LP Gear cartridge mounting screw set screw size
M2.5 · length not stated in the sources
LP Gear cartridge mounting screw set takes M2.5 metric screws. None of the sources we found gives an exact length, so measure the original before you order.
The record covers product description calls it a '2.5mm headshell mounting screw set' i.e. M2.5 thread for phono cartridge-to-headshell mounting.
This entry is marked confirmed and comes from lpgear.com.
For reference, M2.5 is 2.5 mm across the threads at 0.45 mm pitch. The imperial size people confuse it with: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

How to check the screw before you buy
- Where the manufacturer publishes a torque value, use a torque driver rather than feel.
- Diameter: across the threads an M2.5 screw measures about 2.5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.45 mm from one thread crest to the next (22.22 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 M2.5 heads take PH1 for Phillips and T8 for Torx, and a 2 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 M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2.5
- M2 and M2.5 are both marketed for turntable headshells; buyers must check which their specific cartridge/tonearm brand uses.
- Rotrics DexArm's manual calls for an 'M2.5 hex key' - that is the driver size, not the screw thread.
