Key Features & Benefits at a Glance
- Superior torque transmission with T40 Torx drive design, reducing cam-out risk and tool wear during high-torque applications
- Exceptional corrosion resistance through 18-8 stainless steel construction with passivated surface treatment, ideal for harsh environments
- Reliable thread engagement with Class 6g tolerance coarse threading (M8 x 1.25mm), ensuring consistent fastening in industrial assemblies
- Enhanced clearance and aesthetic appeal from the rounded button head profile, providing a low-profile finish without sharp edges
- High mechanical strength with 100,000 psi tensile strength, supporting demanding applications where vibration resistance is critical
- Full regulatory compliance meeting ISO 7380 standards, RoHS 3, and REACH requirements for global industrial use
- Complete thread coverage along the 30mm length, enabling secure fastening across varying material thicknesses
Professional Applications & Engineering Value
Engineered for precision industrial applications, these M8 metric screws with Torx T40 drive address critical challenges in machinery assembly, automotive components, and electronic enclosures. The 18-8 stainless steel material combined with passivated finish provides lasting protection against chemical exposure and atmospheric corrosion, significantly reducing maintenance cycles in demanding environments. The coarse thread pitch (1.25mm) and Class 6g thread fit ensure rapid installation and reliable performance in materials prone to vibration loosening. The rounded button head design offers both aesthetic cleanliness and practical safety by eliminating sharp protrusions, while the fully threaded shank maintains consistent clamping force across joint variations.
Specification Summary & Compliance
This M8 x 1.25mm x 30mm screw features Class 6g thread tolerance with right-hand coarse threading and complies with ISO 7380 manufacturing specifications. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental compliance for international industrial distribution. Manufacturing controls maintain dimensional consistency for the 14mm head diameter and 4.4mm head height according to standardized metric parameters.
