The annular nail has a high initial peak; however, the load generally decays quickly due to the annular rings "coring" the wood.
It was found that the stitched pattern resulted in 42 percent higher peak load capacity per fastener for 8d common nails, but for the helical and annular nails, peak load was similar to that achieved with a normal 90[degrees] drive angle.
However, the annular nails behaved differently in that there was generally a sudden decrease in a load just after the peak load was reached and an audible popping sound was noted.
The withdrawal energy increased for all nail types, with significant gains noted for the 8d common and annular nails.
Fix the hardboard (rough side up) with 19mm annular nails, ensuring that the heads don't stick up and, again, that you don't hammer through any cables or pipes underneath.
10 million different wires going to the and sky box, just required, cut along and clip over those stop the tangle spaghetti of Ring-Shank nails or Annular nails are used when the fixing is permanent and the nail needs to resist being pulled out.

Fix the hardboard (rough-side up) with 19mm annular nails, ensuring that the heads don't stick up and, again, that you don't hammer through any cables or pipes underneath.
The ringed shafts on the annular nails give you a much better grip and stop the floor creaking, and you don't want to use anything longer thanin in case you damage any pipes under the existing floor.
