Countersunk Phillips Tri-Lobular Screw | Self-Tapping | Zinc
Countersunk Phillips Tri-Lobular Thread ScrewEngineered for flush-mount applications requiring vibration-proof fastening. The countersunk head provides a smooth surface finish, while the Phillips drive ensures efficient torque transfer. Tri-lobular thread technology creates permanent mechanical locking through cold-forming deformation, excee
ding ISO 16130 vibration resistance standards. Ideal for aerospace, precision instruments, and automotive chassis.
Key Features
✅ Flush Surface：90°±2° head angle (ISO 10642) for seamless embedding
✅ Zero Loosening：Residual clamping force >85% after 50,000 vibration cycles
✅ High Torque Transfer：Phillips drive compatible with ISO 8764-1 PH bits, 1.5x cam-out resistance vs
standard screws
✅ Military-Grade Materials：Ti6Al4V titanium / Alloy steel Grade 12.9 / A4-80 stainless steel
