#4 X 7/8" Type AB Self Tapping Sheet Metal Screws | Oval Head | Phillips Drive | 18/8 Stainless Steel (5000/Pkg.)

Type AB self tapping sheet metal screws designed for metal-to-metal fastening with 18/8 Stainless Steel. Oval head, Phillips drive enables flush seating and compatible tool engagement for bulk installations.

Specs

• Dimensions: Diameter #4; Length 7/8″
• Drive type: Phillips
• Material grade: 18/8 Stainless Steel

Features

• Self tapping design: Cuts its own threads in thin sheet metal, eliminating need for pilot holes and accelerating installation in bulk runs.
• Head style: Oval head provides flush seating beneath countersink and reduces protrusion in finished assemblies.
• Drive compatibility: Phillips drive supports standard hand and power drivers, ensuring consistent torque and broad tool compatibility.
• Material and corrosion resistance: 18/8 Stainless Steel offers corrosion resistance suitable for indoor and outdoor environments; passivation enhances surface stability.
• Bulk packaging: 5,000 count per package.
• Use cases: HVAC ductwork, electrical enclosures, automotive trim, appliance assemblies, and metal fabrication applications requiring secure, flush fasteners.
• Benefits vs alternatives: Reduces installation steps by eliminating pilot holes in thin-sheet metal while delivering reliable thread engagement and vibration resistance.
• Installation tips: Use appropriate torque and driver bit; for thicker metal consider pre-drilling pilot holes or follow material gauge recommendations to minimize tearing and achieve optimal thread formation.
