Irwin 6849 Hex Die, 9/16-18 NF Thread, 1-7/16 In.

This hex die cuts precise 9/16-18 National Fine (NF) threads on steel, stainless steel, brass, and aluminum. Machine screw dies like this one are essential threading tools for maintenance, repair work, and custom fastener production. The 1-7/16 inch hex size provides comfortable grip and optimal torque transfer, allowing you to cut clean, accurate threads that fit together reliably.

The hardened tool steel (HCS) construction resists deformation and wear through repeated cutting cycles, extending tool life and ensuring consistent thread geometry every time. Because the die can be used with a wrench or socket when space is limited, it adapts to tight work areas and different setups without requiring specialized equipment.
