Pole barns are built primarily to be used as agricultural and storage buildings, although over the past ten years other types of buildings have been built using this type of construction.

These buildings are constructed using vertical wooden “poles” that are anchored in the ground.  Most of the time, wood framing is then fastened to these poles to provide the attachment points for metal roofing and metal siding.

The metal roofing and metal siding is fastened to the wood framing using what are called pole barn screws.  There are two types of pole barn screws:

Metal to wood pole barn screws fasten the metal roof panels and metal wall panels to the wood framing.  They have either hex washer heads with sealing washers or low profile torx heads with sealing washers and come in various sizes and lengths.  Pole barn metal to wood screws have either a self drilling or “sharp” point which drills or pierces the metal roof or metal wall panels before drilling into the wood framing.  Batt or foam board insulation is sometimes placed between the metal roof or metal wall panels and the wood framing before the pole barn screws are installed.

Metal to metal pole barn screws, also known as lap screws or stitch screws, are used in several places in pole barn buildings.  These screws have a self drilling or piercing point which penetrates two thicknesses of the metal where panels overlap (mostly on metal roofing) and also to attach metal trim pieces at doors, windows, corners, etc.

Pole barn screws are typically manufactured in lengths of 1”, 1-1/2”, 2”, 2 -1/2”, and 3”.

For fastening metal panels to wood framing, most metal roofing and metal siding manufacturers recommend using pole barn screws with shaft sizes #9 or #10, although #10, #12, and #14 (1/4”) are available.

Both carbon steel and stainless steel are used for pole barn screws – stainless steel is recommended for use with pressure treated (ACQ) lumber.

Pole barn screw heads are fabricated from either the same carbon steel or stainless steel material as the screw shaft, but also can be provided with ZAC (zinc aluminum) or stainless steel caps installed on carbon steel shafts.  ZAC or stainless caps on pole barn screws will prevent rusting of that portion of the screw that is visible after installation. 

Another important consideration for pole barn screws is the finish which is applied to the surface of the screw.  Most carbon steel pole barn screws are plated with zinc as part of the manufacturing process.  This prevents the carbon steel from rusting when exposed to the atmosphere.  Even if stored indoors, eventually the zinc coating will oxidize and eventually allow rust to form.  For carbon steel pole barn screws, where the head is exposed to the weather after they are installed, some additional coating is required.

The purpose of zinc aluminum cap (ZAC) and stainless steel caps on carbon steel screws  is to insure that, even if not painted, the portion of the pole barn screw that is exposed to the weather will not rust.

Most pole barn screws are painted to match the color of the metal roof panels or metal siding panels they attach. Pole barn screws are painted in one of two methods:  There are “post painter” facilities around the country which take unpainted pole barn screws and fasteners from domestic and international manufacturers and apply a single spray coating to the heads of these pole barn screws.   Imetal.net offers several different finishes under their matchColor program which are applied to pole barn screws at the manufacturer and consist of multiple pre-treating and finish coats in a controlled environment, guaranteeing superior longevity and more accurate color matching for pole barn screws than is provided by post-painting service providers.
