Value Collection C29868 No.12 Self Drilling Screw 3/4 in

Product Description

The VALUE COLLECTION C29868 is a No. 12 self-drilling screw engineered for fast, reliable fastening without a pre-drilled pilot hole. The No. 3 drill point bores through the substrate and threads in a single operation, reducing labor time on the job. The hex washer head distributes clamping load evenly and resists pull-through, while the hex drive accepts standard hex bit drivers for high-torque installation. Constructed from steel with a zinc-plated finish, the screw resists corrosion in typical indoor and sheltered outdoor applications. Length under head measures 3/4 inch.

This screw is commonly used in light-gauge metal-to-metal and metal-to-substrate fastening in HVAC ductwork fabrication, sheet metal enclosures, equipment panels, and general trade assembly. The No. 3 drill point is rated for thicker gauge material than a No. 2 point, making it appropriate for structural sheet metal connections where a standard tip would walk or fail to penetrate cleanly. HVAC installers, sheet metal workers, and general contractors typically deploy this fastener in high-volume production or field assembly scenarios.

Key Features

• No. 3 drill point self-taps through material without a pilot hole, saving installation steps
• Hex washer head provides broad bearing surface and resists pull-through
• Hex drive accepts standard 5/16-inch hex bit drivers commonly used in trade applications
• Steel construction with zinc-plated finish for corrosion resistance in sheltered environments
• 3/4-inch length under head suits light- to medium-gauge sheet metal connections

Compatibility

Designed as a standard No. 12 self-drilling screw for light- to medium-gauge sheet metal fastening applications typical in HVAC, electrical enclosure, and general sheet metal fabrication work.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, or electricians using a hex-drive bit and an electric screwdriver or impact driver set to an appropriate clutch setting to avoid overdriving. Ensure the workpiece is clamped or secured before driving to prevent movement that can cause the drill point to wander. Do not overdrive — the hex washer head should seat flush against the substrate without deforming the material. Follow applicable codes such as SMACNA standards for ductwork fastener spacing when used in HVAC duct assembly.
