Value Collection TKHWI-1403000-3-100B Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWI-1403000-3-100B is a 1/4 inch self-drilling screw designed for fast, reliable fastening in light steel and metal construction applications. It features a hex washer head with a hex drive and a number 3 drill point that bores its own pilot hole, eliminating the need for pre-drilling. The screw body is manufactured from AISI 1016/1024 steel and finished with a zinc plating for basic corrosion resistance. At 3 inches in length under head, it provides solid thread engagement in typical metal-to-metal or metal-to-substrate assemblies. This package contains 100 screws, sold as a single unit quantity.

These self-drilling screws are suited for structural and non-structural metal framing, metal cladding, HVAC ductwork, and general sheet metal assembly in both residential and light commercial construction. The number 3 drill point is appropriate for thicker gauge steel substrate, making these fasteners a practical choice for field installation work where speed and consistency matter. Licensed tradespeople and experienced contractors working metal framing, roofing, or mechanical enclosures will find this a standard utility fastener.

Key Features

• Number 3 drill point self-drills through heavier gauge steel without pre-drilling
• Hex washer head with hex drive provides positive tool engagement and bearing surface
• 1016/1024 steel construction meets AISI, ASME B18.6.3, and SAE J78 standards
• Zinc-plated finish provides basic corrosion protection in dry or sheltered environments
• 3 inches length under head suits medium-depth metal fastening applications
• Sold in a 100-piece minimum order quantity for field and shop use

Compatibility

Designed as a standard 1/4 inch self-drilling fastener for use in metal framing, sheet metal, and light structural steel applications where a number 3 drill point and hex washer head configuration are specified.

Installation Notes

Installation is performed with a hex-drive bit and an electric or pneumatic screwdriver set to an appropriate torque clutch setting to avoid overdriving. Power down or de-energize any adjacent systems before fastening near electrical panels or conduit. Follow applicable building codes and manufacturer specifications for fastener spacing and edge distance in structural applications. Do not use in applications requiring stainless steel or higher-grade corrosion resistance without verifying the zinc-plated finish is adequate for the environment.
