Understanding M20 20 Bolt Specifications and Applications

The M20 20 bolt is a specific type of bolt commonly used in various engineering and construction applications. Identified by its diameter and thread pitch, the M in M20 indicates that it is a metric bolt, while the 20 signifies that it has a nominal diameter of 20 mm. The size and design of these bolts make them integral to numerous structural and mechanical systems.

The M20 20 bolt typically features a thread pitch of 2.5 mm, which is standard for bolts of this size in the metric system. Besides its diameter, several factors such as length, material, grade, and coating significantly influence its performance and selection for specific applications.

Length M20 bolts are available in various lengths ranging from 30 mm to over 300 mm, allowing for flexibility depending on the requirements of the specific project.

Material These bolts are manufactured from a variety of materials, including carbon steel, stainless steel, and alloy steel. The choice of material impacts the bolt's tensile strength, corrosion resistance, and overall durability, making it crucial to select the right type for the environment in which the bolt will be used.

Grade Bolts are also classified by their grade, which denotes their strength and material properties. Common grades for M20 bolts include Grade 8.8, 10.9, and 12.9 in steel applications. Higher grades indicate a stronger bolt, which is necessary in heavy-duty applications where high tensile strength is essential.

Coating Additionally, M20 bolts can be treated with various coatings such as zinc plating, galvanizing, or other corrosion-resistant treatments. This is particularly important when the bolts are used in outdoor or aggressive environments, where moisture and atmospheric gases can lead to rust and degradation.
