The WKT construction screw is designed for installing over-rafter insulation on timber structures. Its double-thread design provides secure fastening without excessively compressing the insulation material: the longer thread anchors into the rafter, while the shorter thread beneath the head securely fixes the counter batten. The wide wafer head increases the bearing surface and improves joint strength. The self-drilling tip allows easy installation without pre-drilling, while the high pull-out resistance makes the screw suitable for other load-bearing timber structures.
