Screwdriver Bit Wiha 284

Wiha 284 screwdriver bits set contains two Phillips bits manufactured from high-quality chromium-vanadium (CVM) steel with through hardening for long service life. Each bit has a hexagonal shank for secure seating and simple handling; the bits are finished in a titanium-silver color and laser-etched with size markings. Total length of each bit is 150 mm and the set weight is 32.2 g.

Advantages

The CVM steel construction and through-hardening increase durability and wear resistance. Hexagonal shanks provide reliable retention in bit holders and reduced slipping during use. Laser-etched output sizes ensure quick identification, and the titanium-silver finish improves corrosion resistance and visual clarity of markings.

Suitable for

• General assembly and repair work with Phillips screws
• Use with bit holders, impact drivers, and cordless screwdrivers that accept 1/4" hex shanks
• Maintenance tasks in workshops, construction sites, and household repairs

How to use

For power tools use moderate speed and controlled pressure to prevent damage to screw heads or bits.

Recommendations

Store bits in a dry place and keep them in a bit holder or organizer to protect the laser markings and prevent corrosion. Inspect bits before use and replace any that show significant wear or deformation to maintain secure fastening.
