Lag Screw Hex Head Phillips Recessed Hardened Galvanizing Supplier

The lag screw also commonly known as the lag bolt, lag screws are some of the toughest fasteners. Lag bolts are used in wood construction for heavier load applications than most wood screws can support. These extremely sturdy fasteners are usually used to connect heavy lumber or other heavy materials that are bearing an intense load. Ever Hardware provides the custom made lag screw and customizable packaging.

These screws differ from normal wood, self-drilling, or sheet metal screws. Compared to most ordinary screws, lag screws are massive in size. Most lag screws are at least one inch long and inch thick.
For example, wood screws are used when connecting an application with only wood materials. These wood screws boast coarse threading, but that threading does not encompass the length of the screw. Normal wood screws thread as they enter the wood, where lag screws require a hole to be drilled first. Lag screws also use a nut to add extra strength and security to help hold things together. Used for intense load applications, lag screws can support a much heavier load than the average sheet metal or wood screw.
Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in three ways:
It forms a coating of zinc which, when intact, prevents corrosive substances from reaching the underlying steel or iron.
The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
The zinc protects its base metal by corroding before iron. For better results, the application of chromates over zinc is also seen as an industrial trend.
