M16 x 200mm Hot Dip Galvanised Cup Head Bolts & Nuts

Secure thick timber connections with robust fasteners built for outdoor projects that demand lasting strength. These M16 x 200mm cup head bolts and nuts deliver reliable anchoring for posts, beams, and structural framing.

With a 16mm diameter and 200mm length, they provide the durability you need for decks, pergolas, and retaining walls in coastal or exposed environments. The hot-dip galvanised coating adds rust and corrosion resistance, helping structures stay solid year after year.

The smooth cup head sits flush for a clean, tamper-resistant finish, so outdoor installations look polished while staying securely fastened.
