1000SST Tek Screws
1000SST self-drilling screws. SST is the trade abbreviation for salt spray test, and this is the line to ask about when plain zinc will not survive the exposure but full stainless is more than the job needs. Tell us the salt spray figure you have to hit and we will confirm in writing what this item is finished to.

Questions we get asked about this item
What salt spray figure does this item reach?
We confirm the figure in writing against the finish you order rather than printing one number here, because it changes with the coating system. Dacromet, Ruspert and Xylan are the coatings that reach the upper end of the catalogue range.
How does salt spray relate to years on a building?
It does not convert directly — it is a comparative test, not a service life. Use it to rank finishes against each other, and tell us the actual exposure so we can advise.
