I have a 4×6 running left and right in the attic above my garage and want to hand a 100lb heavy bag.
Many use an eye bolt and go through the wood with a nut on top. I was trying to find an 10” eye bolt that was all threaded so I can put a nut and malleable washer on the top and bottom. Well finding an all threaded eye bolt is impossible or they run $30+ online.
Got any ideas?
My dad said to use this with four 3/8×2” lag bolts. I don’t like the idea of lag bolts. Will 4 of them hold a 100lb bag? I feel much more comfortable drilling through the beam with a nut on top.
I was also thinking about using one of these and drilling through the beam and use 8” long bolts with lock nuts.
Lastly, I could just get about 2ft of chain and wrap it around the beam.
My main concern is if lag screws are strong enough. I could use 4” long screws.
