Value Collection TKHWI-1200870-4-100T Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWI-1200870-4-100T is a No. 12 self-drilling screw designed for fast, reliable fastening in metal-to-metal and light structural applications. It features a hex washer head driven by a hex drive and a No. 4 drill point that cuts its own pilot hole without pre-drilling. The shank measures 7/8 inches in length under the head. Constructed from steel with a zinc-plated finish, it resists corrosion in typical indoor and light outdoor environments. Electricians, HVAC installers, sheet metal workers, and general contractors commonly use this screw type for securing panels, brackets, and ductwork components.

This screw is suited for sheet metal fabrication, HVAC duct assembly, electrical enclosure installation, and light structural metal fastening. The hex washer head provides a wide bearing surface that distributes clamping load and reduces material distortion. The No. 4 drill point is designed for use in light-gauge steel applications where speed and consistency are priorities on the job.

Key Features

• No. 12 screw size for medium-duty metal fastening applications
• No. 4 drill point cuts its own pilot hole in light-gauge steel
• Hex washer head with hex drive for positive tool engagement and high torque transfer
• 7/8 inch length under head suits standard light-gauge sheet metal assemblies
• Steel construction with zinc-plated finish for corrosion resistance
• Inch measurement system for compatibility with standard trade tooling

Compatibility

Designed as a standard No. 12 self-drilling screw for light-gauge sheet metal and general trade fastening applications where a hex washer head and No. 4 drill point are specified.

Installation Notes

Installation is performed with a hex-drive bit in a variable-speed drill or impact driver set to an appropriate clutch setting to avoid overdriving. Confirm material gauge is within the rated capacity of a No. 4 drill point before use. Always wear appropriate eye protection when driving self-drilling fasteners. Follow applicable codes including SMACNA guidelines for duct assembly or NEC requirements for electrical enclosure work where fastener type is specified.
