Questions we get asked about this item
Is 3000 hours salt spray the figure for every screw you make?
No. 3000 hours is the maximum reached on this stainless self-drilling line. Across the catalogue the salt spray test range is 24 to 2000 hours depending on material and finish, and we state the figure that applies to the item you are quoting.
Which grade goes into a marine fixing?
For salt-laden air ask for 316. Tell us the exposure and we will confirm grade and finish together rather than quoting one without the other.
