Mini Screwdriver Set Cross/Slotted Driver Hand Tools Transparent Handle 75~150mm

For eyeglasses and watches, the 3×75 mm variant is typically the right fit — the narrow 3 mm shaft engages the tiny M1–M2 screws common in frames and watch bands, and the short 75 mm length gives you precise fingertip control in confined spaces.

Cross (Phillips) drivers have a four-point star tip designed for Phillips-head screws, which are the most common type in electronics and appliances. Slotted (flat-head) drivers have a single flat blade for straight-slot screws. Check your fastener head before selecting a style to avoid damaging the screw.

Yes. The 3 mm and 5 mm shaft diameters are well-suited for the small Phillips and slotted screws found in laptops, game controllers, and other consumer electronics. The transparent handle allows you to monitor shaft alignment, which helps prevent cam-out on sensitive circuit-board fasteners.

Match the shaft diameter to the screw head size: 3 mm shafts suit M1–M2 screws, 5 mm shafts suit M2.5–M3 screws, and 6 mm shafts suit M3.5–M4 screws. If the tip wobbles in the slot or cross recess, size down; if it won't seat fully, size up. When in doubt, contact us to confirm compatibility.

Yes. The 5×75 mm and 5×100 mm variants are popular for model kit and RC assembly because they provide enough shaft length to reach recessed screw points while remaining short enough for controlled torque. The 10-piece packs are a cost-effective way to keep spares at the workbench.

For a single technician bench, a 3-piece or 5-piece pack of each size covers daily use and provides backups. For a shared workshop or classroom setting, the 10-piece pack offers the best per-unit value and ensures tools are always available. Mix and match sizes and quantities using the variant selectors above.

The transparent plastic handles can tolerate light wiping with isopropyl alcohol (IPA) for general cleaning. Avoid prolonged exposure to acetone or strong solvents, which can cloud or weaken the plastic over time. Contact us to confirm compatibility with specific cleaning agents used in your environment.
