ISI Certification (BIS) for
Fasteners – Cross Recessed Drilling Screws with Tapping Screw Thread Part 2 Countersunk Head IS 18471 Part-2

BIS certification of Cross Recessed Drilling Screws with Tapping Screw Thread (Part 2: Countersunk Head) as per IS 18471 (Part 2) is mandatory as it provides quality and performance standards to customers. This Indian Standard (IS) ensures that products meet reliability, durability, and safety standards. Cross-recessed drilling screws are valuable in furthering the tasks. To ensure the structural integrity and ease of use. Let’s delve deeper to know more about the Bureau of Indian Standards scheme and the role of ERCS in the certification of the product.

Tapping Screw Thread Part 2 Countersunk Head IS 18471 Part-2 Specification: An Overview

The key specifications of countersunk head cross-recessed drilling screws with tapping screw thread IS 18471 Part 2 are as follows:

• The drilling point of the screw is designed to create a hole as it is driven into the material, eliminating the need for a pre-drilled hole. 
• The screw features a specialized tapping thread that enables it to form threads in materials such as plastic, wood, or thin metal, driven in to create a thin and secure fit. 
• Screws are made up of high-quality carbon steel, stainless steel, or other materials that provide durability and resistance to corrosion. 
• The standard includes guidelines for coating, such as zinc plating. It includes other finishes that increase corrosion resistance for industrial or outdoor environments. 
• The standard provides complete information regarding the size, thread specification, and length of the screw. These dimensions are crucial for compatibility with materials and tools. This includes head diameter, shank length, and thread pitch. 
• Screws feature a tapping thread profile; this includes a sharp edge to ensure clean and precise cutting threads in materials. The geometry is designed to be robust and durable, providing long-term reliability in applications that require assembly and disassembly.  
• The screws are tested to ensure that they meet the certain strength and tensile requirements. The standard ensures that the screw will not fail under normal use conditions, providing reliability and safety while using. 
• Manufacturers have to follow the exact tolerances and processes specified under IS 18471 (Part 2), which include heat treatment, coating, and threading processes.
• Screws undergo many tests, like thread engagement, pull-out strength, and corrosion resistance.
