PEM KFE-M3-4ET broaching standoff screw size
M3 · 4 mm long
Our records put PEM KFE-M3-4ET broaching standoff on M3 screws, 4 mm long.
The record covers M3 x 0.5 self-clinching standoff for sheet metal chassis.
This entry is marked confirmed and comes from pemnet.com.
For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
- 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.
- 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.
- The record states 4 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 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.
- 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
- Part numbers can embed a thread code (e.g. ifm fibre fittings with 'M3') that refers to a fitting thread, not a chassis screw.
- The bioprinter M3 reference is a tube-connector thread spec, not a structural chassis screw; verify before assuming interchangeability with fastener screws.

Questions about PEM KFE-M3-4ET broaching standoff screws
- What size screw does PEM KFE-M3-4ET broaching standoff use?
- M3 × 4 mm for M3 x 0.5 self-clinching standoff for sheet metal chassis.
- How long are the screws in PEM KFE-M3-4ET broaching standoff?
- The record gives 4 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 PEM KFE-M3-4ET broaching standoff?
- 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.
- Where can I buy replacement screws for PEM KFE-M3-4ET broaching standoff?
- TechSpareWarehouse (our own store) lists M3 x 4mm, which matches the length in the records above.
