Conjunto de chaves de fendas manuais Wiha 31499

The Wiha 31499 Manual screwdriver set includes a SYSTEM 4 ESD handle with interchangeable blades that extend to reach low-lying screws in electronic components. The set’s SYSTEM 4 blades can be adjusted to lengths between 18 and 90 mm and are compatible with Wiha SYSTEM 4 interchangeable blades (series 269). The click-stop ball clamp secures blades firmly, while the SoftFinish® handle shape supports ergonomic grip during precision electronics work. The handle meets IEC 61340-5-1 and has a dissipative surface resistance between 10^6 and 10^9 ohm to safely channel electrostatic energy away. A robust roll-up bag keeps tools compact and organized.

Advantages

The interchangeable SYSTEM 4 blades provide flexibility to set the required blade profile and length quickly and securely, enabling work on recessed or hard-to-reach screws. The click-stop ball clamp ensures stable blade retention. The dissipative ESD handle complies with IEC 61340-5-1, offering controlled discharge of static to protect electronic components. The ergonomically contoured SoftFinish® handle reduces hand strain during precision tasks, and the roll-up bag saves storage space and keeps the set organized.

Suitable for

• Precision electronics assembly and repair
• Fastening low-lying or recessed screws in devices
• Work requiring ESD protection (static-sensitive components)
• Technicians who need a compact, interchangeable screwdriver set

How to use

Insert the desired SYSTEM 4 interchangeable blade into the handle and secure it using the click-stop ball clamp until it locks. Adjust blade length as required within the 18–90 mm range. Use the appropriate blade profile (Hex, Phillips, Slot, Torx) for the screw head and apply controlled torque suitable for precision electronics. After use, retract or remove blades if needed and store the handle and blades in the roll-up bag to protect tips and keep the set compact.

Recommendations

For safe handling of static-sensitive components, ensure the ESD handle is used in conjunction with other ESD-safe workplace measures (wrist strap, grounded workbench) and select the correct blade profile and length to avoid cam-out or damage to screw heads.
