Hex screwdriver Wera 950 SPKL HF 3 mm — insulated handle, 3 mm hex blade

The Wera 950 SPKL HF 3 mm is a hex screwdriver designed for driving and removing 3 mm hex fasteners with precision. The tool combines a slender 3 mm hex blade with an ergonomic, insulated handle that improves grip and control during assembly, maintenance and repair tasks. The compact design allows access to confined spaces while offering the torque feedback necessary for accurate tightening and loosening of small hex screws used in electronics, machinery and workshop applications.

Advantages

The insulated handle delivers a secure, slip-resistant grip and supports precise torque application for small fasteners. The 3 mm hex blade is slim and accurately machined to fit hex heads closely, reducing cam-out and wear. The overall construction balances durability and maneuverability to suit repeated use in technical and general repair work.

Suitable for

• Assembly and disassembly of small mechanical components
• Electronics and electrical device maintenance (non-live work)
• Routine workshop and machinery servicing
• Precision adjustment tasks in confined spaces

Key specifications

• Blade size: 3 mm hex
• Handle type: ergonomic, insulated for improved grip
• Blade profile: hexagon (internal hex)
• Tool length: compact design for tight access (manufacturer typical compact form)
• Material characteristics: hardened and precisely machined blade for fit and wear resistance

How to use

Select the Wera 950 SPKL HF 3 mm for tasks requiring a 3 mm internal hex. Insert the hex blade fully into the fastener head to ensure a firm engagement. Apply steady, controlled torque while maintaining a perpendicular alignment to the fastener to avoid stripping. Use short, controlled turns when working in confined spaces and verify the fastener engagement frequently to prevent over-tightening. Store the screwdriver in a dry, organized place to protect the blade and handle between uses.

Usage recommendations

Use the insulated handle for improved grip but verify insulation suitability for live electrical work before use; this product is intended primarily for mechanical fastening tasks. For best results, match the screwdriver size exactly to the fastener and avoid using excessive force to prevent damage to the tool and fastener.
