L H Dottie Co DDSMS8112 Sheet Metal Screw No. 8

Product Description

The L H Dottie Co DDSMS8112 is a No. 8 sheet metal screw measuring 1.5 inches in length. Sheet metal screws in this size range are designed for fastening thin metal panels, brackets, and ductwork components in HVAC, electrical, and light mechanical assemblies. The self-tapping thread profile cuts into sheet metal without a pre-tapped hole, making installation straightforward in field and shop settings alike. This screw is sold as a single unit and is suited for applications where individual quantity purchasing is required.

This fastener is commonly used in residential and light commercial HVAC duct fabrication, electrical enclosure assembly, and general sheet metal work. It is appropriate for securing thin-gauge metal panels, junction box covers, access door frames, and similar components where a No. 8 diameter and 1.5-inch length provide adequate grip and holding strength without over-penetrating the material.

Key Features

• No. 8 diameter sheet metal screw for thin-gauge metal applications
• 1.5-inch length provides reliable thread engagement in standard sheet metal thicknesses
• Self-tapping design cuts threads on installation without requiring a pre-tapped hole
• Single-unit packaging supports exact-quantity purchasing

Compatibility

Designed as a standard No. 8 sheet metal screw suitable for general HVAC ductwork, electrical enclosures, and light mechanical sheet metal assemblies.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and sheet metal workers using a power drill or hand screwdriver with the appropriate Phillips, hex, or slotted bit depending on the head style. Always de-energize and lock out electrical enclosures before fastening into or around live panels. Pilot holes may improve alignment and reduce material distortion on thinner gauges. Follow applicable NEC or IFGC guidelines when fastening within regulated assemblies.
