What are H6.35 screwdriver bits?

H6.35 screwdriver bits are bits with a 6.35 mm hexagonal shank, which is the standard 1/4-inch hex bit size widely used in manual screwdrivers, ratchet screwdrivers, electric screwdrivers, drills, and impact-compatible holders.

The main characteristics are:

6.35 mm / 1/4-inch hex shank: compatible with many standard bit holders and quick-change systems

Higher torque capacity: stronger and more suitable for general repair, assembly, furniture, appliances, and mechanical work

Wide bit selection: available in Phillips, Slotted, Torx, Security Torx, Hex, Pozidriv, Square, and other profiles

Different lengths: common lengths include approximately 25 mm, 40 mm, and 45 mm

Easy replacement: the standardized shank makes it simple to change bits between different tools

Compared with H4 / 4 mm precision bits, H6.35 bits are larger and better suited for higher-torque applications. H4 bits are normally preferred for phones, laptops, cameras, watches, and other small electronics.

For ToolQeen screwdriver projects, H6.35 bits can be configured with different tip profiles, lengths, S2 or CR-V materials, hardness levels, ratchet handles, cases, and private-label packaging for OEM and wholesale orders.
