Strobe-enhanced microscopy stage (Wenzel Lab open hardware) screw size
M3 · 20 mm long
Our records put Strobe-enhanced microscopy stage (Wenzel Lab open hardware) on M3 screws, 20 mm long.
It is listed for M3 x 20mm stainless steel screw listed in mechanical parts.
This entry is marked confirmed and comes from wenzel-lab.github.io.
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
- Do not confuse metric mounting screws with the 1/4-20 or 3/8-16 tripod threads that cameras and clamps also carry.
- 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 20 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
- Thor Zone Nanoq S case mixes metric M3 (various lengths: 4, 5, 6, 10, 13, 20mm) and imperial #6-32 UNC fasteners across the same build, so builders must sort hardware carefully rather than assuming an all-metric kit.
- Camera and tripod mounting threads themselves are imperial 1/4in-20 or 3/8in-16 — the metric M2-M4 screws in rig kits are only for the accessory hardware, not the tripod mount.

Questions about Strobe-enhanced microscopy stage (Wenzel Lab open hardware) screws
- What size screw does Strobe-enhanced microscopy stage (Wenzel Lab open hardware) use?
- M3 × 20 mm for M3 x 20mm stainless steel screw listed in mechanical parts.
- How long are the screws in Strobe-enhanced microscopy stage (Wenzel Lab open hardware)?
- The record gives 20 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 Strobe-enhanced microscopy stage (Wenzel Lab open hardware)?
- 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.
