Safety Tips


These are actually designed to tighten collars over flared pipes, for example the brake lines on a car. However you can still use one of these for any standard hex head. The advantage of that is that it spreads the load onto more corners of the head than the standard spanner shape, decreasing the risk of rounding the shoulders of the head.
