CIMCO Phillips Pan Head Self-Tapping Sheet Metal Screw 3.9 x 19 mm, Zinc-Plated Steel, DIN 7981 190418

For fastening thin metal sheets, plastic components, or light wood in HVAC, electrical enclosure, and general sheet metal work, this CIMCO self-tapping screw drives quickly with a standard PH2 Phillips bit. The pan head sits above the surface, spreading clamping force without countersinking, while the zinc plating provides basic corrosion resistance for indoor and sheltered outdoor use.

Why choose it

The self-tapping thread cuts its own mating thread in thin sheet metal, eliminating the need for pre-tapping in many applications. The Phillips drive provides positive bit engagement to reduce cam-out during installation, and the zinc coating helps prevent rust in dry environments.

Ideal use cases

• Fastening sheet metal enclosures and panels
• Attaching brackets to steel or aluminium profiles
• Securing plastic components to metal frames
• Light-duty wood-to-metal connections

Good to know

For best results, use a pilot hole sized according to the material thickness and hardness. The screw is intended for thin materials; for thicker steel, pre-drilling may be required. Zinc plating is not suitable for continuous outdoor exposure or corrosive environments.
