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.

At its core, the foundation bolt is responsible for several key functions within the firing mechanism. Primarily, it houses the firing pin, which strikes the primer of the cartridge to initiate the firing sequence. Additionally, the bolt itself locks into the chamber when the rifle is fired, containing the pressure created by the igniting gunpowder. This locking mechanism is crucial for the safe and effective operation of the firearm, allowing for the rapid cycling of cartridges and maintaining accuracy during high rates of fire.

The Role of Washers

2. Vibration Absorption In mechanical applications, machines and equipment often experience vibrations during operation. Rubber washers act as shock absorbers, reducing the impact of these vibrations on the screw and the surrounding materials. This can prolong the life of both the fastener and the assembly it secures.

Additionally, chemical anchors offer versatility in installation. They can be used in a wide range of conditions, including cracked concrete and environments with variable temperatures. Furthermore, they significantly reduce the risk of spalling concrete, which can occur with mechanical expansion anchors, thereby preserving the integrity of the substrate.
