TIMco Hex Flange Advanced Coach Screws - 6.0 x 50mm - Yellow - Pack of 12

The main advantage is the significantly faster installation time, up to 3x faster, due to the hex flange head compatible with power tools and the aggressive slash point tip.

Yes, the yellow zinc plating with passivation provides enhanced corrosion resistance, making them suitable for many outdoor applications. However, for extremely harsh or coastal environments, stainless steel alternatives might offer superior longevity.

The aggressive slash point tip is designed to reduce timber splitting and often eliminates the need for pre-drilling in softwoods and engineered boards. However, for hardwoods, very close to edges, or in masonry, pre-drilling is recommended.

You will need a drill bit that matches the diameter of the nylon plug you are using. Refer to the plug manufacturer's recommendations for the correct drill bit size.

Each pack contains 12 screws.

You will need a hex socket or a driver bit that matches the size of the hex flange head, typically used with a power drill or impact driver.

Ensure you are using the correct size hex driver bit and that it is fully seated in the screw head. Reduce the torque setting on your power tool and try again. For very hard materials, consider pre-drilling a pilot hole.

The aggressive slash point tip is designed to minimize splitting. If splitting occurs, it may be due to very brittle timber or driving too close to the edge. Ensure adequate edge distance or consider a slightly larger pilot hole.

Confirm that a suitable nylon plug is being used and that the pilot hole drilled for the plug is the correct size. Ensure the plug is fully seated before inserting the screw. The screw is designed for lighter duty masonry applications when used with plugs.

While designed for corrosion resistance, prolonged exposure to moisture or corrosive environments can affect the finish. Ensure storage in a dry place and clean off any contaminants. For highly corrosive environments, specialized stainless steel fixings may be required.
