Use either zinc plated or stainless steel. Get philips head if you can as the PH2 but fits them very nicely, otherwise pozidrive will do.
Indicative Pricing With Allowance for P&P
You will always buy these in a pack rather than individually. Buying 10 or 20 is often virtually an identical price to buying 5. So, based on buying 20 the unit price is about £0.15
Pozidrive is an option if you can’t get phillips head.
