{"title":"M3 x 4mm Screws","description":"\u003cp\u003eM3 x 4mm screws are the usual size for fixing 2.5\" SATA SSDs and laptop hard drives into brackets, caddies and NAS drive bays, and for some video-doorbell terminal screws. The short 4 mm length engages the drive threads without reaching the circuit board inside.\u003c\/p\u003e\u003cp\u003eMost 2.5\" drives have four threaded holes on the bottom and four on the sides; which set you use depends on the bracket or caddy. Check the holes with a known M3 screw before you start, and never force a longer screw into a drive. Measure an old screw with calipers: the thread diameter gives the M number and the length gives the second figure. On a countersunk head the length is measured overall, head included; on a flat-bottomed head it is measured from under the head to the tip.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRelated sizes:\u003c\/strong\u003e \u003ca href=\"\/collections\/m3-x-6mm-screws\"\u003eM3 x 6mm\u003c\/a\u003e · \u003ca href=\"\/collections\/m3-screws\"\u003eAll M3 screws\u003c\/a\u003e · \u003ca href=\"\/collections\/hdd-brackets-caddies\"\u003eHDD brackets \u0026amp; caddies\u003c\/a\u003e\u003c\/p\u003e\u003cp class=\"tsw-fitguides\"\u003e\u003cstrong\u003eFit guides:\u003c\/strong\u003e \u003ca href=\"\/pages\/ring-doorbell-screws\"\u003eRing Doorbell screw guide (M3 x 4mm)\u003c\/a\u003e · \u003ca href=\"\/pages\/google-nest-doorbell-screws\"\u003eGoogle Nest Doorbell screw guide (M3 x 4mm)\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"m3-x-4mm-countersunk-phillips-flat-head-screws-for-ssd-hard-drive-10-pack-black","title":"M3 x 4mm Countersunk Phillips Flat Head Screws for SSD Hard Drive 10-Pack Black","description":"\u003ch2\u003eM3 x 4mm Countersunk Phillips Flat Head Screws for SSD Hard Drive | 10-Pack | Black Oxide\u003c\/h2\u003e\u003cp\u003eM3 x 4mm countersunk Phillips flat head screws purpose-built for SSD and hard drive mounting in laptops, desktops, and NAS enclosures.
