Stewart Fastener 0820APFZ 8x1-1/4 Flat Head Phillips Screw 100pk

Product Description

The STEWART FASTENER 0820APFZ is a Number 8 by 1-1/4-inch flat head Phillips drive Type A sheet metal screw, supplied in a package of 100. Type A thread form features coarse, widely spaced threads engineered to cut cleanly into thin sheet metal and light-gauge steel without pre-tapping. The flat head profile sits flush with the work surface when driven correctly, making it well suited for applications where a smooth finished surface is required. Finished in zinc plating, these screws carry a baseline layer of corrosion resistance appropriate for indoor and protected environments. Installers in HVAC, electrical, and general sheet metal work rely on this screw size and drive style for everyday fastening tasks.

Number 8 by 1-1/4-inch Type A flat head Phillips screws are a common hardware item across residential and light commercial trade work. Typical uses include securing sheet metal panels, HVAC duct components, electrical enclosures, junction box covers, and similar thin-gauge sheet steel assemblies. The Phillips drive is compatible with standard Number 2 Phillips bits. The zinc finish is suited for dry or mildly humid indoor conditions; corrosive or outdoor environments may require stainless or self-sealing alternatives.

Key Features

• Number 8 diameter by 1-1/4-inch length for reliable engagement in light-gauge sheet metal
• Type A thread form with coarse pitch for thread-cutting into thin steel without pre-drilling a tapped hole
• Flat head profile seats flush for a clean, low-profile finish
• Phillips drive accepts standard Number 2 Phillips bits — compatible with most cordless drivers
• Zinc-plated steel construction provides corrosion resistance in dry indoor environments
• Sold in a package of 100 for job-site and shop stock convenience

Compatibility

Designed as a standard Type A sheet metal screw for use in light-gauge sheet steel, thin metal panels, and similar sheet metal fastening applications common in HVAC, electrical, and general sheet metal fabrication work.

Installation Notes

Type A sheet metal screws are installed by HVAC technicians, electricians, and sheet metal workers using a Number 2 Phillips bit in a cordless or corded driver. Pilot hole sizing should match the thread-cutting requirements of the base material thickness — consult applicable fastener charts for light-gauge steel. Do not overtorque; overdriving a flat head screw past flush can strip the material or compromise the joint. Follow all applicable codes for the trade and application.
