EXCEPTIONAL SOLUTIONS FOR SPECIAL PROJECTS
Spax® Engineered Fasteners for Freshwater Dock and Marine Applications
There are different types of docks, including: floating docks, crib docks, pile docks, lift docks, and pipe docks. Each type may have advantages or disadvantages depending on setup and what you’re trying to achieve.
Similar materials are often used for dock tops that would be found in decking applications, for example they might be made of plastic, composite or PVC, treated lumber, or they may be made of an exotic hardwood. Also, much like decking, docks are structural and it’s critical that proper construction methods and techniques are used when building them to ensure not only longevity of the structure but also to maintain safety for users.
Docks can be a very large investment, and it’s something that’s visible and something that will often times get a lot of use, so building it right matters!
Things to Consider When Building a Dock
When it comes to many structural applications within dock building, SPAX® has an array of fasteners that are exterior HCR® coated, in order to provide longevity within the structure. Likewise on the dock top, SPAX has a wide array of fasteners to support your build, whether using a composite type board, treated lumber, or hardwood lumber. Additionally, SPAX offers a wide variety of screws in type 304 stainless steel in order to ensure long lasting connections.
Please note, in certain applications Stainless Steel fasteners should be used, and depending on building code, type 316 may be required.
SPAX® POWERLAGS® HIGH PERFORMANCE
SPAX offer the largest selection of code-recognized structural wood-to-wood fasteners in the industry.
AWPA Building Codes
Building code officials are required to have in-depth knowledge of all types of construction methods and thousands of different products used in modern buildings. The International Code Council’s committees recognize AWPA as the authority on treated wood and have directly referenced AWPA Standards in the International Building Code and International Residential Code in applications where preservative treated wood is required.
The Use Categories are a shorthand method of describing the various hazards to which wood products may be exposed. A brief description of the Use Categories is shown.
Information referenced from the AWPA site.

Exterior Treated Lumber Approved Fastener Coatings
HCR is a dual-barrier coating system designed to extend the longevity of SPAX® fasteners in ground-contact, treated lumber and exterior freshwater applications. Plated with a zinc base coat and finished with a durable top coat, they are engineered to withstand the toughest conditions.
HCR-X is a SPAX-developed, proprietary, dual- barrier coating system with superior corrosion protection against red rust, designed for use in both treated lumber and freshwater environments.
304 stainless steel fasteners provide code- compliant use in ground-contact, pressure-treated, and fire-retardant-treated lumber in general and coastal construction projects. They’re well-suited for use with cedar and redwood decking.
