Conjunto de chaves de fendas Wera Big Pack 900 Kraftform 05133285001

The Wera Big Pack 900 Kraftform 05133285001 is a set of 13 straight screwdrivers designed for professional and DIY use. Each screwdriver features the multi-component Kraftform handle for comfortable, low-exertion work and an integrated hex bolster that accepts an open-jaw or ring spanner to transfer greater torque. The blades are made from high-quality bit material and run through the handle to ensure full force transmission, and the hexagonal non-roll feature prevents the tools from rolling away.

Advantages

The Kraftform handle reduces hand fatigue and improves grip. An integrated impact cap increases service life and lowers the risk of blade splintering when struck. The through-hardened hexagon blade resists breaking and permits safe force transfer. The hex bolster allows use with a spanner for additional torque, and the non-roll shape keeps screwdrivers in place on work surfaces.

Suitable for

• General assembly and maintenance tasks
• Electrical and mechanical repairs requiring Phillips, Pozidriv, slotted (Sit) and Torx tips
• Professional workshops and DIY projects
• Applications where additional torque is needed using a spanner

How to use

If striking is necessary, use the impact cap and always wear protective goggles.

Recommendations

Use the correct tip type and size to avoid damaging screw heads. Keep the blades clean and inspect handles and tips before use. Wear eye protection when striking the handle and avoid using the screwdrivers as chisels or pry bars.
