Value Collection R55000158 No. 12 Self Drilling Screw

Product Description

The VALUE COLLECTION R55000158 is a No. 12 self drilling screw with a hex washer head and hex drive, manufactured from Grade 410 stainless steel. The No. 3 drill point allows this fastener to cut through light-gauge metal without a pre-drilled pilot hole, reducing installation steps on sheet metal assemblies, HVAC ductwork, electrical enclosures, and similar fabrication work. The 1-1/4 inch length under head suits moderate material stack thicknesses common in trade applications. Grade 410 stainless steel provides good corrosion resistance and mechanical strength in both indoor and outdoor service environments.

This screw is well suited for attaching sheet metal panels, flanges, and brackets in HVAC, plumbing, and electrical trade work. The hex washer head distributes clamping load evenly and seats flush against sheet metal surfaces, while the hex drive accepts standard 5/16-inch hex-bit drivers and nut drivers already common in most technicians tool kits. The No. 3 drill point is rated for light to medium gauge steel substrates. These screws are packaged individually with a minimum order of 100 pieces, making them appropriate for job-site replenishment or shop stock.

Key Features

• No. 3 drill point drills its own pilot hole in light to medium gauge steel
• Grade 410 stainless steel construction for corrosion resistance
• Hex washer head distributes load and reduces pull-through risk
• Hex drive accepts standard 5/16-inch bit drivers for fast installation
• 1-1/4 inch length under head suits moderate material stack applications
• Inch measurement system; No. 12 screw diameter

Compatibility

Designed as a standard No. 12 self drilling fastener for light to medium gauge sheet metal applications common in HVAC, electrical, and general sheet metal fabrication work.

Installation Notes

Installation is performed with a hex-bit driver or nut driver at controlled speed to avoid overdriving and stripping the drill point. Apply consistent axial pressure when starting the drill point to prevent walking on smooth metal surfaces. Do not exceed the rated material thickness for the No. 3 drill point, as this can stall or break the tip. Follow applicable local building and mechanical codes for fastener specifications when used in code-governed assemblies.
