Head styles & standards cross-reference

  • Socket cap (cylindrical head)ISO 4762 / DIN 912M3 socket cap, the default engineering hex-drive screw
  • Low-head socket capDIN 7984 / ISO 7380-style low profileReduced head height — the usual choice where a standard cap head would foul
  • Button headISO 7380-1Domed low head, common on 3D printers, cages and brackets
  • Countersunk (flat) socketISO 10642 / DIN 799190° head, sits flush in a chamfered hole
  • Pan head PhillipsISO 7045 / DIN 7985 (JIS B 1111 in Japanese gear)Most consumer-electronics service screws are this family
  • Countersunk PhillipsISO 7046 / DIN 965Flush pan-equivalent for plastics and covers
  • Pan / countersunk TorxISO 14583 / ISO 14581Used where higher torque or tamper resistance is needed

Supplier part numbers

Fastener suppliers build codes from style + size + length + material rather than a single universal number. These are the patterns to search with.

  • McMaster-Carr91290A### (alloy socket cap), 92095A### (flat head), 92005A### (pan Phillips)Catalog families for metric M3 — the trailing digits pick the exact length
  • AccuSSC-M3-6-A2 (socket cap), SPP-M3-6-A2 (pan Phillips)Accu part codes are built as style-thread-length-material
  • Bossard / WürthISO 4762 M3x6 A2-70European distributors order by standard + size + material grade, not a fixed SKU
  • RS / Farnell / Digi-Key"M3 x 6mm" + head style + material in the parametric filterStock codes differ per region — search by the standard instead

Watch out for

  • M3 (3.0mm, 0.5mm pitch) is not #6-32 UNC (~3.5mm) — they look identical and cross-thread, the single most common PC-building mistake.
  • 3.5in drives and 5.25in bays are 6-32; 2.5in drives and motherboard standoffs are M3. Keep the two bins apart.
  • Raspberry Pi holes are M2.5, not M3 — forcing M3 means reaming the hole and risking a cracked board.
  • Post-2018 3.5in drives have shallower bottom holes; an over-long screw can puncture the drive housing.
  • Motherboard screws must not poke past the standoff and touch traces on the back of the board.
  • 2020 extrusion T-nuts come in M3/M4/M5 and are not interchangeable — M3 is accessory-only, M5 is structural.
  • Camera tripod and Arca threads are imperial 1/4-20 and 3/8-16, never M3.
  • Nylon M3 standoffs are for vibration isolation, not load-bearing frame arms.
  • PC drive bays and expansion slots often use imperial 6-32, not M3, despite looking the same (https://www.intel.com/content/www/us/en/support/articles/000005567/boards-and-kits.html)
  • Extrusion T-nuts for one slot size come in M3, M4, M5 and M6 — match the nut to your bolt, not just the slot (https://www.tnutz.com/product/st-020/)
  • LED strip clips strip easily — M3x12 into thin plastic should be hand-driven, never with a power driver.
  • CPAP teardowns rarely state thread size; M3 here is inferred from photos and small-appliance convention, not a spec sheet.
  • Sonos speakers mix lengths within one unit — M3 for driver housings, M2.5 at the control panel. Keep them sorted during teardown.
  • M3 is the most common FPV screw, but length must match arm and stack thickness — too long can short motor windings or crack frame plates.
  • Eurorack cases mix M3 (most common) and M2.5 rails — check the case brand before buying in bulk.
  • ISO 14581 Torx countersunk screws look like plain countersunk screws but need the right lobe driver; a Phillips bit will chew the head.
  • Terminal-block clamp screws have manufacturer-specific torque values — over-tightening cracks the block or crushes the wire.
  • Server drive caddy screws (Dell, HP) are usually M3 in very short lengths (3-4mm) because they bite into thin sheet metal — they are NOT the 6-32 UNC screws that go into the drive's own side holes.
  • DIN-rail terminal blocks are near-universally M3 across Dinkle, TE, Omron and RND, but torque differs (0.5-0.8 Nm) — over-torquing an M3 terminal screw strips it instantly.
  • US-made guitar bridges use #4/#6 imperial intonation screws while imported bridges use M3 — the wrong one strips the saddle.
  • Firearms red-dot mounting plates use M3 screws across many patterns (Vortex Viper, Burris FastFire, Swampfox) at a common 12 in-lb torque spec, but exact screw length/head style varies by footprint and is not interchangeable without checking the specific pattern sheet. (https://www.sportshooter.de/shop/downloads/6925/RED-DOT-PATTERN-INSTALLATION-INSTRUCTIONS.pdf)
  • Elo's optional security screw kits for its touchscreens use M3x6, a much shorter/smaller fastener than the M4 VESA mounting screws on the same unit — the two thread sizes coexist on one device for different purposes (VESA mount vs. anti-tamper). (https://docs.elotouch.com/MS602782.pdf)
  • ARRMA vehicles mix M3x0.35mm fine-pitch and M3x0.5mm coarse-pitch button-head screws across different sub-assemblies (e.g., shock mounts), so an M3 tap/die or replacement screw is not universally interchangeable within the same model line. (https://www.arrmaforum.com/threads/screw-pitch-confusion.71918/)
  • Many red-dot mounting-screw guides (Trijicon RMR, Holosun 407C/507C, Leupold DeltaPoint Pro) specify imperial 6-32 or 5-40 UNC threads, not metric, per https://legion-precisionweaponsystems.com/red-dot-mounting-screws-size-and-torque-guide-for-glock-slides-trijicon-holosun-leupold/ and https://www.trijicon.com/TorqueSpecs — do not assume M3 for all pistol-slide optics.
  • Driver-bit-only mentions (e.g. Torx sizes referenced in forum threads like https://www.sigtalk.com/threads/torx-driver.411194/) are not sufficient on their own to confirm thread size without the corroborating engineering drawing/manual.
  • M3 is by far the most common metric fastener across lab, metrology, and cleanroom equipment, spanning coarse-thread ISO M3x0.5 in most cases.
  • Cleanroom/vacuum-rated M3 screws (titanium, vented, low-outgas) from NBK are a distinct specialty class, priced and sourced very differently from commodity M3 hardware — do not substitute one for the other in semiconductor fixtures.
  • Eurorack is a strong known case with two competing metric standards (M2.5 for Vector rails, M3 for Schroff/DIN-style and 3U threaded rails); mixing rail types requires matching screw/nut thread.
  • Some sewing-machine screws are labeled with metric-looking but slightly nonstandard sizes (e.g. M3.3) that are not true ISO M3 and are not interchangeable with standard M3 hardware.
  • Generic MRO/hardware-catalog listings (e.g. RAF M3x.5 captive panel screws, thumb screws) are real metric-confirmed parts but are not tied to a specific device in any of the target categories, so they were excluded from the device-fitment list despite confirming M3x0.5 is a common captive-panel screw pitch used across enclosures generally.
  • Search-engine snippet for Notifier 002-439 Instruction Manual states installers must remove 'three M3 screws' securing the back-box cover of a fire alarm multi-mount enclosure. Could not directly render/view the full source page (JavaScript-rendered site returned no static HTML text), so this is reported only, not independently confirmed by direct page inspection — treat as unverified until the live PDF/manual is opened directly.
  • Many vendor pages for elevator controllers (KEB Combivert F6 lift manual), PLC/IO modules (Phoenix Contact, Beckhoff), KNX/BACnet gateways, HVAC controllers, circuit breakers (ABB SACE Tmax XT), fire alarm panels (Autronica BS-100, C-TEC CFP, XFP, Notifier NFS), and enclosure hardware (Rittal AE, Wöhner busbar supports, IDEC/TE/Rockwell terminal blocks) were checked but did NOT contain an explicit metric thread callout in the retrieved text (only wire gauge, torque-only-without-thread, driver-bit type, or generic 'screw connection' language) — these were excluded per the strict-evidence rule rather than guessed.
  • Sewing machine needle clamp/plate screws are frequently cross-listed by imperial-sounding part numbers and generic 'sewing machine screw' listings; only vendor pages that explicitly print the metric callout (e.g., M3x3, M4 x 6mm) should be trusted, since many aftermarket screw kits do not state true thread size at all.
  • Thor Zone Nanoq S case mixes metric M3 (various lengths: 4, 5, 6, 10, 13, 20mm) and imperial #6-32 UNC fasteners across the same build, so builders must sort hardware carefully rather than assuming an all-metric kit.
  • Thorlabs' 16mm cage system standard plates use dual 4-40 (UNC) and M3 taps on the same plate (e.g., SP01), so metric and imperial fasteners are both valid depending on the region/kit purchased.
  • Many gas-detector and sensor manuals only give a torque spec (e.g. '0.5 N·m max') without repeating the thread size at every mention — the explicit M3 callout is usually only in the accessories/spare-parts table, not the main installation steps.
  • Grub screws (set screws) on sensor retainers are frequently M3 even when the surrounding housing uses M4/M5 fasteners — don't assume one thread size for a whole enclosure.
  • Eurorack rail thread varies by manufacturer: some tapped M2.5, some M3 — not a single universal standard.
  • GRAS manual says 'Screw 3 mm' without the 'M' prefix, so treated as reported rather than fully confirmed metric-thread callout.
  • Printer manuals often mix screw callouts like 'M3*8L' (length in mm after the L) with driver-bit-only references elsewhere in the same manual — only the explicit M-prefixed entries were captured here.
