M3×3mm HDD Caddy Screws - 2.5" SATA SSD Hard Drive Mounting Screws
M3×3mm HDD Caddy Screws - 2.5" SATA SSD Hard Drive Mounting Screws is backordered and will ship as soon as it is back in stock.
These M3×3mm machine screws are the correct replacement fasteners for 2.5-inch HDD and SSD caddy mounting in laptops and drive bays. Compatible with SATA hard drives and solid-state drives, these caddy screws ensure secure installation without the fitment issues caused by incorrect screw sizes.
These Phillips flat head carbon steel machine screws are engineered specifically for 2.5-inch hard drive caddy mounting applications requiring M3 × 3mm fasteners.
The M3 × 3mm size is commonly specified for 2.5-inch HDD and SSD caddy installations but is frequently confused with similar metric sizes like M2.5 or M3 × 4mm. Using incorrect screw sizes can result in stripped threads, loose mounting, drive vibration, or damage to the caddy assembly. The short 3mm length is critical for proper engagement without bottoming out or protruding through thin caddy materials.
This exact M3 × 3mm specification ensures proper thread engagement, secure drive retention, and reliable performance in laptop upgrade and replacement scenarios. The carbon steel construction with black finish provides durability and corrosion resistance, while the Phillips flat head design sits flush with caddy surfaces for clean installation in tight enclosures.

How to Choose the Correct Screw
How to Choose the Correct Screw
Selecting the correct screw is important for proper fit, strength, and long-term reliability. Before ordering, confirm the following:
Screw Size (Diameter)
Measure the outer thread diameter of the screw. Metric screws are labeled in millimeters, such as M2, M2.5, or M3.
Length
Measure from under the head to the tip of the screw unless otherwise specified by the head style.
Thread Type
Ensure the thread matches the receiving material. Most electronics and hardware applications require metric machine threads rather than self-tapping threads.
Head Type
Confirm the head style needed for proper seating, such as flat head, pan head, or button head.
Drive Type
Match the drive type (Phillips, Torx, Hex, etc.) to the tools you plan to use and the torque requirements of the application.
Material & Finish
Choose the appropriate material and finish based on strength, corrosion resistance, and environmental conditions.
If you are replacing an existing screw, we recommend removing one and comparing the diameter, length, and head type directly before ordering to ensure a proper fit.
