Professional Applications & Engineering Value
These M3.5 metric screws with Torx button head configuration address critical assembly challenges in precision industries. The 18-8 stainless steel material combined with passivated finish creates a robust barrier against oxidation and chemical exposure, making these fasteners ideal for electronics, medical devices, and automotive components where corrosion resistance is paramount. The T10 Torx drive system eliminates slippage during high-torque applications, preventing damage to sensitive components while ensuring consistent clamping force. With fully threaded M3.5x0.6mm coarse pitch configuration and Class 6g thread fit, these screws provide reliable engagement in both metallic and composite materials, reducing the risk of cross-threading in high-volume production environments.
Specification Summary & Compliance
This fastener features precision metric threading with M3.5 diameter, 0.6mm pitch, and Class 6g thread fit tolerance per ISO standards. Manufacturing complies with ISO 7380 specifications for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
