S-94209A211 M1.6 x 3 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in demanding industrial environments.
• Enhanced torque transmission and reduced cam-out with Torx Plus IP5 drive, allowing for higher tightening precision and tool longevity.
• Reliable thread formation in soft materials like aluminum, brass, and copper, thanks to the tri-lobe shank design that minimizes material stress and prevents stripping.
• Consistent and secure fastening with fully threaded, coarse pitch (0.35mm) metric design, providing excellent holding power in lightweight assemblies.
• Streamlined assembly process with a pan head and blunt tip, enabling easy insertion and flush seating without pre-drilling in many applications.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries.
• Precision length tolerance (-0.8 to 0mm) for exact fit and repeatable performance in high-volume manufacturing.

Professional Applications & Engineering Value

This M1.6 thread forming screw is engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may cause cracking or poor thread engagement. The tri-lobe shank cross-section displaces material smoothly during installation, creating strong, load-bearing threads without chips or debris. Combined with the zinc-plated steel material, it offers excellent resistance to corrosion in electronics, automotive, and precision instrument assemblies. The Torx Plus IP5 drive ensures maximum torque transfer, reducing the risk of driver slippage and damage to the screw head—critical in automated or high-speed production lines. Its fully threaded, coarse pitch metric design provides rapid installation and reliable clamping force, making it ideal for compact, lightweight designs in consumer electronics, telecommunications, and small machinery.

Specification Summary & Compliance

This screw adheres to metric thread standards with M1.6 x 0.35mm coarse pitch and a length of 3mm (-0.8 to 0mm tolerance). It features a right-hand, fully threaded, thread-forming design with a tri-lobe shank and blunt tip. The zinc-plated steel construction meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global supply chains.
