Introducing the Simpson Strong-Tie No. 8 x 2-1/2 in. Square Bugle Head Deck Screws — a rugged, outdoor-ready fastener set designed to deliver dependable performance on every deck project. Packed in a 22 lb bucket with 2,000 screws, this bulk selection keeps your job site moving without constant reordering.
Why these screws stand out
-
Durable materials and finish: Crafted from 305-grade stainless steel and finished with a protective coating, these screws resist corrosion in outdoor environments, helping your deck stand up to sun, rain, and humidity.
-
Square-drive simplicity: The square drive reduces cam-out for precise, flush seating, even after long days on the ladder. The included driver bit means you have what you need right away.
-
Correct size and threading: No. 8 diameter with a 2-1/2" length and coarse threads provides solid holding power for typical decking applications while minimizing splitting in softer boards.
-
Bugle head design: The bugle head seats neatly in the surface of the deck board, creating a clean, professional finish with fewer mushrooming impressions.
-
Uncollated, bulk practicality: Non-collated screws in a durable bucket streamline large installations, helping crews keep moving on multi-board decks.
