12x105

12x105 typically refers to a specific size designation used in various contexts, most commonly for fasteners or building materials. In the context of fasteners, such as screws or bolts, "12x105" indicates the diameter and length. The "12" usually represents the diameter in a specific unit system, often referring to a gauge size or a measurement in millimeters or inches depending on the standard. The "105" signifies the length of the fastener, typically measured in millimeters or inches.

In the realm of lumber or construction materials, "12x105" might denote the nominal dimensions of a piece of wood. The first number, "12", would represent the width or depth, and the second number, "105", would represent the length. These dimensions are often nominal, meaning they are the approximate size before finishing or milling. The actual dimensions might be slightly different. The unit of measurement for these lumber sizes is generally in inches, though metric equivalents are also used.

Without further context, the precise meaning of "12x105" remains ambiguous. It is essential to consider the surrounding information or the specific industry to accurately interpret this designation. For instance, if discussing hardware, it is a fastener size. If discussing construction, it is likely a lumber dimension. The standards governing these measurements vary by region and application.
