The basic steps in the friction drilling process: A.Applying pressure. B.Tool heats target and melts through it. C.Screw thread tapping. Friction drilling is a method of making holes in metal in which the material is pushed out of the way with the aid of heat from friction.
The preload target can be achieved by a variety of methods: applying a measured torque to the bolt, measuring bolt extension, heating to expand the bolt then turning the nut down, torquing the bolt to the yield point, testing ultrasonically, or by applying a certain number of degrees of relative rotation of the threaded components. Each method ...
The edges of shafts and holes are chamfered (beveled). The chamfer forms a guide for the pressing movement, helping to distribute the force evenly around the circumference of the hole, to allow the compression to occur gradually instead of all at once, thus helping the pressing operation to be smoother, to be more easily controlled, and to ...
A self-tapping machine screw is similar to a machine screw, except the lower part of the shank is designed to cut threads as the screw is driven into an untapped hole. The advantage of this screw type over a self-drilling screw is that, if the screw is reinstalled, new threads are not cut as the screw is driven. set bolt: tap bolt, setscrew
It is often used by mechanics to loosen larger screws, bolts and nuts that are corrosively "frozen" or over-torqued. [1] The direction can also be reversed for situations where screws have to be tightened with torque greater than a screwdriver can reasonably provide.
Bleed screw key Bleed screw key in use at a domestic radiator. On a home radiator unit, the bleed screw can be opened, usually by means of a key, to allow unwanted air to escape from the unit. Bleed screws are also found on some pump types fulfilling a similar purpose. They are most often located at the top of the radiator on the side of the ...

Due to the potential problems associated with a cheater bar or snipe, some situations may require an alternative to loosening and removing threaded pipe, screws, bolts or other fasteners. Hydraulic Chain Pipe Wrench – A hydraulic driven wrench which will safely remove threaded pipe from other threaded coupling, valve, etc. while the other ...
