Unlocking the Potential of JIS Fasteners: A Comprehensive Guide to Standards, Applications, and Global Trade


jis banner

    Fasteners are devices that mechanically join or attach two or more objects together. They are essential for various industries and applications, such as construction, automotive, aerospace, electronics, and medical. However, not all fasteners are the same. Different countries and regions have different standards such as DIN, ISO, ASME, ANSI and etc. As well as, specifications for fasteners, such as size, shape, material, and application. One of the most widely used and recognized standards for fasteners is the Japanese Industrial Standards (JIS).

What are JIS Fasteners?

    JIS fasteners are fasteners that conform to the JIS standards, which are established and maintained by the Japanese Standards Association (JSA) around 1945. JIS standards cover various aspects of fasteners, such as terminology, dimensions, tolerances, materials, surface treatments, testing methods, and quality control.  JIS standards aim to ensure the quality, safety, and reliability of fasteners, as well as to facilitate the trade and exchange of fasteners between Japan and other countries


    JIS fasteners include various types of fasteners, such as bolts, screws, nuts, washers, rivets, pins, clips, and staples. JIS fasteners are designated by a letter and a number, such as JIS B 1180. The letter indicates the field of application, such as A for civil engineering and architecture, B for mechanical engineering, or F for shipbuilding. 

The number indicates the specific standard within the field of application, such as JIS B1176 for Metric Socket Cap Screw.

Why are JIS Fasteners Important?

JIS fasteners are important for several reasons, such as:

  • JIS fasteners are compatible with many Japanese machines and products, which are widely used and exported around the world. For example, many machine tools, electric appliances, and vehicles made in Japan require JIS fasteners for their assembly and maintenance.
    • Using JIS fasteners can ensure the proper fit and function of these machines and products, as well as avoid any damage or malfunction caused by incompatible fasteners

  • JIS fasteners are reliable and durable, as they are made from high-quality materials and undergo strict quality control. JIS fasteners are designed to withstand various conditions and environments, such as pressure, temperature, corrosion, and vibration. JIS fasteners also have certificates and reports to prove their compliance with the JIS standards, such as RoHS, REACH, or MSDS. 
    • Using JIS fasteners can ensure the performance, safety, and reliability of the fastened systems

  • JIS fasteners are versatile and adaptable, as they are available in various sizes, shapes, and materials to suit different needs and preferences. JIS fasteners can also be customized or modified to meet specific requirements or challenges, such as slim head fasteners, washer-assembled screws, products assembled with spring washers, or hex socket screws. 

It is important to understand and gather as much information as possible about your customer’s applications and needs. This ensures the delivery of the correct fasteners, whether it matches to the standard or the specific type required.

    Some JIS fasteners are compatible with ISO and DIN fasteners when strict dimensional restrictions are not a concern. Finding the right fasteners for your application can be challenging, so considering an equivalent standard may be a viable option to ensure your installation runs smoothly and seamlessly.

How to Get JIS Fasteners?

    If you are looking for JIS fasteners for any types of assembly and applications, you will need a reliable and reputable source that can provide you with a wide range of JIS fasteners and fast delivery to your country.

            Of course, Most of fasteners company in Japan sell JIS fasteners but some of them are unable to ship to abroad due to several reason such as no experience in foreign trade in term of document and negotiation, no intention to sell to abroad, or even language barrier, and etc.
