Professional Applications & Engineering Value
This M4 metric screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The 18-8 stainless steel material, combined with a passivated finish, provides exceptional resistance to rust and chemicals, making it suitable for outdoor equipment, marine hardware, and food processing machinery. The flanged button head with a wide profile distributes clamping force evenly, preventing surface damage and simplifying installation in tight spaces. Its hex drive and coarse thread enable rapid tightening with standard tools, reducing labor time in high-volume production lines. Ideal for flanged mounting in electronics, automotive, and machinery assemblies, this screw ensures durable, maintenance-free performance in demanding industrial applications.
Specification Summary & Compliance
This screw adheres to metric thread standards with M4 size, 0.7mm pitch, and Class 6g thread fit for precise dimensional accuracy. It is fully threaded with a length of 16mm and flange diameter of 9.4mm. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets stringent environmental and safety regulations for industrial use.
