I started making custom plywood furniture to replace the nicely designed but cheaply constructed Ikea furniture in our home. With a number of rambunctious children it was important to have strong joints and connections. It was also important to be able to disassemble the bed frames, tables, desks, and hutches for facility in moving. These bolts, along with nut serts provide a means to accomplish all of these objectives. There are still many more projects to go, and these bolts will hold them all together.My application is in a project that is outside on my pool deck. These screws are not showing any sign of corrosion which is critical even in the winter months with the pool covered. I was also impressed by the hex head - none of the screws stopped out even with use of a impact driver. The incoming packaging was odd as they were delivered in a small box in lieu of a plastic bag. I like this as the cardboard is recyclable container.I use these for bed frames I build at Story Builds Woodwork. The price is so much better here and the quality is great.Screws as described. Hard to find this hardware anywhere but online.Exactly as described. Would order againHigh quality, cheaper than McMaster, no complaints.Good bolts, they fasten things togetherThank you
