• Compliance with environmental regulations including RoHS 3 and REACH for global industrial use

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening and corrosion resistance are critical. The thread forming design (A/AB type) creates durable threads by displacing material rather than cutting it, resulting in stronger connections that resist vibration loosening. The Phillips drive system ensures consistent installation torque while the fully threaded 0.138" diameter with 18 TPI provides maximum holding power in thin materials. Ideal for HVAC systems, electrical enclosures, and metal fabrication, these industrial screws deliver predictable performance in automated assembly environments while meeting strict environmental compliance standards for modern manufacturing requirements.

Specification Summary & Compliance
