## Long description

Screw InLine 77781B for 3.5" HDD/SSD is a countersunk fastener with a flat (M3) head designed for secure mounting of 3.5" hard disk drives and solid-state drives in computer hardware. The screw measures 4 mm in length with a 5 mm head diameter and comes in a pack of 1000 pieces with a durable silver finish.
Advantages
The M3 thread and flat countersunk head allow the screw to sit flush with drive bays and mounting brackets, reducing interference with adjacent components. A 4 mm shaft length and 5 mm head diameter provide compatibility with standard 3.5" HDD/SSD mounting holes. The silver finish increases corrosion resistance and supports long-term reliability in typical computer environments.
Suitable for
Mounting 3.5" HDDs in desktop PCs and servers

How to use
