Duro Dyne 14246 Super Saber Screw 8x0.75 in 250 Pack

Product Description

The DURO DYNE 14246 is a high-head self-drilling screw engineered for one-step fastening in light-to-medium-gauge sheet metal and ductwork applications. Sized at No. 8 x 0.75 inches with a 0.25-inch drive, the oversized high head increases clamping stability and reduces the risk of cam-out during installation. Licensed HVAC sheet metal technicians and ductwork fabricators rely on this screw for fast, secure assembly without pre-drilling. Each pack contains 250 screws, making it practical for production work and service calls alike.

The DURO DYNE 14246 Super Saber Screw is suited for residential and light commercial HVAC ductwork fabrication and installation. It is commonly used when joining sheet metal components such as duct sections, flanges, and fittings where light-to-medium-gauge materials are involved. The high head profile provides positive engagement with standard 0.25-inch hex drivers, speeding up repetitive fastening tasks on the job site or in the shop.

Key Features

• One-step self-drilling design eliminates the need for pre-drilling in light-to-medium-gauge sheet metal

Compatibility

Designed as an OEM-style fastener for light-to-medium-gauge sheet metal ductwork fabrication and HVAC assembly applications.

Installation Notes

Installation is typically performed by licensed sheet metal workers or HVAC technicians using a standard 0.25-inch hex driver or drill with a hex bit attachment. Ensure all duct sections are properly aligned and supported before driving screws to prevent material distortion. Follow local mechanical codes and manufacturer assembly guidelines for screw spacing and penetration depth. Do not overdrive screws, as this can strip the material or compromise the seal at duct joints.
