Self-drilling screw for gate connectors and base plates
This self-drilling screw is used to fix gate connectors and to mount a post in its base plate. Each of these jobs takes two screws.
Sizes and fit
The screw measures 6.3 x 38 mm. Its own drill point lets it bore easily through a steel flange, so no pilot hole is needed.
Materials and finish
The screw is galvanized, giving the steel protection against corrosion outdoors, where fence hardware stays exposed to the weather all year round.
Installation
Drive the screw with a drill driver at the fixing point. Count two screws per gate connection and two per post in a base plate when you order, and keep a few spares on hand for site work. Hold the driver square to the steel surface so the drill point cuts cleanly and the screw seats flat against the fitting. Do not over-tighten.
