TIMco C2 Clamp-Fix Multi-Purpose Screws - 6.0 x 150mm - Yellow

'Timber jacking' is when wood is pushed upwards as a screw is driven. The TIMco C2 Clamp-Fix screws are engineered with specific thread designs and a point that reduces this upward force, ensuring the timbers remain flush and stable during installation.

The patented twin-cut point technology is designed for rapid pick-up and reduced splitting, often eliminating the need for pre-drilling in most timber applications. However, for extremely hard timbers or when working very close to the edge of the wood, a pilot hole may still be beneficial.

The TX30 drive recess provides a more secure and positive engagement with the driver bit compared to other types like Pozidriv or Phillips. This 'Torx' style drive significantly reduces the chance of cam-out (the bit slipping out of the screw head), leading to better control and less damage to the screw head and the surrounding material.

The high-molecular polymer lubricant coating reduces the friction between the screw threads and the timber. This lowers the insertion torque required by up to 52%, making it easier and faster to drive the screws, reducing user fatigue, and minimizing stress on your power tool.

Yes, the screws feature a coating that provides rust protection up to 20 times longer than standard zinc plating, making them highly durable and suitable for demanding professional and DIY applications, including outdoor environments.

The product description does not specify the base material but highlights the advanced coating for durability and rust protection, implying a high-quality steel core suitable for construction.

Ensure you are using a correct and good-condition TX30 driver bit. Apply firm, consistent pressure directly in line with the screw. Avoid over-driving if the screw reaches its desired depth.

Verify you are using a TX30 bit. Check if the timber is unusually dense or has knots. Ensure the drill is set to an appropriate speed and torque setting. The lubricant coating should minimize resistance; if it's still high, inspect the timber for obstructions.

While designed to prevent splitting, very brittle or dry timber, or driving too close to the edge, can still cause minor splitting. Consider a pilot hole in extremely difficult situations or if working very close to the timber's edge.

Ensure the drill is held perpendicular to the surface. The under-head ribs should facilitate countersinking. If the timber is very soft, the ribs may not fully embed. In some cases, a slight countersink might be necessary before driving.
