Value Collection R55000172 No.14 Self Drilling Screw 2.5in

Product Description

The VALUE COLLECTION R55000172 is a No. 14 self drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. It features a hex washer head with an integrated hex drive and a No. 3 drill point that cuts its own pilot hole, eliminating the need for pre-drilling. The screw measures 2.5 inches under the head and is manufactured from Grade 410 stainless steel, providing corrosion resistance suited to both indoor and outdoor service environments. HVAC installers, sheet metal workers, and general tradespeople use this fastener where a self-starting, corrosion-resistant screw is required in moderate-gauge metal work.

This screw is commonly used in residential and light commercial construction and mechanical installation work. Typical applications include attaching sheet metal ductwork, securing metal framing, fastening electrical enclosures, and anchoring equipment brackets. The No. 3 drill point is rated for moderate-gauge steel. The hex washer head provides a wide bearing surface that resists pull-through, and the hex drive allows use with standard power drivers, reducing cam-out compared to slotted or Phillips configurations.

Key Features

• No. 3 self drilling point eliminates pre-drilling in moderate-gauge metal
• Hex washer head delivers a wide bearing surface and reduced pull-through
• Hex drive compatible with standard 5/16-inch nut drivers and power tools
• Grade 410 stainless steel construction for corrosion resistance
• 2.5-inch length under head suits thicker substrate and stacked-material assemblies
• No. 14 screw size provides high clamping force for metal fastening tasks

Compatibility

Designed as a general-purpose OEM-style replacement or stock fastener for sheet metal, HVAC ductwork, light structural metal framing, and similar moderate-gauge metal assembly applications requiring a No. 14 self drilling screw.

Installation Notes

Installation is typically performed by sheet metal workers, HVAC technicians, or electricians using a 5/16-inch hex driver bit in a power drill or impact driver. Ensure the workpiece is securely clamped before driving to prevent material shift. Do not overdrive the screw, as stripping the hex washer head or deforming thin sheet metal can compromise the joint. Follow applicable codes such as the SMACNA duct construction standards or local building codes when fastening structural or mechanical assemblies.
