SICK BEF-AP-EPA universal sensor adapter bracket screw size
M4 · 10 mm long
The screws used on SICK BEF-AP-EPA universal sensor adapter bracket are M4, 10 mm long.
The record covers supplied with 3x M4x10 Allen screws (part 2045400).
Head and drive, as the source states them: Hex socket (Allen) drive.
This entry is marked confirmed and comes from sick.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 names a Hex socket (Allen) drive. For comparison, standard M4 heads take PH2 (Phillips) or T20 (Torx), or a 3 mm hex key.
- 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
- Festo sensor brackets are named after the sensor interface (DASP-M4-...), but the bracket's own fixing screws are often a different size (M5/M6/M8).
- On sensors, an "M4" or "M12" marking often describes the sensor barrel or connector thread, not the mounting screw - check which one the datasheet means.

Questions about SICK BEF-AP-EPA universal sensor adapter bracket screws
- What size screw does SICK BEF-AP-EPA universal sensor adapter bracket use?
- M4 × 10 mm for supplied with 3x M4x10 Allen screws (part 2045400).
- How long are the screws in SICK BEF-AP-EPA universal sensor adapter bracket?
- 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 SICK BEF-AP-EPA universal sensor adapter bracket?
- The source lists a Hex socket (Allen) drive. Standard M4 heads otherwise take PH2 (Phillips) or T20 (Torx), or 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.
