Durodyne 14191 Self-piercing Screw 10 Thread 1 in Hex Head

Product Description

The DURODYNE 14191 is a self-piercing screw from the Pro Point Series, designed for fast, reliable fastening in sheet metal ductwork and HVAC fabrication applications. Built from steel with an unslotted hex head, this screw bores through light-gauge metal without a pre-drilled pilot hole, speeding up installation on duct assemblies, plenums, and sheet metal enclosures. The number 10 thread size and 1 inch overall length make it a compact, versatile fastener suited to the tight clearances common in duct construction and HVAC panel work. HVAC sheet metal workers and duct fabricators are the primary installers of this type of fastener.

The 14191 is well-suited for residential and light commercial HVAC ductwork fabrication, including rectangular duct assembly, fittings, and equipment panel attachment. The self-piercing tip eliminates the need for separate drilling operations, making it a standard choice on duct boards and sheet metal gauges commonly found in air distribution systems. Its 5/16 inch drive hex head is compatible with standard hex-head nut drivers and impact drivers used daily in the field.

Key Features

• Self-piercing tip eliminates pilot hole drilling on light-gauge sheet metal
• Number 10 thread size for secure grip in standard duct gauges
• 1 inch overall length suits tight clearances in duct assembly
• Unslotted hex head accepts 5/16 inch nut driver or hex bit
• Steel construction for durability in sheet metal fastening applications

Compatibility

Designed as an OEM-style replacement fastener for light-gauge sheet metal ductwork and HVAC fabrication applications requiring a number 10 self-piercing screw.

Installation Notes

Installation is typically performed by HVAC sheet metal mechanics and duct fabricators using a standard nut driver or impact driver with a 5/16 inch hex bit. Ensure the mating sheet metal is within the appropriate gauge range for self-piercing fasteners before driving. Power down any air handling equipment before accessing duct sections for fastener installation or repair. Do not overdrive — excess torque can strip the thread engagement in thin sheet metal.
