Frequently Asked Questions (FAQ):

Q: What washers and nuts should I use?
A: Use Grade 2 washers and nuts with a zinc-plated finish to match strength and corrosion resistance.


Q: Can these be used outdoors?
A: The zinc plating offers basic corrosion resistance for typical outdoor use, but for harsh or marine environments consider a higher corrosion-resistant material like stainless steel or hot-dip galvanized.
