Can a manufacturer make a custom screwdriver bit size?

Yes. A screwdriver manufacturer can make custom bit sizes and tip profiles for OEM or special repair applications, provided the required dimensions and screw geometry are clearly defined.

Custom bit development can include:

Non-standard Hex sizes

Custom Slotted width and thickness

Special Phillips or cross-head dimensions

Custom Pentalobe or Tri-point profiles

Special socket or hollow-ground tips

Custom bit length

H4 / 4 mm or H6.35 / 6.35 mm shank

Special recess depth or tip geometry

Magnetic or non-magnetic versions

S2, CR-V, or other suitable steel materials

For custom bits, the most important information is:

Screw drawing or dimensional data

Across-flats, width, thickness, or diameter

Tip depth and profile

Required bit length

Working torque

Target screw material

Expected order quantity

If possible, we recommend providing the actual screw or a physical sample. This allows the factory to verify fit, machining tolerance, and torque performance before mass production.

For ToolQeen OEM projects, custom screwdriver bits can be developed according to the buyer’s target screw, dimensions, material, hardness, shank size, length, and application, followed by sample fit and torque testing before production.
