- Enhanced assembly efficiency with integrated flange eliminating the need for separate washers
- Secure, high-torque fastening enabled by 3mm hex socket drive preventing cam-out
- Consistent thread engagement with fully threaded Class 6g fit ensuring reliable clamping force
- High mechanical strength supporting demanding applications with 70,000 psi tensile strength
- Streamlined installation through low-profile button head design requiring minimal clearance
- Global compliance assurance meeting ISO 7380 standards and environmental regulations (RoHS 3, REACH)
Professional Applications & Engineering Value
Engineered for precision assemblies where corrosion resistance and structural integrity are critical, these M5 metric screws solve common industrial challenges. The 316 stainless steel material combined with passivated finish provides exceptional protection against chemical exposure and atmospheric corrosion, making these flanged button head screws ideal for marine equipment, food processing machinery, and pharmaceutical installations. The integrated flange design distributes clamping pressure over wider surface areas, preventing surface damage while the coarse thread pitch (0.8mm) ensures rapid installation in soft materials and vibration-resistant performance. With fully threaded Class 6g precision, these hex socket drive fasteners deliver consistent torque transmission and reliable seating in tight-clearance applications.
Specification Summary & Compliance
This M5 x 0.8mm x 8mm fastener maintains Class 6g thread fit tolerance per metric standards with coarse thread spacing for optimal engagement. Manufacturing conforms to ISO 7380 specifications ensuring dimensional accuracy and interchangeability. The product demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, validated through material documentation.
