Head styles & standards cross-reference

  • Socket cap (cylindrical head)ISO 4762 / DIN 912M4 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 M4 — the trailing digits pick the exact length
  • AccuSSC-M4-6-A2 (socket cap), SPP-M4-6-A2 (pan Phillips)Accu part codes are built as style-thread-length-material
  • Bossard / WürthISO 4762 M4x6 A2-70European distributors order by standard + size + material grade, not a fixed SKU
  • RS / Farnell / Digi-Key"M4 x 6mm" + head style + material in the parametric filterStock codes differ per region — search by the standard instead

Watch out for

  • VESA fixes the hole pattern and max thread depth, not screw length — length depends on the panel back and any spacers.
  • Too long cracks the panel or punctures internals; too short works loose. This is the #1 mounting failure.
  • Curved or textured monitor backs often need spacers or washers to clear the arm clamp.
  • M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.
  • Red dot and pistol optic screws are imperial (#6-48, #6-32, #8-40), not metric, even on optics that use M4 elsewhere (https://legion-precisionweaponsystems.com/red-dot-mounting-screws-size-and-torque-guide-for-glock-slides-trijicon-holosun-leupold/)
  • Appliance panel screws are usually thread-forming into plastic even when they look like M4/M5 machine screws, so they cross-thread easily on refit (https://www.repairclinic.com/RepairHelp/Washer)
  • Samsung TV stand screws (M4) are not the same as wall-mount bolts (M6/M8) — mixing them strips threads (https://electronics.alibaba.com/question/samsung-tv-stand-screw-sizes-m4-vs-m6-guide)
  • Dashcam mounts advertised as '1/4" M4 screw joint' have two different threads: the 1/4"-20 camera thread and a separate M4 grub screw for the ball joint — don't order the wrong one.
  • There is no single standard Picatinny/rail screw size; makers use metric M3/M4 and imperial 6-48 or 8-40 interchangeably. Always measure the existing screw.
  • Smart doorbell and lock kits bundle metric machine screws with imperial wood screws in the same bag; the metric ones are rarely labelled.
  • Pinball machines are historically imperial (UNC/UNF). Metric M4 shows up mainly in specific parts like cooling fans or in European rebuilds.
  • TV mount screw size follows the VESA pattern, not the brand — the same maker's small and large sets need M4, M6 or M8.
  • VESA size follows the hole pattern, not the brand: MIS-D uses M4, MIS-E/F uses M6 or M8.
  • VESA thread size is set by pattern class: M4 for 75x75/100x100, M6 or M8 for the big 200mm+ patterns. Check the plate on the back of the display.
  • D-sub jackscrews come in both metric M3 and imperial 4-40 — identical looking, not interchangeable.
  • Festo sensor brackets are named after the sensor interface (DASP-M4-...), but the bracket's own fixing screws are often a different size (M5/M6/M8).
  • Tesla Wall Connector torque spec table explicitly lists 'M4 screws (x4)' for terminal connections but marks torque as 'N/A', meaning no numeric torque value is given even though the thread size is confirmed — installers must not assume a generic M4 torque applies. (https://energylibrary.tesla.com/docs/Public/More/Powershare/InstallManual/HomeBackup/en-us/GUID-53594456-D583-4DD8-A54C-B672B10340D9.html)
  • Many consumer smart-home devices (Nest thermostats, Ring doorbells) publish only screw length in inches (e.g. '1-1/4in bracket screws') or generic 'mounting screws' without stating a metric thread size, so they had to be excluded despite being physically M3/M4 in most teardown reports. (https://d1kusojqr3t85q.cloudfront.net/jrz4hnnvdyct/qTzlQvU4nV1O2GJpcvZtx/8c17e3784e19f6691250560e3b8280b4/US_Video_Doorbell_Pro_Installation-Manual.pdf)
  • A SIG Talk forum post describes an optic manual calling out an "M4x0.7 Torx head screw" — corroborating but user-reported, not a primary manufacturer document: https://www.sigtalk.com/threads/torx-driver.411194/
  • TE Connectivity customer drawing shows M4X0.7 dimension callout for a connector-type part, not a device mount — included only as generic confirmation that M4x0.7 is a standard metric fastener callout used across electronics/connector engineering drawings, not evidence of a specific device application: https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7FT0931000408000%7FA%7Fpdf%7FEnglish%7FENG_CD_T0931000408000_A.pdf%7FT0931000408-000
  • Standard injection-molded LEGO Technic axles/pins are friction-fit, not threaded; only specialty metal aftermarket axle replacements use real ISO metric threads (M4/M5), and these are not official LEGO parts.
  • Makeblock explicitly discontinued their original 'Socket Cap Screw' in favor of a 'Button Head Socket Cap Screw' with a smaller head, per their hardware pack datasheet -- older BOMs/instructions may reference the retired part.
  • Numerous generic 'U-clip nut' and dashcam/tripod-thread listings claim compatibility with 'car dash/interior' or camera mounts using M4/M5/M6 or 1/4"-20, but none of these pages ties a specific device model to a specific metric size with a stated length — rejected as too generic/inferred.
  • US-made pinball machines (Williams/Bally/Stern) overwhelmingly use imperial UTS threads (#6-32, #8-32, #10-32); explicit metric threads only appear on newer/import components such as Jersey Jack Pinball's Hobbit Smaug assembly (M3).
  • JCM bill-acceptor manual warns that if the host cabinet mounting bracket is only 2mm thick, standard-length M4 screws will not seat correctly — screw length must be matched to bracket thickness.
  • Third-party tripod thread adapters (1/4-20 to M4/M5/M6/M8/M10) are widely sold, confirming M4/M5/M6 tripod mounts exist on some cameras/accessories, but these are aftermarket adapter listings, not OEM service manual statements, so they are excluded from entries per the strict sourcing rule.
  • Not all telescope/finder hardware is metric — Celestron Edge/NexStar SE finder-shoe and dovetail screws are reported as 8/32 (imperial UNC), so metric M4/M5 fitments cannot be assumed across all Celestron products; must check per accessory/vintage.
  • Some rackmount KVM switch kits pair M4x10 bracket-to-rack screws with M3.2x4.5 bracket-to-chassis screws (non-standard M3.2, not a true M3), so kits are not fully interchangeable with generic M3/M4 hardware.
  • OEM laundry-parts storefronts (Alliance Laundry) are a very reliable source because they name the exact DIN standard and thread callout in the product title itself, unlike most service manuals which just show an exploded-view drawing.
  • Grounding/earth-stud screws on hazardous-area (ATEX/IECEx) gas detectors are commonly M4 even though the enclosure body uses larger threaded glands — don't extrapolate the earth screw size to the whole unit.
  • 'Semus' in the Kern manual is a brand/head-style qualifier on the screw, not a separate thread designation — the metric callout is still plainly M4.
  • Pool-robot spare-parts shops sometimes list only a manufacturer part number without a thread size; the Zodiac Vortex 3 listing was chosen specifically because the size (M4×25 mm) is spelled out in the product title/description.
  • Manual gives torque only, not screw length/drive type — verify physically before sourcing replacements.
  • goBILDA is metric M4; the older Actobotics/ServoCity system it resembles is imperial 6-32. The parts look alike and will strip each other.
  • Parts lists that say 'Taptite T-20 screw' are naming the driver, not the thread - only trust the separate M-size callout.
  • Oster and Wahl clipper blade screws are often imperial #6-32, not metric - measure before assuming.
  • The common claim that 75x75 VESA patterns are M4 is not in the VESA standard text - the published spec only defines M6 and M8. Check the display's own manual.
  • Sewing machine screws are often specified in imperial thread (e.g., 9/64"-40 UNC/UNF presser foot screws) even on machines that otherwise use metric M4 needle plate screws, so thread size must be verified per fastener, not assumed uniform across the machine.
  • Power station manufacturers (EcoFlow, Bluetti, Jackery) publish metric screw sizes mainly for external mounting brackets/kits rather than for the main enclosure's internal case screws, so confirmed M4/M5 fitments here apply to mounting hardware, not necessarily the unit's own chassis fasteners.
  • Display mounts mix systems: the screen side is metric M4/M6, but the wall side of many mounts uses imperial wood screws such as #14 x 2.5in.
