Use and selection
This roofing type is identified by its #3 Phillips drive and reduced drill tip. The catalogue names black epoxy e-coating and a 14-TPI reference; confirm the thread pitch for the exact diameter and length requested. The table separates the #12, #14 and #15 nominal diameter references from their length ranges; select a specific configuration for review with the complete roof connection, including the supporting material and fixing detail.
