One of the key features of this screw is its Type 17 cutting point tail, which allows for rapid chip removal when fastening wood materials, greatly improving work efficiency during installation. To enhance corrosion resistance, the threads are treated with Dacromet coating that can withstand 500 or even 1000 hours of salt spray testing, significantly extending the screw’s service life.
The screw head and the bonded washer are color-coated using a baking paint process, allowing the screw to match the color of the roofing or wall surface and providing a clean, aesthetically pleasing finish. The composite washer also provides excellent waterproof sealing.
These screws are widely used for fastening color steel plates to wood and are available in popular sizes such as 4.8mm, 5.5mm, and 6.3mm, with lengths ranging from 19mm to 100mm. We offer free samples for quality evaluation.
