Ponta sextavada Wera 840/9 C 1,5 mm Halfmoon 44 mm — ponta de chave de fendas, sextavada 1,5 mm, comprimento 44 mm

The Wera Hex Bit 840/9 C Halfmoon 1.5 mm, 44 mm is a precision screwdriver bit engineered for small hex fasteners where accurate fit and controlled torque transfer are required. With a 1.5 mm hex tip and a 44 mm overall length, this bit enables access to shallow recesses and confined spaces while maintaining reliable engagement with compatible bit holders, multi-bit screwdrivers, and ratchets. The Halfmoon profile aids positioning and reduces the risk of cam-out during delicate assembly tasks.

Advantages

This hex bit is manufactured to close tolerances to ensure consistent tip geometry and long-term fit with 1.5 mm hex screws. The 44 mm length gives extended reach compared with standard short bits while remaining compact for maneuverability. The Halfmoon design improves centring in tiny recesses and supports accurate torque application. Its compatibility with common bit holders and ratchet adapters provides flexible use across handheld and powered driver systems.

Suitable for

• Electronics assembly and repair where 1.5 mm hex fasteners are used
• Precision mechanical assembly such as instrument and optical device maintenance
• Tight or shallow recesses where a 44 mm bit provides better access than a short bit
• Use with bit holders, ratchet adapters, and multi-bit screwdrivers

Key specifications

• Tip type: 1.5 mm hex (halfmoon profile)
• Overall length: 44 mm
• Material and hardness: engineered for wear resistance and torque transmission
• Compatibility: standard 1/4" bit holder interfaces and common screwdriver bit systems

How to use

Select the Wera 1.5 mm hex bit and insert it securely into a compatible bit holder, ratchet adapter, or multi-bit screwdriver. Engage the hex tip with the corresponding screw head, ensuring the Halfmoon profile seats fully in the recess before applying torque. Apply steady, controlled force appropriate to the fastener and assembly material to avoid stripping. For power-assisted driving, use low torque settings and intermittent operation to preserve tip geometry and prevent over-tightening.

Recommendations

Inspect the bit tip before use and replace if rounded or worn. Use the bit with the correct holder size and avoid excessive side loads. Store dry to prevent corrosion and keep away from impacts that can deform the tip.
