Hex Head Set Screws M18x50x1.5 8.8 MF PLN 961

A hex set screw and nut has uniform threads ? meaning they are not tapered like the thread on wood screws ? and can be used to fasten objects together by inserting the screw from the one end and securing it with the nut on the other end. It can be used to secure wood to wood, metal to metal, metal to wood as well as wood to metal.nThe hex set screw and nut keep objects together by means of friction and takes place when the nut is tightened, thus compressing everything together. To tighten the nut requires a tool of some sort, like a socket and wrench or a spanner.nIn some cases, while tightening the nut, the bolt will turn along with it. If this happens it would require a second spanner or wrench to hold-on to the bolt while the nut is tightened at the other end.
