Product Information

Full details

This Wera Hex-Plus BO Screwdriver Bit is designed for professionals and DIYers working with hexagon socket screws, especially those with a security pin. Its key benefit is the Hex-Plus profile, which significantly reduces cam-out and extends the life of both the bit and the screw head. A minor caveat is its specific use for tamper-proof screws, meaning it won't fit standard hex sockets.

FAQs

What is the main advantage of the Hex-Plus profile?

The Hex-Plus profile provides a greater contact surface area within the screw head, which significantly reduces the notching effect and minimizes the risk of damaging the screw head or the bit.

What does 'BO' stand for in the product name?

'BO' refers to the tamper-proof design, indicating the presence of a protruding pin within the drive profile that prevents standard hex tools from engaging.

Can I use this bit with regular hexagon socket screws?

No, this bit is specifically designed for tamper-proof hexagon socket screws (BO screws) that have a central pin. It will not properly engage with standard hexagon socket screws.

What is the drive size of this bit?

The bit has a 1/4" hexagon drive, suitable for holders conforming to DIN ISO 1173-D 6.3.

What materials is this bit made from?

The bit is made from a tough, viscous material designed for durability and performance with hard materials.

Is this bit suitable for impact drivers?

While designed for toughness, it is primarily intended for use with manual drivers or standard drill/driver chucks, not high-impact applications, unless specified by the tool manufacturer.

Troubleshooting

Bit slips out of the screw head.

Ensure the bit is fully seated in the screw head and that you are using the correct size (6 mm). Check if the screw head itself is damaged.

Difficulty engaging with the screw.

Confirm the screw is a tamper-proof (BO) type with a central pin. Standard hex screws will not engage properly.

Bit appears worn or damaged.

Inspect the Hex-Plus profile for excessive wear. Replace the bit if the profile is significantly degraded to prevent further screw damage.
