about 3 mm with calipers (usually a hair under). This device also uses M4 / M5 / M6, so measure each screw rather than assuming they match.
- 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.
- 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 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.
Common mix-ups with M3 / M4 / M5 / M6
- Many gas-detector and sensor manuals only give a torque spec (e.g. '0.5 N·m max') without repeating the thread size at every mention — the explicit M3 callout is usually only in the accessories/spare-parts table, not the main installation steps.
- Camera rig/cage accessories (SmallRig, Wooden Camera/Metabones) frequently mix M4 structural screws with 1/4-20 and 3/8-16 imperial mounting points on the same product — verify which specific fastener a manual is referencing before ordering replacements.
- Carbon bosses strip easily: 2-4 Nm torque and the right length so the bolt doesn't bottom out.
- Manual explicitly warns that under-tightening this M6 hinge screw can let the door glass crash into the drum, so torque compliance matters more than just thread match.

Questions about Eaton 93PX UPS/EBM/MBP (15-20 kVA) screws
- What size screw does Eaton 93PX UPS/EBM/MBP (15-20 kVA) use?
- M3 for signal/control terminal screws on UPS, EBM (battery module) and MBP, tightening torque 0.8 Nm per torque table; M4 for wiring/control terminal screws, tightening torque 1.6 Nm per torque table; M5 for power/output terminal screws, tightening torque 3.0 Nm per torque table; M6 for main battery/power terminal screws (labelled M6 at connection points 2.2 and 3.4), tightening torque 5.0 Nm per torque table.
- How long are the screws in Eaton 93PX UPS/EBM/MBP (15-20 kVA)?
- 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 Eaton 93PX UPS/EBM/MBP (15-20 kVA)?
- 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.
- How tight should the M3 screw on Eaton 93PX UPS/EBM/MBP (15-20 kVA) be?
- The source gives 0.8 Nm for signal/control terminal screws on UPS, EBM (battery module) and MBP, tightening torque 0.8 Nm per torque table.
