The M16 designation refers to the diameter of the bolt shank, which is 16 millimeters. This size makes the M16 anchor bolt an ideal choice for medium to heavy loads, commonly found in construction projects such as installations of steel beams, heavy machinery, or outdoor structures. M16 chemical anchors typically have a minimum tensile strength exceeding 20 kN, making them robust enough for demanding applications.

1. Time Efficiency Since there is no need for pre-drilling, installation time is significantly reduced. This can lead to lower labor costs and faster project completion.

Black phosphate drywall screws are versatile and can be used in various applications beyond just drywall installation. They are increasingly popular in the construction of ceilings, partitions, and other wall systems. Additionally, they can be used with multiple materials, including wood and metal studs, making them an all-around tool for various projects.

Furthermore, the hex head design improves grip when using power tools, providing a more secure connection than traditional slotted or Phillips heads. This feature leads to better torque application, which is crucial when working with harder materials. The increased grip also minimizes the likelihood of stripping the screw head during installation.
