Stewart Fastener J0820ACHZ Zinc Hex Self-tap Screw No. 8

Product Description

The STEWART FASTENER J0820ACHZ is a No. 8 zinc-plated hex head self-tapping screw measuring 1-1/4 inches in length, sold in jars of 100 screws per unit. Self-tapping screws cut their own threads as they are driven, eliminating the need for a pre-tapped hole in sheet metal, light-gauge steel, and similar substrates. The hex head drive style allows use with a standard nut driver or hex bit, providing consistent torque application. These screws are used across HVAC, electrical, plumbing, and general trade applications where secure, fast fastening in thin materials is required.

These screws are well suited for light-gauge sheet metal work common in HVAC duct fabrication, equipment panels, electrical enclosures, and other trade installations. The zinc plating provides corrosion resistance appropriate for indoor and sheltered outdoor applications. The 100-count jar format keeps fasteners organized and accessible on the job site or service van, making them practical for both service technicians and installation crews handling repetitive fastening tasks.

Key Features

• No. 8 diameter self-tapping design cuts threads on installation without pre-tapping
• 1-1/4 inch length suits light-gauge sheet metal and panel fastening
• Zinc plating provides corrosion resistance for indoor and sheltered applications
• Hex head drive compatible with standard nut drivers and hex bit drivers
• 100-count jar packaging keeps fasteners contained and ready for field use

Compatibility

Designed as a general-purpose self-tapping fastener for light-gauge sheet metal, equipment panels, and similar substrates commonly encountered in HVAC, electrical, and mechanical trade work.

Installation Notes

Installation is performed with a nut driver or hex-head bit at appropriate drill speed to avoid stripping the self-tapped thread. Ensure the substrate material and gauge are appropriate for a No. 8 self-tapping screw before driving. Do not overdrive; stop when the head seats flush to avoid damaging the fastener or substrate.
