TurboGold PZ Double Self-Countersunk Woodscrews Expert Trade Case 2800 Pcs (39041)

Hello Miketheman69, These are not supplied with a screwdriver bit. They would need to be used with PZ2 and PZ3 sized bits. Thank you for using Q&A

Hello Netflix, Yes, you could use these screws with wall plugs. Thank you for using Q&A

Hello, These are carbon steel screws, so can cause galvanic corrosion when used on aluminium (this will only happen if there is moisture present though). Ideally you want to aim for a coated or plated screw as the coating will protect against rust and keep the screw material separated from the aluminium. Alternatively you can seal the screw/screw area with a sealer/paint, so that water cant get to the metals and cause the reaction in the first place. As you're attaching a sheet metal to wood you may also want to consider a more suitable type of screw. For example, EASYDRIVE ROOFING SCREWS 6.3 X 25MM 100 PACK (9353P). I hope this helps. Thanks for using Q&A. [DG]

Hello 5ilver5urfer, These are not intended as outdoor screws and, as such, do not have the necessary corrosion resistance for long-term exposure. We would instead recommend looking at item 9824X. Thank you for using Q&A AS

Hello B4dg3rm4n, We do not stock the inserts as a separate item unfortunately. Thank you for using Q&A SW
