Screwdriver c.k tools Dextro T49144-035 — blade width 3.5 mm, insulated handle

Hand screwdriver c.k tools Dextro T49144-035 features a 3.5 mm blade width and an insulated handle designed for precision fastening and general DIY or professional tasks that require a narrow tip. The steel blade provides consistent torque transfer while the shaped handle supports controlled turning and reduced slippage. The insulated handle gives additional protection for tasks near live circuits, making this screwdriver suitable for electronics, assembly, maintenance and repair work where a slim, accurate tip is required.

Advantages

The narrow 3.5 mm blade permits access to tight screw heads and small fasteners, enabling accurate alignment and reduced risk of stripping. A shaped, ergonomic handle improves grip and control during repeated use without relying on bulky design elements. The steel blade offers durability and consistent performance under moderate torque, while the insulated handle helps reduce the risk of accidental contact with conductive parts when working near energized components. The compact profile makes the tool easy to store and carry in a technician's toolkit.

How to use

Select the screwdriver for screws that match the 3.5 mm flat blade to ensure correct fit and reduce cam-out. Hold the shaped handle firmly in your dominant hand, position the blade squarely in the screw slot, and apply steady pressure while turning. For work near electrical components, ensure the tool’s insulation is intact and that you follow safe working procedures, including de-energising circuits where possible. Use controlled force appropriate to the screw and material—avoid excessive torque that could damage the fastener or blade.

Usage recommendations

Inspect the blade and handle before each use; replace the tool if the insulation is damaged or the tip is worn. Match the 3.5 mm blade to the screw slot size for optimal engagement. Store the screwdriver in a dry place and keep it separate from power tools to maintain the integrity of the insulated handle.
