Value Collection 697448PR No. 4 Sheet Metal Screw 5/8 in

Product Description

The VALUE COLLECTION 697448PR is a No. 4 hex washer head sheet metal screw designed for fastening thin metal components in HVAC, electrical, and general sheet metal fabrication work. The slotted drive accepts a standard flat-blade screwdriver, and the Type AB point self-taps into light-gauge steel, aluminum, and similar materials without requiring a pre-drilled pilot hole in many applications. The zinc finish provides basic corrosion resistance for indoor and sheltered installations. Screws are manufactured from 1016/1024 grade steel and conform to ASME B18.6.3, ASME B18.6.4, and SAE J933 standards. This listing covers a minimum order quantity of 100 screws per order.

These screws are commonly used in residential and light commercial HVAC duct assembly, electrical enclosure fabrication, and sheet metal panel attachment. Typical applications include securing duct sections, fastening junction box covers, and assembling metal frames or brackets. The hex washer head provides a bearing surface that resists pull-through on thin-gauge sheet metal, making it a reliable choice for repetitive production or service work where speed and consistency matter.

Key Features

• No. 4 thread size with 5/8 inch length measured under the head
• Type AB point for self-tapping entry into light-gauge sheet metal
• Hex washer head style for use with nut drivers or hex-tip power tools
• Slotted drive accepts standard flat-blade screwdrivers as a backup option
• Zinc finish for basic corrosion resistance in sheltered environments
• Meets ASME B18.6.3, ASME B18.6.4, AISI 1016, and SAE J933 standards

Compatibility

Designed as a general-purpose sheet metal fastener suitable for light-gauge steel, aluminum, and similar thin-material applications typical in HVAC duct work, electrical enclosures, and sheet metal panel assembly.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and electricians using a flat-blade screwdriver or hex nut driver. Ensure material gauge and pilot hole size are appropriate for a No. 4 Type AB screw before driving to avoid thread stripping. Do not overtorque, as the small thread diameter is susceptible to cam-out or shear when power tools are used without a clutch setting. Follow applicable installation standards for the system being assembled.
