Tornillos InLine para HDD/SSD de 3,5 pulgadas, 3 mm, cabeza avellanada, plateado, 100 uds.

InLine 77781A screws are designed for secure mounting of 3.5" HDD and SSD drives. These metal countersunk screws feature a flat, 3 mm head, M3 thread and a total length of 4 mm with a 5 mm head diameter, supplied in a pack of 100 in a silver finish.

Advantages

The screws provide reliable fixation for hard disk drives and solid-state drives thanks to their M3 thread and consistent dimensions. Made of durable metal with a flat countersunk head, they sit flush in drive bays and reduce the risk of protruding screw heads. The 100-piece pack ensures a sufficient spare quantity for multiple installations or replacements.

Suitable for

• Mounting 3.5" HDDs in desktop PC cases
• Securing 3.5" form-factor SSDs and adapters
• Replacements during drive upgrades or repairs

How to use
