Value Collection TKHWBSI-1201500-3-025B No. 12 Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWBSI-1201500-3-025B is a No. 12 hex washer head self-drilling screw designed for fast, reliable fastening in steel and similar substrates without a pre-drilled pilot hole. Built from steel with a zinc-plated finish for corrosion resistance, this screw features a No. 3 drill point that cuts its own mating thread on contact. The hex washer head provides a broad bearing surface and is driven with a standard hex driver bit. Length under head measures 1-1/2 inches. Sold in a minimum quantity of 25 pieces per order, making it practical for both service calls and larger installation jobs.

This screw is suited for light-gauge metal fastening applications commonly encountered in HVAC ductwork assembly, electrical enclosure mounting, metal framing, and general sheet metal work. The self-drilling tip eliminates a separate drilling step, reducing installation time in the field. The hex washer head and hex drive combination is compatible with standard power drivers and nut setters used by HVAC technicians, electricians, and sheet metal fabricators.

Key Features

• No. 3 drill point self-taps and self-drills without a pilot hole
• Hex washer head provides wide bearing surface to resist pull-through
• Hex drive accepts standard nut setter or hex driver bits
• Zinc-plated steel construction offers corrosion resistance for typical indoor and moderate-exposure applications
• 1-1/2 inch length under head suits common light-gauge sheet metal thicknesses
• Sold in multiples of 25 for efficient job-site procurement

Compatibility

Designed as a general-purpose No. 12 self-drilling fastener suitable for light-gauge steel sheet metal assemblies, HVAC ductwork, electrical enclosures, and similar metal-to-metal fastening applications where a No. 3 drill point is appropriate.

Installation Notes

Installation is performed with a standard hex nut setter or hex driver bit fitted to a power drill or impact driver. Ensure the workpiece is secured before driving to prevent walking of the drill point. Do not overdrive — excessive torque can strip the thread or deform the washer head bearing surface. Follow applicable codes, including SMACNA guidelines for duct fastening, when used in HVAC ductwork assemblies.
