Some ACE Hardware stores have them, and they can get them for you. I know, because I am in the wholesale website where the stores buy from the warehouse that is down in Colorado Springs. You can also find them at commercial fasteners places, like Fastenal or Colorado Fasteners. I buy them at CD Fasteners in Fort Collins.
It is a 3/4″ eyebolt. I am building the GL Liberty 4. I want to put the K1440 that I won as a “Never Ending Raffle” to go use. This is one of my many long term projects; I will eventually get there. I don’t think that with this configuration that this will be a low and slow project.
McGuckins is a good choice, and yes, they are very proud of their prices! Curious to hear though, of alternatives.
If I cannot find what I am seeking locally, I hit the net. I start with “Google” and then go to the ”shopping” tab. I might put in here forged eye bolts or 3/4″ forged eye bolts. You should also be able to find this in a rigging supply site, also. I hope this helps. Bear
Accepts PayPal. I buy eye nuts from them. Hard to find them on their site due to their mediocre search tool, but they are cheap. Search under “eye”. Shipping isn’t cheap, so order ten or more. Each one is under $4.00 for the quarter inch ones including shipping. I like the eye nuts better than the eye bolts. I get quarter inch, five sixteenth, and three eighth inch ones. They don’t leave a big screw sticking into your eBay or NC.
