Duro Dyne 16016 Magnetic Screw Chuck 5/16 in 6 in Hex Shank

Product Description

The DURO DYNE 16016 is a magnetic screw chuck designed for use with standard drill motors and screw guns in HVAC sheet metal and ductwork applications. Built from hardened steel, it features a permanent magnet that holds screws firmly in place during fastening, reducing dropped fasteners and improving one-handed operation. The chuck accepts screws with a 5/16 inch head and is fitted with a 6 inch long hex shank for secure engagement with the driver. This tool is well suited for sheet metal installers and HVAC technicians who fasten ductwork, flanges, and metal panels on a daily basis.

The 16016 is used in commercial and residential HVAC installation and service work where consistent screw driving into sheet metal is required. The 6 inch shank length provides reach into confined spaces common in duct assembly and air handler installations. The magnetic retention feature makes it practical for overhead or tight-angle fastening where holding a screw manually is not feasible. Sheet metal mechanics and HVAC installers are the primary users of this type of chuck.

Installation Notes

Insert the hex shank fully into the drill motor or screw gun chuck and tighten securely before use. Ensure the driver is set to an appropriate clutch setting for the fastener and material being used to avoid overdriving. Inspect the magnet and shank for wear or damage before each use. This tool does not require disassembly of any system — it is a hand tool accessory used during installation.
