Value Collection TKHWI-1401250-3-100BX Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWI-1401250-3-100BX is a 1/4 inch self drilling screw designed for fast, reliable fastening without a pre-drilled pilot hole. Featuring a hex washer head and hex drive, this screw is driven with a standard hex bit or nut driver. The 1-1/4 inch length under head and number 3 drill point make it well suited for light-gauge steel framing, sheet metal panels, metal roofing, and similar structural or enclosure applications. Constructed from steel with a zinc-plated finish for corrosion resistance, this screw is a go-to fastener for HVAC duct work, metal building assembly, and general trade fabrication tasks. Sold in a box of 100.

This screw is a standard choice for HVAC installers, sheet metal fabricators, electricians, and general contractors working with light-gauge metal substrates. The hex washer head provides a broad bearing surface that resists pull-through on thin metal, and the zinc coating offers basic protection against moisture and oxidation in typical indoor and sheltered outdoor installations. The number 3 drill point is matched for use in light to medium gauge steel without pre-drilling.

Key Features

• 1/4 inch diameter with 1-1/4 inch length under head for consistent fastening depth in light-gauge applications
• Number 3 drill point self-drills through light to medium gauge steel without a pilot hole
• Hex washer head provides wide bearing surface and reduces pull-through risk
• Hex drive accepts standard 1/4 inch hex bits and nut drivers for power tool use
• Steel construction with zinc-plated finish for basic corrosion resistance
• Sold in a 100-piece box for high-volume job site use

Compatibility

Designed as a standard 1/4 inch hex washer head self drilling screw for use in light-gauge steel framing, sheet metal ductwork, and metal panel fastening applications common in HVAC, electrical, and general construction trades.

Installation Notes

Install using a power drill or impact driver fitted with a 1/4 inch hex bit or magnetic nut driver. Power down or de-energize any adjacent electrical or mechanical systems before fastening into enclosures or duct assemblies. Avoid over-driving, which can strip the drill point or distort the workpiece. Follow applicable building code requirements, including SMACNA duct construction standards where relevant for HVAC applications.
