Concrete is designed to be hard to punch through. What does one do, then, if one wishes to attach things to a concrete wall? Standard nails will bend as they cannot make it through. The solution is to use masonry nails--extremely tough nails explicitly used to fasten things to concrete. They are used to fix wooden strips to walls, attach shelf brackets, and even secure appliances and furniture to concrete floors. This guide is written to help select the most appropriate kind of masonry nail for one's needs.
Type of nail
There are two main types of nails in use--fluted masonry nails and cut masonry nails. The fluted style, created by cutting hardened steel wire and shaping the result, most commonly features a flat head and a sharp diamond tip perfect for driving through rigid materials. They can be fluted straight or twilled, where the fluting wraps around the shank at an angle. These ridges provide greater holding power and resist withdrawal by gripping the masonry's uneven surfaces.
On the other hand, cut masonry nails are wrought out of hardened steel and tend to be much larger than their wire counterparts. They have a unique shape, with a blunt end and a tapered shank, which helps resist bending and makes them extremely durable. Using them may be more appropriate in projects with a rustic or historical bent, as they can even penetrate stone surfaces and reinforced concrete.
Materials and finishing
As fluted masonry nails have to be extremely tough to punch through concrete, they are usually made of tempered high-carbon steel, which doesn't bend or give way easily. The nail surface may be plated with a zinc coating, which prevents them from corroding. Nails range from under an inch to up to 10" in length, with the longer nails suitable for driving thick pieces of wood into concrete floors.
Cut masonry nails, however, are made out of hardened steel. This lets them pierce surfaces even with a blunt end (though the worker should take care to wear goggles while applying them). They are also heat-treated to increase their resistance to bending. They may be hot-dipped galvanized for increased durability and corrosion protection, but using them probably isn't a good idea in applications where surface rust is unacceptable.
