Fastener For Roll Up Doors: Material: Steel and Zinc plated; Length: 2 in. Thread: 1/4-20; Head Style: Flat Countersunk.
Worked well to fabricate a plate on the frame of hot rod that can be bolted on. These coupled with the metal shelf brackets make some really quick, easy, and strong clamp holders!
Welded in nicely, well cut threads, last a long time, with a big wide head to spread the load of the weight of the brackets holding the clamps.
The head recessed just enough into the back of the plywood so that they don't interfere with the french cleats.

Description
This 1/4-20 Elevator Bolts are designed with a wide, countersunk flat head, commonly used in conveyor systems. Our 1/4-20 screw is 2 in. long. Elevator Bolts have a square neck that resists turning when the nut is tightened or removed, and a large head provides a greater bearing surface for soft materials.
