Screwdriver Bit Set Wera 05073342001 3 pcs Hex 4 5 6 mm

The Wera 05073342001 3-piece screwdriver bit set contains three hex (Allen) bits in sizes 4 mm, 5 mm and 6 mm, supplied in a blister pack for compact storage and easy access. Manufactured by Wera, the bits are intended for use with compatible bit holders, ratchets and manual or powered drivers that accept standard hex bits. The design focuses on precise fit and resistance to wear for repeated fastening and loosening of hex-headed fasteners.

Advantages

Each bit is made to provide a close tolerance fit with hex sockets to minimise cam-out and rounding. The small, consistent dimensions and hardened material offer improved durability compared with generic bits. The blister packaging keeps the three bits organized, visible and protected while remaining easy to store or carry in a toolbox or on a workbench.

Suitable for

• Assembly and maintenance of furniture and cabinets with hex fasteners
• Mechanical and light industrial fastening tasks requiring 4, 5 or 6 mm hex bits
• Repair and maintenance of bicycles, machinery and equipment with Allen bolts
• Use with bit holders, ratchets, T-handles or power drivers that accept hex bits

Key specifications

• Bit type: Hex (Allen) screwdriver bits
• Sizes included: 4 mm, 5 mm, 6 mm
• Quantity: 3 pieces
• Packaging: Blister pack for storage and visibility
• Material properties: hardened steel construction for wear resistance

How to use

Select the hex bit matching the fastener size (4, 5 or 6 mm). Insert the bit securely into a compatible bit holder, screwdriver, ratchet adapter or power driver. Engage the bit fully into the fastener recess before applying torque to reduce the risk of stripping. When using power tools, apply steady, controlled torque and avoid excessive force to preserve the bit tip and the fastener head. After use, return the bits to the blister pack or store them in a suitable bit organizer.

Usage recommendations

Use the correctly sized bit for each fastener and ensure the bit is fully seated before turning. For high-torque applications, use an appropriate ratchet or torque-controlled driver rather than relying solely on a screwdriver handle or power tool without torque control. Inspect bits periodically for wear or deformation and replace them if signs of rounding or damage appear to maintain safe and effective fastening.
