Value Collection R63643846 Sheet Metal Screw No. 12

Product Description

The VALUE COLLECTION R63643846 is a No. 12 round head Phillips sheet metal screw designed for secure fastening in sheet metal fabrication, HVAC ductwork, electrical enclosures, and light structural assemblies. Measuring 1.5 inches under the head, this screw is manufactured from Grade 18-8 stainless steel, providing solid corrosion resistance in humid or mildly corrosive environments. The round head profile offers a low-profile bearing surface with a Phillips drive for fast installation using a standard power driver or hand screwdriver. Sold in a minimum quantity of 100 per order, this fastener suits production and service work where consistent hardware sourcing matters.

This fastener is commonly used by HVAC technicians, sheet metal fabricators, electricians, and plumbing contractors for attaching panels, flanges, covers, and ductwork components. The No. 12 thread size and 1.5-inch length under head make it suitable for moderate-thickness sheet metal gauges found in residential and light commercial mechanical systems. Its stainless steel construction makes it a reliable choice in applications where carbon steel screws would corrode prematurely, such as near condensate drainage areas or exterior mechanical enclosures.

Key Features

• No. 12 thread size for use in standard sheet metal applications
• 1.5-inch length under head provides adequate thread engagement in moderate sheet stock
• Round head Phillips drive compatible with standard No. 2 Phillips bits and drivers
• Grade 18-8 stainless steel construction resists corrosion in humid and wet environments
• Sold in multiples of 100, suitable for production and service shop inventory

Compatibility

Designed as a general-purpose No. 12 round head Phillips sheet metal screw for use in HVAC ductwork, electrical panels, plumbing enclosures, and light sheet metal fabrication where a 1.5-inch stainless fastener is required.

Installation Notes

Sheet metal screws should be installed using a No. 2 Phillips bit at controlled torque to avoid stripping the drive or deforming thin sheet metal. Pre-drilling a pilot hole is recommended for heavier gauge stock to reduce material distortion and extend fastener life. Ensure the work surface is free of burrs before driving to achieve proper seating of the round head. When used in mechanical system enclosures, follow applicable NEC or IFGC requirements for panel integrity and grounding continuity.
