TEKTELIC Kona Photon Gen-2 LoRaWAN gateway screw size
M2.5 / M4 / M5 · 8 to 25 mm long
TEKTELIC Kona Photon Gen-2 LoRaWAN gateway takes M2.5, M4 and M5 metric screws in lengths from 8 to 25 mm.
There are 3 separate fitment records for it, including M2.5 x 8mm screws for the SIM tray access-port cover (M2.5), M4 x 0.7 x 12mm ground cable lug bolt, 2.5 Nm (M4) and M5 x 0.8 machine screws in 14mm (radio to solar panel, x6), 24mm (mounting knuckle) and 25 (M5).
3 of the 3 records are marked confirmed, drawn from 1 source (tektelic.com).
An M2.5 screw is 2.5 mm in diameter with a 0.45 mm pitch, tapped with a 2.05 mm drill; 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.

One row per fitment record. Head, drive and torque are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

How to check the screw before you buy
- If several screws hold the same part, check that they are all the same length before assuming they are.
- Diameter: across the threads an M2.5 screw measures about 2.5 mm with calipers (usually a hair under). This device also uses M4 / M5, so measure each screw rather than assuming they match.
- 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.
- The records span 8–25 mm, which means different positions take different lengths — match each hole to its own screw.
- 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.
Common mix-ups with M2.5 / M4 / M5
- M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
- Water heater elements use pipe threads (NPSM/NPT), not metric machine screws.
- Some scooters and appliances use self-tapping screws of similar diameter rather than true M5 machine threads.

Questions about TEKTELIC Kona Photon Gen-2 LoRaWAN gateway screws
- What size screw does TEKTELIC Kona Photon Gen-2 LoRaWAN gateway use?
- M2.5 × 8 mm for M2.5 x 8mm screws for the SIM tray access-port cover; M4 × 12 mm for M4 x 0.7 x 12mm ground cable lug bolt, 2.5 Nm; M5 × 14–25 mm for M5 x 0.8 machine screws in 14mm (radio to solar panel, x6), 24mm (mounting knuckle) and 25mm (arm to bracket), all 2.5 Nm.
- How long are the screws in TEKTELIC Kona Photon Gen-2 LoRaWAN gateway?
- The records range from 8 to 25 mm depending on the position, so match each screw to its own hole.
- 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 TEKTELIC Kona Photon Gen-2 LoRaWAN gateway?
- The sources do not name the drive. For M2.5, Phillips heads normally take PH1 and Torx heads T8; socket heads take a 2 mm hex key.
- Can I use an imperial screw instead of M2.5?
- No. 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. Use a true M2.5 screw so it does not cross-thread or strip the hole.
- How tight should the M4 screw on TEKTELIC Kona Photon Gen-2 LoRaWAN gateway be?
- The source gives 2.5 Nm for M4 x 0.7 x 12mm ground cable lug bolt, 2.5 Nm.
- Where can I buy replacement screws for TEKTELIC Kona Photon Gen-2 LoRaWAN gateway?
- TechSpareWarehouse (our own store) lists M2.5 x 8mm, which matches the length in the records above.
