M20 Anchor Bolts Specifications and Factory Manufacturing Details for Construction Applications

Understanding M20 Anchor Bolts Dimensions and Factories

When it comes to construction and heavy infrastructure projects, the choice of fasteners is crucial. Among these, anchor bolts play a vital role in securing structures to their foundations. One of the most commonly used anchor bolts is the M20 anchor bolt, known for its reliability and versatility. This article delves into the dimensions of M20 anchor bolts and insights into the factories that manufacture them.

What are M20 Anchor Bolts?

M20 anchor bolts are a type of fastener made from high-strength steel, designed to anchor structures to concrete or masonry. The M in M20 denotes the metric thread, while 20 indicates the nominal diameter of the bolt in millimeters, which is 20mm. These bolts come in various grades, typically ranging from 4.6 to 10.9, where a higher grade signifies greater tensile strength.

Dimensions of M20 Anchor Bolts

The standard dimensions of an M20 anchor bolt are critical for ensuring compatibility with various construction applications. Generally, the specifications include the following

- Nominal Diameter 20mm - Length Depending on the application, M20 anchor bolts can range from 100mm to 1000mm in length or more, with common lengths being 200mm, 400mm, and 600mm. - Thread Pitch The standard thread pitch for an M20 bolt is 2.5mm, which is suitable for a wide array of fastening needs. - Head Type M20 anchor bolts can come with various head types, including hex head, round head, or square head, each chosen based on the tools available and specific requirements of the project. - Coating Many manufacturers apply protective coatings, such as zinc plating or hot-dip galvanizing, to prevent corrosion, especially when used in outdoor or high-humidity environments.

Manufacturers often adhere to international standards such as ASTM, ISO, or DIN to ensure the quality and durability of the bolts produced.

The manufacturing of M20 anchor bolts is a specialized process that requires advanced machinery and expertise. Global factories producing these fasteners are often equipped with cutting-edge technology to ensure precision in dimension and strength. Key regions known for anchor bolt manufacturing include

- China As a leading producer of construction fasteners, several factories in China specialize in the production of M20 anchor bolts. These factories leverage affordable labor and advanced manufacturing techniques to keep costs competitive. - Germany Renowned for its engineering excellence, Germany produces high-quality M20 anchor bolts that meet stringent quality standards. Factories here focus on durable materials and innovative designs, often catering to the European market.
