A trade bulk tub of 275 high-performance 5.0 x 100mm woodscrews is a heavy-duty structural timber fixing package housed in a re-sealable, weather-resistant plastic tub. Featuring double-countersunk heads with self-sinking reaming ribs, deep partial threading, and sharp split-resistant slash points, these screws drive quickly without pre-drilling in softwoods. The 100mm length combined with a 5.0mm gauge delivers maximum holding power and pull-out strength, making this bulk format ideal for high-volume structural site framing, post anchoring, joist securing, and timber assembly.
