Material selection, installation and ordering guidance for your coastal wood project.
Which stainless grade is supplied?+
Confirm the alloy with VERTEXA when requesting your quote. The supplied MultiGrip dimensions do not identify a stainless grade, so this page does not assign 304 or 316.
How should I choose stainless steel for a coastal site?+
Salt exposure varies by location, wind and maintenance. Match the stainless grade to the project specification. For direct salt spray, splash zones or immersion, request a corrosion-resistant material recommendation before ordering.
Should I pre-drill?+
Confirm the pilot-hole requirement for the wood species, board thickness and edge distance. Pre-drill where required, particularly in dense wood or near an edge. Use the matching Torx bit and stop when the head seats.
Can I use these for structural connections?+
This page provides woodwork applications and dimensions, not structural design values. Use an engineered fastening schedule and a fastener approved for that connection where required.
How do I request a price?+
Choose the size and quantity above, then select Request a quote. Tell us the wood type, delivery location and coastal exposure so we can confirm material, packaging and pricing.
