- Larger bearing area for gripping
- Referred to as both bolts and screws
- Partially threaded with a shoulder beneath the head
- Extremely corrosion resistant
- Used in long lasting and outdoor applications
- Due to the finishing process for Hot Dip Galvanized fasteners, it is recommended to only use Hot Dip Galvanized fasteners with Hot Dip Galvanized fasteners and not mix metals. This can create threading and durability issues.
