Fusion stainless steel climbing hangers bought from https://amzn.to/2JLoBq2 are rated for 30kn and broke at 31.10kn and 29.56kn and 31.22kn. They sell zinc plated bolts - please don’t use those outside! At over $5 a piece they are not really a deal. Tested with a Simpson strong tie TitenHD concrete screw from https://amzn.to/2WCBcBf in a ⅜” hole. Those are amazing bolts, especially if looking for a temporary anchor (assuming you can use power tools legally - not national parks). Please don't bolt if you don't need to and use titanium if near the ocean and never use plated steel bolts outside. With Bobby Hutton
