What is BS EN ISO 4017:2012

BS EN ISO 4017:2012 is a technical standard that specifies the characteristics of hexagon head bolts with threads from M1,6 up to including M64, of product grade A for threads M1,6 to M24 and property classes 8.8, 9.8, 10.9 and A2-70 for threads larger than M24. This article aims to provide an easy-to-understand explanation of this technical standard, highlighting its importance and applications.

Understanding the Standard

The BS EN ISO 4017:2012 standard defines the requirements for hexagon head bolts, also known as cap screws. These bolts have a threaded shank and six-sided head, which makes them suitable for various fastening applications. The standard covers bolts with sizes ranging from M1.6 to M64, providing a comprehensive range of options for different needs.

The standard also specifies the product grades and property classes of these bolts. Product grade A is applicable for bolts with thread sizes from M1.6 to M24, while property classes 8.8, 9.8, 10.9, and A2-70 are used for bolts with thread sizes larger than M24. These classifications ensure that the bolts meet specific strength and durability requirements, making them reliable choices for engineering and construction purposes.

Importance in Industry

BS EN ISO 4017:2012 plays a crucial role in the manufacturing and construction industries. The standard ensures that hexagon head bolts produced by different manufacturers meet consistent quality and performance standards. This uniformity allows engineers and builders to confidently select and use these bolts in their projects, ensuring safety and reliability.

Compliance with this standard also simplifies the procurement process, as it facilitates accurate specification and identification of hexagon head bolts. Manufacturers, suppliers, and end-users can easily communicate their requirements using the designated product grades and property classes defined in BS EN ISO 4017:2012.

Applications and Usage

The applications of bolts conforming to BS EN ISO 4017:2012 are numerous and varied. These bolts are commonly used in construction, machinery, automotive, and aerospace industries, among others. They can provide secure fastening for structural components, such as steel beams and machinery parts, ensuring stability and integrity.

The standardized threading and design of these bolts allow for easy and efficient installation, reducing labor time and costs. The wide range of available sizes and strength classifications provides flexibility for different project requirements, offering suitable solutions for both heavy-duty applications and light-duty tasks.

In conclusion, BS EN ISO 4017:2012 is a technical standard that defines the characteristics and requirements for hexagon head bolts. Its importance lies in ensuring consistent quality, facilitating procurement, and enabling safe and reliable usage of these important fasteners in various industries and applications.
