SS Allen Hex Socket Button Head Screw:M5 x 16 - ISO 7380/A2/Full Thread

The SS Allen Hex Socket Button Head Screw M5 x 16 is a fastener constructed from A2 grade stainless steel, offering reliable corrosion resistance for diverse environments. It complies with the ISO 7380 standard, ensuring precise dimensional accuracy and head geometry for secure driving with hex keys. This full-thread design maximizes the effective engagement length, providing stronger clamping force compared to partially threaded alternatives, which is critical for vibration-resistant applications. Buyers select this grade when balancing cost with durability, as it avoids the higher expense of marine-grade alloys while maintaining performance. To choose the correct variant, verify the nominal diameter is M5 and the nominal length is 16mm, confirming the full thread specification matches your assembly depth requirements.
