3/8" X 5" 六角頭拉力螺絲 | 18/8 不鏽鋼 (200 顆 / 包)

Used these for a heavy timber deck repair and the 18/8 stainless held up perfectly in the damp weather. Each screw drove in cleanly without snapping, and the hex head gave my impact driver a solid bite.

Bought these for a timber frame project and honestly the 18/8 stainless is exactly what I needed since everything sits outside in the rain. The 3/8" width bites into the wood solidly without stripping, and having 200 in one box means I didn't have to make a second trip.

Was a bit worried about the threading at first, but once started they sink in cleanly and feel incredibly solid. The stainless steel finish is perfect for outdoor use without worrying about rust.
