IS 18471 : Part 1 : 2023/ISO 15481 : 1999 Fasteners - Cross Recessed Drilling Screws with Tapping Screw Thread - Part 1 Pan Head
New Standard from Last Update.
NATIONAL FOREWORD
This Indian Standard (Part 1) which is identical to ISO 15481 : 1999 'Cross recessed pan head drilling screws with tapping screw thread' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the General Engineering and Fasteners Sectional Committee and approval of the Production and General Engineering Division Council.
Drilling screws play a pivotal role in seamlessly joining materials and structures. These versatile screws feature sharp points and finely crafted threads that enable them to effortlessly penetrate a variety of substrates, creating secure and reliable connections. Drilling screws are engineered to provide efficiency and convenience by eliminating the need for pre-drilled holes or separate tapping processes. Their ability to create threads as they are driven into materials like metal, wood, or plastic translates into time and cost savings across industries ranging from construction, where they secure metal roofing and wall panels, to manufacturing, where they streamline assembly lines and attach components. Cross recessed drilling screws feature a unique cross-shaped indentation on their head, which corresponds to a specialized screwdriver or bit. This design allows for easy and secure driving of the screw into the material.
This standard is published in 3 parts. Other parts in this series are:
Part 2 Countersunk head
Part 3 Raised countersunk head
