Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.

Lag screws, typically used for heavy-duty applications like securing wooden beams or attaching metal to wood, have traditionally required a separate drilling step before the screwing process. However, with the advent of self-drilling versions, this dual-step process is consolidated into one swift action. The self-drilling tip, often featuring a sharp point and flutes, cuts through material effortlessly, whether it's wood, metal, or even concrete, making them highly versatile.
