Identifying a fastener supplier through the product marking on the fastener is crucial. There are several important points to consider regarding these "identification marks."
Firstly, not all fasteners require an identification mark. According to GB/T3098 (ISO898, ISO3506, etc.), bolts, studs, hex nuts, and hexagonal (flower-shaped) cylindrical heads made of carbon steel, alloy steel, stainless steel, or non-ferrous metals must carry both the "performance level" and the "fastener manufacturer (or distributor) identification mark." This applies to screw products that adhere to the mechanical properties standards set out in these guidelines.
It’s important to distinguish between the identification mark and a trademark. The identification mark is part of product quality control and standardization efforts. It should be managed uniformly and approved by the national standardization body. The guidelines in Chapter 3 of GB/T90.2 "Fastener Marking and Packaging" specify that product markings must comply with national and industry standards. Specifically, the "manufacturer's identification mark" (or the distributor's mark) is distinct from a trademark and falls under product quality oversight.
In China, the coordination, confirmation, and announcement of identification marks have evolved over time. In 1987, ASME informed the former National Bureau of Standards that the U.S. Department of Defense required manufacturers to register their identification marks with ASME. This quality assurance mechanism prompted discussions in China about implementing similar practices. By October 1987, the first batch of confirmed fastener product marks was announced and communicated to ASME.
Further developments occurred in 1990 when the second batch of confirmed fastener product logos was released. In the 21st century, with changes in the machinery industry, the identification marks became more complex. The former State Bureau of Quality and Technical Supervision requested re-registration and confirmation of these marks. This led to the issuance of the "First Identification of Manufacturers' Identification Marks" in August 2000 and the "Second Batch of Confirmed Fastener Manufacturer Identification Marks" in May 2001.
As time passed, some certificates expired, companies reorganized, or were renamed, leading to an increasing number of identification marks. Coordination, confirmation, and release of these marks became a regular process. Initially, these were announced via paper releases, but this method proved inconvenient and prone to confusion. Starting in 2008, announcements shifted to electronic formats on relevant websites and professional journals. Despite this change, the Secretariat of the National Fastener Standardization Technical Committee decided in April 2012 to resume the "release announcement," ensuring clarity and completeness of the information.
Producing the identification mark on fasteners is not optional. It signifies that the product meets the standards and guarantees the quality. It also reflects the integrity of the company. Without this mark, products may be considered substandard. Each fastener sold should bear its own identification mark, indicating the company’s commitment to its product quality.
The "use certificate" has a limited validity period, making it essential for supervision by various parties, including quality and technology supervisory departments, businesses, and consumers. The National Fastener Standardization Technical Committee Secretariat encourages all stakeholders to monitor compliance. Their contact details are available for further inquiries.
