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.

Fine thread drywall screws are designed primarily for securing drywall to wooden or metal studs. Their distinctive feature is the closely spaced threads, which provide greater holding power and reduce the chances of stripping compared to coarse thread screws. These screws are typically made from hardened steel, which enhances their strength and durability, making them suitable for a variety of applications beyond just drywall installation.
