Specifications

Which one do I need?

Size 6.3 x 45mm gives you the diameter first and the length second. Allow for the sheet, any packing under it and the depth you want in the support, and compare the total with 45mm.

How to use

1. Check the sheet and the support below are the right way round and lined up before you start.
2. Fit a hex socket that matches the head and keep it square to the screw.
3. Drive until the washer sits snug against the sheet without crushing it.
4. Wear eye protection and gloves, because self drilling screws throw swarf.
