STERIS surgical/sterilization equipment self-tapping screw screw size
M2.5 · length not stated in the sources
Our records put STERIS surgical/sterilization equipment self-tapping screw on M2.5 screws. None of the sources we found gives an exact length, so measure the original before you order.
The record covers "SELF TAPPING SCREW-M2.5" (part 10054782) sold as an OEM STERIS service part.
This entry is marked confirmed and comes from shop.steris.com.
M2.5 means a 2.5 mm nominal diameter with a 0.45 mm thread pitch. Imperial look-alike: #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
- Keep material and finish the same as the original (often stainless) on equipment that is cleaned or sterilised.
- 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
- Commonly confused with imperial 4-40 screws in older medical equipment, but modern GE/Mindray devices explicitly list M2.5 metric threads.
- M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.

- How long are the screws in STERIS surgical/sterilization equipment self-tapping screw?
- 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 M2.5 screw?
- 0.45 mm (coarse), which is the standard pitch for M2.5 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.05 mm and the normal clearance hole is 2.9 mm.
- What screwdriver do I need for STERIS surgical/sterilization equipment self-tapping screw?
