Match the rod length to your access depth. For tight spaces, a shorter rod — 38mm (≈1.5") or 75mm (≈3") — works best. For deep recesses or hard-to-reach fasteners, choose 150mm (≈5.9") to 300mm (≈11.8"). When in doubt, a mid-range 100mm (≈3.9") rod covers most general-purpose tasks.

Cross Head (Phillips-style) is designed for cross-slot screws commonly found in electronics, furniture, and appliances. Flat Head (slotted) fits single-groove screws used in older hardware, electrical panels, and woodworking. Both share the same magnetic tip and extension rod design.

The magnetic tip is designed to hold standard steel screws firmly during insertion, reducing drop risk in overhead or awkward-angle work. It is generally strong enough for everyday fasteners. Very large or heavy screws may require additional support.

These screwdrivers are intended for general indoor and light-duty use. For prolonged outdoor or high-moisture environments, wipe the tips dry after use and store in a dry location to maintain tip condition. Contact us to confirm material finish if corrosion resistance is a priority.

The cross head tip is generally compatible with Phillips (PH) standard screws in sizes typically ranging from PH0 to PH2 depending on the cutterhead diameter selected (3mm, 5mm, or 6mm). The flat head tip fits standard slotted screws in corresponding widths. See variant options for exact cutterhead diameter.

For electronics repair, the 3mm cutterhead with a shorter rod (75mm or 100mm total length) is typically the right choice for precision work on small screws. For furniture assembly or cabinetry, the 5mm or 6mm cutterhead with a longer rod (150mm–300mm) provides better torque and reach for larger fasteners.

Pack quantity varies by variant: 3mm cutterhead sets include 30 pcs, 5mm sets include 12 pcs, and 6mm sets range from 12 to 24 pcs depending on rod length. See the variant selector above for the exact count for your chosen size.
