These are stainless version of our 3/8" x 16 thread socket head cap screws (we call them bolts) that you see in climbing gyms. Tighten them with a standard 5/16 hex (allen head) t-wrench or impact bit. These work with stainless climbing wall t-nuts.
Recommend Stainless Steel Bolts and Stainless Steel T-Nuts instead.

Thread: 1.5" bolts are fully threaded. 2" and up will have an unthreaded neck between the threads and cap head. These neck sizes vary by bolt length.
Standard vs Metric: Standard 3/8" bolts are what we use in the US, Metric M10 bolts and t-nuts are used in the UK and Europe. M10 is slightly larger than 3/8". 3/8" bolts will actually work in M10 t-nuts, but because the Standard 3/8" bolt shaft is a little smaller than a Metric M10 bolt shaft, a Standard bolt in a Metric t-nut is a bit more likely to strip out the threads. Metric M10 bolts DO NOT fit in Standard T-Nuts, or sometimes you can get them in but they'll usually get stuck. It's always recommended to make sure you have the correct hardware that fits together correctly.
