Description

4341SA9E.29
NOS (New / Old Stock) Forged Steel 4" Long Handle Hand Grip Wing Nuts, Wingnuts, with 1/2-13 Threads.  Each bid quantity is for One (1) Wingnut.  You may bid / buy any number, up to the total quantity available above.
These were purchased at an unclaimed freight sale last year, and they were received in an unmarked box.  They all show cosmetic rust spots which do not affect their use.  We used the worst one we could find for pictures, so the ones you receive should be as good or better.  They show sprue lines from the forging process, and the nut and handle appear to be formed into a single unit - not simply a handle welded onto a nut.  They should be ideal for applications requiring more torque than is possible traditional wingnuts, yet with the convenience of tool-free removal.  We listed the grade as "Grade 2" as we do not know exactly what material and heat treatment they are.
