If you want to understand about selecting hardware for your upcoming outdoor household furniture job, then you will want to study this article. Especially, I am going to be telling you about what variety of components will conduct very best, why the type of steel employed for fasteners and the complete used are significant concerns, and how appropriately preserving or limiting publicity of your home furnishings to soaked and winter season circumstances can boost existence span. Soon after you’re done with this article you will recognize that the very best decision of components for your outdoor furniture project is dependent on household furniture style, product used for design, picked location for the home furnishings and finances.

Picking out proper hardware for your home furnishings will assist make certain a lengthy existence span, as well as enhance the total appearance of your household furniture. Part of the problem is knowing what hardware to decide on when there are so a lot of solutions readily available at the components shop. The regular Lowes or Residence Depot carries a big choice of stainless metal, sizzling dipped galvanized, dazzling galvanized, simple steel, coated metal and brass bolts, nuts, washers and screws. Each style of fastener is suitable for sure applications, but not all are great for outside home furniture applications. 

In simple fact, picking the completely wrong fasteners can considerably shorten the lifespan of your household furniture, add to rot of wooden furnishings, cause unpleasant staining, and even make your home furniture unsafe to use. 

One particular factor that demands to be noted right up front is, do not ever use unprotected steel fasteners for out of doors home furniture, They will rust very immediately, and the steel will react with the tannic acid in the wooden creating streaks and staining. The tannic acid essentially speeds up the corrosion of the fasteners. Have you at any time observed a picket fence with black streaks operating down the boards from the nails? This fence was put in with the incorrect sort of fasteners. The same point will occur to your home furnishings. Even even worse, as the fasteners rust, they will velocity up the decay method of the wooden around the rusted fasteners, ruining your household furniture and creating it likely unsafe to use.

Hot Dipped Galvanized

Screws and bolts dealt with by incredibly hot dipped galvanizing are precisely developed for use outside. Electroplated galvanized or brilliant galvanized fasteners in the end will not keep up as effectively as the scorching dipped galvanized hardware. Zinc is made use of as a coating in both of those approaches, and functions as a barrier from the factors and the tannic acids in the wooden. 

I strongly recommend only making use of screws or bolts in the design of outdoor furnishings, even so. The galvanized finish on nails, possibly electroplated or scorching dipped, can quickly come to be destroyed when hammering them in, exposing the nail head to the things and letting them to commence rusting swiftly. 

Ample care need to be taken when installing galvanized screws. Drill pilot holes in hardwoods, and be guaranteed to use a bit that is not worn and inclined to skipping in the screw head. For whatever reason, the galvanized screws appear to not be as effectively tempered as other metal fasteners, and are far more probable to possibly snap off or have the heads strip out while putting in them. Due to the allowance necessary for the hot dipped coating, galvanized bolts do not have as tight of tolerance on the threads, and are much more possible to strip if more than tightened.

Warm dipped galvanized fasteners are a good preference for a lot of outside furniture purposes, like Adirondack Chairs, but are not the finest option for use in woods, these as teak.

Stainless steel

Stainless steel is the very best decision for use in woods with larger levels of tannic acid, such as teak. Stainless metal is an alloy or blend of steel, nickel and chrome. The ratio of the other metals with the steel figure out the weather conditions and corrosion resistance of stainless steel. Mainly because the steel is mixed with other softer metals, the stainless metal is not as robust, so predrilling of screw holes is really encouraged in all purposes, and essential in hardwoods this kind of as teak and mahogany. The extra corrosion resistance a lot more than outweighs any shortcomings that the metallic may possibly have, in particular in outside household furniture apps. 

While stainless metal fasteners are the most rust resistant, they are also the most costly of the choices we are talking about. Nonetheless, utilizing stainless steel fasteners will add several years of existence to your home furnishings. In the respect, they are an financial commitment that will spend out for yrs to come.


I have seen brass made use of in some commercially created outside furnishings, but do not advise it. Even though brass does not kind crimson rust, and is effectively suited for several damp apps this sort of as bogs and sinks, it does tarnish and corrode. It is also really susceptible to the tannic acids in wooden, which will induce it to are unsuccessful additional rapidly. Brass screws in certain do not have ample toughness for out of doors home furnishings purposes.

Outdoor or deck screws

In the earlier many yrs a quantity of brands have released outside fastening items exclusively marketed for deck developing. These will commonly be environmentally friendly, grey, tan or brown. These screws are both ceramic or plastic coated to hold off the metal reacting with the wooden acids. The specific coating methods are proprietary to every single 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 perform just great. Sad to say, I have not appear across bolts with this sort of complete. The brand name of screw I used was Deck Mate, and they have been out there in tan and brown, so that the colour can be chosen to far better match the wooden currently being utilised. These screws are ceramic coated, and the maker presented a coated bit for installation, which was made to not harm the ceramic coating at the screw head. If you opt for this form of fastener, be guaranteed to look at the expense with stainless steel, as the cost will change. If the stainless metal is fairly comparable in price, it would be the advised fastener. 

Constantly be certain to read through the makers technical specs on the box to be confident that the screws are acceptable for your application. 

Other Things to consider

If you are building home furnishings that will be positioned on a lined porch or patio exactly where it will be guarded from the things, the worry will be the conversation between the wood and the fasteners, a lot extra so than the temperature. Furnishings that will be uncovered to the factors all calendar year, such as a garden bench, or an Adirondack chair in the corner of your garden, will have to be made with substantially much more treatment and problem to guarantee that they hold up much more than just one or two winters.

Supplemental criteria should be created further than just the preference of what sort of fastener to use, even though this is extremely crucial. For illustration, fasteners should not be found where h2o the place obtain and sit on the fasteners for an extended interval of time. The screws that connect the seat slats to an Adirondack chair are a prime instance- typically these screws will be countersunk down below the area of the wooden. This will let drinking water to acquire in the screw holes, shortening the life span of all but stainless steel fasteners, and prolonging the publicity of the wooden to h2o, which will improve the rate of decay. In applications in which the furnishings will be uncovered to the aspects calendar year round the screw heads must be pushed flush with the area of the encompassing wood. 

Design and style and design of the home furniture are also important factors. Are the horizontal surfaces of the home furnishings manufactured in these types of a way that will allow for them to drop h2o, instead than accumulate it? Think of a picnic desk with a slatted or board major. The gaps in between the boards make it possible for water a way to operate off the best and not pool up. 


Stainless steel is commonly the finest option for outside home furniture applications, even though the expense may be prohibitive for some. There are other less high-priced fastener solutions accessible that will perform acceptably. Do not use unprotected steel fasteners for outside furnishings applications underneath any instances. Know exactly where and how you intend to use your furniture and style and design it for the conditions it will be subjected to.
