Fluke Y2638 rack-mount kit (2638A data acquisition) screw size
M6 · length not stated in the sources
The screws used on Fluke Y2638 rack-mount kit (2638A data acquisition) are M6. None of the sources we found gives an exact length, so measure the original before you order.
Where it is used: rack faceplate and screw plate fasten through the rack with six M6 hex/panhead screws.
Head and drive, as the source states them: pan head.
This entry is marked confirmed and comes from media.fluke.com.
For reference, M6 is 6 mm across the threads at 1 mm pitch. The imperial size people confuse it with: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6.

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 M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- Driver: the source does not name the drive. Standard M6 heads take PH3 for Phillips and T30 for Torx, and a 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 M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M6
- Rack hole threads vary: 10-32 and 12-24 are still common in US racks alongside M6 - check the rail before buying.
- TS-Optics Losmandy-style dovetail bars drill through-holes sized to accept either M6 metric screws or 1/4" imperial screws interchangeably in the same countersunk holes.

Questions about Fluke Y2638 rack-mount kit (2638A data acquisition) screws
- What size screw does Fluke Y2638 rack-mount kit (2638A data acquisition) use?
- M6 for rack faceplate and screw plate fasten through the rack with six M6 hex/panhead screws.
- How long are the screws in Fluke Y2638 rack-mount kit (2638A data acquisition)?
- 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 M6 screw?
- 1 mm (coarse), which is the standard pitch for M6 machine screws; a 0.75 mm fine pitch exists but is uncommon. The tap drill is 5 mm and the normal clearance hole is 6.6 mm.
- What screwdriver do I need for Fluke Y2638 rack-mount kit (2638A data acquisition)?
- The sources do not name the drive. For M6, Phillips heads normally take PH3 and Torx heads T30; socket heads take a 5 mm hex key.
- Can I use an imperial screw instead of M6?
- No. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6. Use a true M6 screw so it does not cross-thread or strip the hole.
