Wiha 284 Screwdriver Bit

The Wiha 284 screwdriver bit is a precision tool made for reliable fastening and torque transfer. The bit features a high-quality CVM steel blade that is through-hardened for durability and is finished in titanium silver with laser-etched size markings. With Torx tips T20 and T25, a 150 mm overall length and a hexagonal shank, this Wiha 284 bit provides a secure fit and convenient handling for a variety of fastening tasks.

Advantages

The through-hardened CVM steel construction increases wear resistance and maintains tip geometry under repeated use. Titanium silver finish and laser-etched output sizes improve visibility of markings. The hexagonal shank ensures a positive drive connection and compatibility with standard bit holders, while the 150 mm length offers extended reach without adding significant weight (32 g).

Suitable for

• Precision assembly and disassembly requiring Torx T20 and T25
• Electronics, appliances and mechanical maintenance
