I need some odd little screws to secure the bed knives on reel mowers. They are 1/4-20, 1/2" long with a flat slotted head. What makes them unusual is they have little serrated type lock washers under the heads (tapered to match the head of the screw) and they are hardened (probably case) with black oxide finish.
The reel mower co. charges $1.00 each! Surely I can get them cheaper. Thanks for your help.
