Keystone stainless hex standoff (P/N 24295) screw size
M3 · 10 mm long
Our records put Keystone stainless hex standoff (P/N 24295) on M3 screws, 10 mm long.
It is listed for PCB standoff.
This entry is marked confirmed and comes from Keystone 24295 datasheet.
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
- Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
- 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 10 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
- Intel's ATX and microATX specs never state a metric standoff thread; PC motherboard standoffs are usually imperial 6-32, and PC fan screws are commonly 6-32 self-tapping.
- Motherboard screws must not poke past the standoff and touch traces on the back of the board.

Questions about Keystone stainless hex standoff (P/N 24295) screws
- What size screw does Keystone stainless hex standoff (P/N 24295) use?
- M3 × 10 mm for PCB standoff.
- How long are the screws in Keystone stainless hex standoff (P/N 24295)?
- 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 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 Keystone stainless hex standoff (P/N 24295)?
- 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.
- Where can I buy replacement screws for Keystone stainless hex standoff (P/N 24295)?
- TechSpareWarehouse (our own store) lists M3 x 10mm, which matches the length in the records above.
