Unique-Bargains 100 Pcs Laptop Hard Drive Screws M3 x 4mm

Screw Kit for Laptop Drive Bays

This kit supplies one hundred M3 by four millimetre screws designed to secure two-and-a-half-inch hard drives or solid-state drives inside laptop caddies. The parts are compatible with a wide range of notebook brands including Lenovo, IBM, HP, Compaq, Acer and ASUS. They address the common need for replacement fasteners during drive upgrades or repairs. Builders who need longer threads or a different head style will need a separate kit.

Thermal and Power Characteristics

The screws are passive metal fasteners that generate no heat, draw no power and produce no audible noise during operation. Their only physical contribution is the twenty-two gram total mass of the pack. Because they have no electrical or moving parts, there are no thermal limits, fan curves or power-phase considerations to manage. Installers who require conductive thermal pads or active cooling hardware must source those items elsewhere.

Installation Practicalities

The pack contains only the one hundred screws with a two-per-cent count tolerance and no additional brackets, tools or software. The black metal finish resists corrosion and matches typical drive-caddy aesthetics. Each screw provides a four-millimetre male thread length suited to standard drive-mounting holes. Technicians expecting torque-limiting drivers, thread-locking compound or alignment guides will need to supply those separately.
