Determining the Best Type of Fastener to Use For Outdoor Furniture Construction

If you want to study about picking out hardware for your future out of doors furniture challenge, then you will want to browse this article. Specifically, I will be telling you about what kind of components will execute best, why the kind of metal made use of for fasteners and the finish applied are important factors, and how correctly safeguarding or restricting exposure of your furnishings to soaked and wintertime situations can raise daily life span. Immediately after you happen to be completed with this posting you will recognize that the ideal alternative of components for your out of doors furnishings project is dependent on home furniture model, material utilised for design, selected locale for the home furniture and spending budget.

Choosing good components for your home furnishings will help ensure a extensive lifetime span, as properly as increase the all round look of your furniture. Part of the challenge is understanding what components to pick when there are so many alternatives accessible at the hardware retailer. The regular Lowes or Home Depot carries a enormous choice of stainless metal, very hot dipped galvanized, vibrant galvanized, basic metal, coated metal and brass bolts, nuts, washers and screws. Each sort of fastener is suited for specific programs, but not all are great for outside furniture programs. 

In point, picking the mistaken fasteners can greatly shorten the lifespan of your furnishings, add to rot of wooden household furniture, induce ugly staining, and even make your home furnishings unsafe to use. 

A single matter that demands to be famous proper up entrance is, do not at any time use unprotected steel fasteners for outdoor furniture, They will rust pretty promptly, and the steel will react with the tannic acid in the wood resulting in streaks and staining. The tannic acid really speeds up the corrosion of the fasteners. Have you at any time found a wood fence with black streaks working down the boards from the nails? This fence was set up with the incorrect variety of fasteners. The very same thing will take place to your furnishings. Even worse, as the fasteners rust, they will velocity up the decay procedure of the wood close to the rusted fasteners, ruining your home furnishings and earning it most likely unsafe to use.

Warm Dipped Galvanized

Screws and bolts taken care of by incredibly hot dipped galvanizing are particularly created for use outside. Electroplated galvanized or dazzling galvanized fasteners finally will not hold up as nicely as the very hot dipped galvanized hardware. Zinc is applied as a coating in the two solutions, and acts as a barrier from the elements and the tannic acids in the wooden. 

I strongly advise only utilizing screws or bolts in the construction of out of doors furnishings, having said that. The galvanized finish on nails, possibly electroplated or scorching dipped, can easily develop into damaged though hammering them in, exposing the nail head to the elements and allowing for them to start rusting speedily. 

Satisfactory care have to be taken when putting in galvanized screws. Drill pilot holes in hardwoods, and be positive to use a bit that is not worn and inclined to skipping in the screw head. For what ever cause, the galvanized screws appear to be to not be as effectively tempered as other steel fasteners, and are additional most likely to both snap off or have the heads strip out though putting in them. Because of to the allowance needed for the sizzling dipped coating, galvanized bolts do not have as tight of tolerance on the threads, and are extra probable to strip if more than tightened.

Very hot dipped galvanized fasteners are a high-quality option for quite a few out of doors home furniture programs, including Adirondack Chairs, but are not the ideal preference for use in woods, these as teak.

Stainless steel

Stainless metal is the ideal option for use in woods with larger ranges of tannic acid, these as teak. Stainless metal is an alloy or mix of steel, nickel and chrome. The ratio of the other metals with the steel ascertain the weather conditions and corrosion resistance of stainless metal. For the reason that the steel is blended with other softer metals, the stainless metal is not as solid, so predrilling of screw holes is highly advised in all apps, and crucial in hardwoods this kind of as teak and mahogany. The additional corrosion resistance extra than outweighs any shortcomings that the steel could have, specially in outside furniture apps. 

Although stainless metal fasteners are the most rust resistant, they are also the most highly-priced of the solutions we are speaking about. Even so, working with stainless metal fasteners will insert decades of daily life to your furnishings. In the regard, they are an expenditure that will spend out for a long time to arrive.


I have seen brass utilised in some commercially manufactured outside furniture, but do not recommend it. Though brass does not variety purple rust, and is nicely suited for a lot of wet programs this kind of as bathrooms and sinks, it does tarnish and corrode. It is also very susceptible to the tannic acids in wooden, which will induce it to are unsuccessful much more speedily. Brass screws in certain do not have adequate strength for out of doors home furnishings apps.

Out of doors or deck screws

In the past several decades a selection of brands have launched out of doors fastening products and solutions especially promoted for deck constructing. These will commonly be eco-friendly, grey, tan or brown. These screws are either ceramic or plastic coated to hold off the steel reacting with the wood acids. The distinct coating methods are proprietary to each producer, and can be a mixture of electroplated galvanizing and plastic, or a baked on ceramic.

I have utilised these fasteners in home furnishings apps and they conduct just wonderful. However, I have not arrive across bolts with this style of end. The brand name of screw I applied was Deck Mate, and they had been available in tan and brown, so that the shade can be selected to greater match the wood remaining utilized. These screws are ceramic coated, and the maker furnished a coated bit for installation, which was developed to not problems the ceramic coating at the screw head. If you pick out this kind of fastener, be absolutely sure to evaluate the charge with stainless steel, as the price will fluctuate. If the stainless steel is moderately comparable in expense, it would be the suggested fastener. 

Normally be absolutely sure to read through the makers specifications on the box to be absolutely sure that the screws are suitable for your application. 

Other Concerns

If you are creating furnishings that will be positioned on a covered porch or patio where it will be protected from the factors, the problem will be the conversation in between the wooden and the fasteners, significantly far more so than the climate. Household furniture that will be uncovered to the things all calendar year, this sort of as a back garden bench, or an Adirondack chair in the corner of your backyard, will have to be created with substantially more care and problem to make sure that they keep up a lot more than just one particular or two winters.

Additional criteria will have to be designed further than just the choice of what form of fastener to use, even though this is extremely crucial. For illustration, fasteners should really not be found exactly where water the place obtain and sit on the fasteners for an extended time period of time. The screws that attach the seat slats to an Adirondack chair are a key illustration- typically these screws will be countersunk underneath the area of the wood. This will allow for water to gather in the screw holes, shortening the lifestyle span of all but stainless metal fasteners, and prolonging the exposure of the wood to h2o, which will increase the rate of decay. In apps wherever the home furniture will be exposed to the components year spherical the screw heads should be driven flush with the surface of the encompassing wood. 

Building and design of the household furniture are also important criteria. Are the horizontal surfaces of the home furnishings produced in these a way that will permit them to get rid of h2o, relatively than obtain it? Think of a picnic table with a slatted or board major. The gaps between the boards allow water a way to run off the major and not pool up. 


Stainless metal is ordinarily the best decision for out of doors furniture purposes, though the charge might be prohibitive for some. There are other much less high priced fastener options obtainable that will conduct acceptably. Do not use unprotected metal fasteners for outdoor furnishings applications less than any circumstances. Know wherever and how you intend to use your household furniture and layout it for the problems it will be subjected to.
