ISI Certification (BIS) for
Fasteners Drilling Screws with Tapping Screw Thread Part 1 Pan Head IS 18471

Cross-recessed drilling screws with tapping screw threads play a very important role in various industries. These fasteners are designed to create secure connections in various materials like wood, metal, and plastic. To ensure that these products meet quality standards, regulatory bodies like the Bureau of Indian Standards (BIS) provide certification.

These screws follow standardized specifications such as IS 18471 to ensure they meet high performance and reliability requirements. Let’s delve deeper to know more about BIS certification of Cross Recessed Drilling Screws. 

Cross Recessed Drilling Screws IS 18471 Specification: An Overview

IS 18471 (Part 1) aligns with the international standard IS 15481, which allows for consistency in quality and specifications for cross-recessed pan head drilling screws on a global spectrum.

• Primary Conditions of Standard: This standard provides characteristics of the screw thread for cross-recessed pan head drilling screws sized from ST2.9 to ST6.3. 
• Dimensions & tolerances: The standard provides dimensions for various components of the screw and head diameter, including the thread and length. 
• Steel Material Specification: The screws produced are made from steel material of the types specified as well as mechanical and functional performance.
• Surface Finish: There are specifications for both plain and electroplated finishes, with the specifications for electroplating referenced. 
• Cross Recesses: The cross recesses on the screw heads are important for aligning and engaging the relevant screwdrivers or bits and are important for driving the screws safely and effectively.
• Mechanical Properties: The screws must meet certain mechanical properties (e.g., hardness, tensile strength) to ensure that the screws are functional and effective for specific applications.
• Tolerances: Tolerances for dimensions and mechanical properties must also be specified to ensure that screws will be manufactured within specified tolerances, which are referenced.

IS 18471 Quality Control Order

The DPIIT, Ministry of Commerce & Industry, Government of India, has put out a draft Quality Control Order that would make it mandatory for the Standard Mark of the Bureau of Indian Standards under a valid BIS license to be affixed to all cross-recessed screws referred to above, whether indigenously manufactured or imported from a foreign country, to be used in India.

The cross-recessed screws must bear the BIS standard mark and comply with relevant standards for sale in India. BIS has not officially published the standard, but it will be published soon on the official website.
