I agree about getting a replacement from a hardware store or at a national DIY type store. I must admit I have never lost the bolt, but I have lost a couple nuts while detecting. I learned to check them every time I pull my detector out for use. It's part of my PMCS routine (PMCS = Preventative maintenance Checks and Service). Kellyco is a business and probably has a minimum sale price before you get free shipping. If not they would be nickel and dimed to death and lose money. Remember shipping companies charge a fee. When I sent my F75LTD in for the DST upgrade back in 2015 I bought a 3 fisher replacement screw/nut sets and they shipped them back with my machine, no additional shipping charges. 2 years later I lost the on/off knob. They mailed me 2 for free. Sure it took a couple extra days for me to recive them, but I didn't mind that they came vial US Mail.
