Review on Stainless Machine Finish One Way Threads Fasteners by Michael Glassburn

As the screws were exposed to the elements and passers by I was concerned that someone wanting to access the contents of the shed could remove the Phillips head or Torx key . Absolutely nothing is 100% theft proof, but for the money these security screws are a perfect deterrent. I feel sorry for those who have to loosen these screws in the future!
