Can I use this screw instead?
You are one screw short and there is a jar of odds and ends on the bench. Check before you drive it in.
The screw you need
The screw you have
Only if the hole is open at the bottom
- 1.0 mm longer.
- A longer screw can bottom out in a blind hole and crack the boss, or poke through a board and short something.
Head shape and material matter too
Even with the right thread, a taller head can stop a cover closing, and a steel screw in an aluminium frame outdoors will corrode. Match the head shape the part came with.
