S-90258A221 M4 x 16 mm DIN 966, ISO 7047 Stainless Steel Phillips Oval Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for long-lasting performance in harsh environments
• High tensile strength of 70,000 psi ensures reliable fastening under substantial mechanical loads
• Precise Class 6g thread fit guarantees smooth installation and secure connections in metric applications
• Optimized Phillips drive (No. 2) provides efficient torque transfer and reduces cam-out during assembly
• Standard oval head profile offers a flush, professional finish when countersunk into materials
• Full threading along the 16mm length enables maximum grip and uniform stress distribution
• Compliance with DIN 966/ISO 7047 standards ensures dimensional accuracy and international interoperability

Professional Applications & Engineering Value

These M4 metric flat head screws deliver exceptional engineering value through their 18-8 stainless steel composition and passivated surface treatment, which collectively combat corrosion in demanding industrial settings like machinery assembly, electrical enclosures, and automotive components. The coarse 0.7mm pitch thread and Class 6g tolerance facilitate quick, secure fastening in sheet metal, plastics, and soft materials, reducing installation time while preventing cross-threading. The oval head design with 90° countersink angle sits flush to eliminate protrusions, making these Phillips drive screws ideal for applications where aerodynamic profiles or safety are priorities. Their fully threaded 16mm length ensures consistent clamping force across joints, addressing common vibration-induced loosening issues in dynamic operational environments.
