Value Collection R63308442 No. 6 Sheet Metal Screw 3/8 in

Product Description

The VALUE COLLECTION R63308442 is a No. 6 hex washer head sheet metal screw intended for fastening light-gauge sheet metal and similar thin materials in HVAC, electrical, and general trade applications. The slotted drive accommodates standard flat-blade or combination screwdrivers and nut drivers. Manufactured from Grade 18-8 stainless steel, this screw resists corrosion in moderately wet or outdoor-adjacent environments. The 3/8-inch length is measured under the head, making it a compact fastener suited for thin-gauge assemblies where pull-through resistance and a broad bearing surface are needed. Installation and maintenance technicians across multiple trades use this fastener for ductwork, panels, enclosures, and equipment housings.

This screw is well suited for light commercial and residential trade work involving sheet metal duct connections, electrical enclosure assembly, and equipment panel attachment. The hex washer head style provides a wide clamping surface that resists pull-through on thin substrates and can be driven with a hex-drive nut driver or socket, which is common in HVAC and sheet metal work. The 18-8 stainless steel grade makes it appropriate for applications where mild corrosion resistance is required, such as rooftop equipment, outdoor panels, or humid mechanical rooms.

Key Features

• No. 6 thread size is a common trade-standard fastener diameter for sheet metal applications
• Inch measurement system; thread size and length conform to standard inch fastener specifications

Compatibility

Designed as a standard-duty sheet metal fastener for use in light-gauge sheet metal assemblies, equipment enclosures, ductwork, and panel applications common to HVAC, electrical, and plumbing trades.

Installation Notes

Sheet metal screws are installed by licensed HVAC technicians, sheet metal workers, and electricians using a flat-blade screwdriver or hex nut driver. Verify substrate gauge and material before selecting screw length and thread type to ensure adequate engagement without breakthrough. Pilot holes may be required in harder or thicker substrates to prevent material distortion. Stainless steel fasteners should not be mixed with dissimilar metals in applications where galvanic corrosion is a concern.
