  • Plate, Hexagonal Nuts

  • Extensive testing and field use have proven Weatherguard is far superior in corrosion resistance over competitive standard zinc-plated products.


    Without weatherguard technology products are exposed to harsh weather conditions


    Rust resistant technology keeps your gate hardware and outdoor hardware stronger longer


    Superior coating against the elements keeps National Hardware products protected

    Tested against the competition

    Weatherguard coating protects against rust

    When subjected to 312 hours of salt fog spray testing (BHMA A156.18)- 2016, standard zinc hardware showed severe corrosion while hardware protected by Weatherguard withstood these harsh conditions with very little deterioration.

    Protects against rain damage

    With a rust resistant coating, products last longer in harsh conditions. Look for the Weatherguard shield on National Hardware products.

    Keeps your National Hardware products safe in coastal areas

    Weatherguard helps protect against salt corrosion on zinc plated products.

    Weatherguard extends the life of products in harsh winter conditions

    Snow can be hard on outdoor products. Weatherguard's clear coat helps keep products like outdoor hinges safe through the winter.

    Benefits

    Protects against humidity

    Safe to use with pressure treated lumber

    Superior rust protection

    Extends the life of outdoor hardware

    They appear to be nice and well built. Threads are clean. Biggest issue we’ve run into is that the measurement they provide has a mixed base - width stated uses inner diameter while the height uses outer diameter. Fits the width perfectly but coming up half inch short... See more
    They appear to be nice and well built. Threads are clean. Biggest issue we’ve run into is that the measurement they provide has a mixed base - width stated uses inner diameter while the height uses outer diameter. Fits the width perfectly but coming up half inch short because they included the thickness of the bolt in the height.
    One of the images show it to be 7.3” OD but it is more like 7.003”

    Ordered 4 u-bolts, and for bolts... they''re just fine. But one of the u-bolts was missing one of two nuts... Lucky me I happen to have a spare that was exactly the same size. Come on Amazon, no quick check before throwing stuff in a box and sending it off? Does it look right? Do they all match? Pretty annoying to have to source a spare nut when there are only so many parts that had to make it into the box. Thus the 3 star review.

    I used these for my after market exhaust on my truck. The tail pipe was clanking on my bumper so I wanted to tighten it up a bit. It''s all fixed. For this I recommend some Teflon tape or the bolts will loosen.
