Stainless steel hex bolt. A4 Marine (316) Grade. General use with a huge number of applications typically including architecture, equipment, commercial and domestic construction. Stainless Steel coach screws are strong, look good with a clean finish and are resistant to corrosion.
Unfortunately sent the wrong size bolt, when I emailed there was no response and when I called I was informed I was told it would be resent but not received after 2wks.
