S-92470A353 Length 16 mm DIN 7981 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Excellent holding power in sheet metal up to 0.025" thickness, thanks to the coarse thread and fully threaded design.
• Quick and secure installation with the Phillips No. 1 drive, reducing tool slippage and assembly time.
• Optimized for thread forming in sheet metal, creating strong, permanent threads without pre-tapping.
• Standard pan head profile provides a low-profile finish and reliable clamping force distribution.
• Full compliance with DIN 7981 ensures consistent quality, dimensional accuracy, and interchangeability.
• Right-hand coarse threading enables fast driving and high resistance to vibration loosening.

Professional Applications & Engineering Value

This M2.9 Phillips pan head tapping screw is engineered to solve common fastening challenges in sheet metal assemblies, such as HVAC systems, electronic enclosures, and automotive panels. The 18-8 stainless steel offers excellent resistance to oxidation and chemical exposure, while the thread forming design (Type C) cuts installation time by eliminating the need for separate tapping operations. The coarse thread pitch and fully threaded shank maximize pull-out strength in thin materials, preventing strip-out under dynamic loads. Its DIN 7981 certification guarantees that every screw meets strict industrial standards for dimensional tolerance (Class 2A equivalent) and performance, making it a trusted choice for high-volume manufacturing and maintenance applications where reliability is critical.

Specification Summary & Compliance

This screw features an M2.9 x 16mm size with coarse threads and fully threaded shank, manufactured to DIN 7981 specifications for dimensional accuracy (including head diameter of 5.6mm and head height of 2.2mm). It complies with industry standards for thread forming screws and is made from 18-8 stainless steel, which meets RoHS and REACH environmental regulations. The Phillips No. 1 drive and right-hand thread direction ensure compatibility with standard driving tools, providing consistent performance in sheet metal applications up to 0.025" thickness.
