Value Collection TKHWBSI-1402000-3-050B Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWBSI-1402000-3-050B is a 1/4 inch self-drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. The hex washer head with an integrated neoprene washer creates a weather-resistant seal on contact, making it well suited for roofing panels, metal cladding, and HVAC sheet metal work. The screw features a No. 3 drill point that bores its own pilot hole, eliminating a separate drilling step. Constructed from steel with a zinc-plated finish for corrosion resistance, this fastener measures 2 inches in length under the head. Each package contains 50 screws, with a minimum order quantity of 50 units per order.

This self-drilling screw is commonly used by HVAC technicians, sheet metal workers, and general contractors for attaching light-gauge steel framing, ductwork, roofing panels, and metal building components. The neoprene washer backing helps prevent water infiltration at the fastener point, making it a standard choice for exterior metal panel installations. The hex drive style is compatible with standard hex-bit drivers and nut drivers used in trade and commercial construction settings.

• 2-inch length under head suits a range of light- to medium-gauge metal fastening tasks
• Hex drive compatible with standard hex-bit drivers and magnetic nut setters
• Sold in 50-unit packages, minimum order quantity of 50

Compatibility

Designed as a standard 1/4 inch hex washer head self-drilling screw suitable for light- to medium-gauge steel applications including HVAC ductwork, roofing panels, and metal framing assemblies.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or general contractors using a hex-bit driver or nut setter rated for self-drilling fasteners. Apply consistent, steady pressure when driving to allow the drill point to penetrate cleanly without cam-out or fastener spin. Do not overtighten, as excessive torque can compress and damage the neoprene washer, reducing its sealing effectiveness. Follow applicable building codes and manufacturer panel guidelines for fastener spacing and edge distance.
