Coated Fasteners
What are fastener standards?
Fastener standards are technical specifications that set out requirements for the design, testing, and production of different types of fasteners. They are used to ensure that products are safe, reliable, and of consistent quality. The standards cover all aspects from the materials used to produce the fasteners, their shapes and sizes, as well as their intended applications. By adhering to these standards, manufacturers can ensure their products will meet the expectations of their customers. These standards help to ensure that all components made with fasteners adhere to certain guidelines so they can be properly and safely used in various applications.

What are SAE standards?
SAE (Society of Automotive Engineers) standards are a set of technical standards used to ensure consistent quality across automotive components, such as materials, designs, and processes. They are established and maintained by the SAE International organization, which works with the automotive industry to promote safety, sustainability, and technological innovation. These standards apply to a variety of areas including engines, chassis systems, powertrain components, fuels and lubricants. These standards cover a range of automotive engineering topics, including the performance, design, testing and manufacturing of vehicles, components and systems. SAE standards are recognized and used in the automotive industry worldwide.

What is ISO vs ASME Fasteners Standards?
ISO and ASME fasteners standards are two of the most widely recognized and respected industrial standards for bolts, nuts, and other threaded fasteners. The ISO standard, officially known as the International Organization for Standardization (ISO), is a global organization that develops standards across various industries.
The main difference between ISO and ASME fastener standards lies in their scope. While the ISO standard defines general fastener design requirements and testing methods for use worldwide, the ASME standard is limited to bolting applications specifically related to pressure vessel components. This means that ASME fastener standards are much more detailed than those established by ISO.

What is the difference between BS and BS EN Standards?
The main difference between BS and BS EN Standards is that BS (British Standards) is a British-based set of standards for products, services, and systems that are used in the UK, while BS EN Standards (European Norms) are European-based standards that are widely adopted across Europe. BS EN Standards cover many different aspects including quality, safety, environmental performance, design, materials and production methods. In addition to providing guidelines on how to meet specific product requirements, they also help to harmonize different countries’ requirements so they can be traded across the EU without difficulty.

What is the ASME standard for bolts and nuts?
The American Society of Mechanical Engineers (ASME) has developed standards for bolts and nuts under ASME B18.2.1, which covers the dimensional, chemical, and mechanical properties of various types of inch-series hex bolts, screws, and studs. This standard applies to both metric and U.S. customary units and outlines material specifications, torque values, head markings, and dimensions for different types of bolts and nuts. It covers diameters ranging from 1/4 inch through 4 inches, both coarse and fine thread varieties, strength grades A through DH and speciality fasteners such as Prevailing Torque Locking nuts.

What is the difference between SAE and ASTM Fasteners Standards?
The main difference between SAE and ASTM fastener standards is that the SAE standard is primarily used for the manufacture of bolts, nuts, screws, and washers made of alloy steel and carbon steel, while ASTM fastener standards are used for components manufactured from a variety of materials, such as stainless steel, nickel alloys, nonferrous alloys, plastics, and even concrete. Furthermore, SAE fasteners have tighter tolerances than ASTM ones. Additionally, ASTM has many different classifications of its standards depending on their application and type of material used to create the fastener while SAE only has two – grades 2 and 5.
