Torx Pan Head Tri-Lobular Screw | Self-Tapping | Zinc Plated
Torx Pan Head Tri-Lobular Thread Screw
Engineered for high-torque anti-loosening applications. Torx drive provides 6-point engagement for 300% higher torque transfer vs Phillips, while tri-lobular thread creates permanent mechanical locking through cold-forming. Pan head ensures even load distribution. Compliant with ISO 14583, ideal for automotive engines, industrial robots, and heavy machinery.
Key Features
✅ Max Torque Transfer：Zero cam-out risk at ≥10N·m torque (M6 size)
✅ Permanent Locking：＞90% residual clamping force after 100k vibration cycles
✅ Robotic Installation：Torx TR drive compatible with auto-feed systems
✅ Military-Grade Durability：A4-80 SS (2000h salt spray) / Titanium (500℃)
