Impact Socket Wall Reduction

Mark (our oldest son) required an impact socket reduced in wall size from 20.85mm to 18mm for a specific work related job he does. It also had to be made to reach deeper so removal of a step area was done also.

Being a wet day out side I closed the garage door and had a go, being an Impact socket it has a thicker wall and heat treatment gives impact sockets a black colour as well s hardens them more.

Impact Sockets

Many applications use air driven or electric impact wrench or impact driver to deliver the amount of shock and torque required to tighten or loosen the different bolts or nuts in use. Inside an impact wrench there is a rotating hammer, usually driven by electricity or air pressure, that is used to incrementally rotate their output shaft. The impact wrench is designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft. Some impact wrenches can deliver over 600 ft-lb (815 Nm) of torque which is enough to break many common fasteners. Even if the socket, attached to the impact wrench, does not turn it is hit with successive hammer blows by the impact wrench's internal hammer. These successive blows are often enough to loosen or tighten a tight or corroded nut or bolt or in some cases break or strip the fastener. Impact wrenches are hard on the sockets since the sockets in use also get hammered. Regular chrome plated "hand sockets" like those commonly included with hand ratchet wrench tool sets are not suitable for this kind of high load impact application. Hand sockets, when used with an impact wrench, can break or shatter explosively if they are used with an impact wrench. Impact sockets are specifically designed and manufactured for impact gun use, and are nearly always made from a thicker, tougher and more ductile alloy steel that is then heat treated for extra durability. Most impact sockets made for "standard" hexagonal fasteners have a six point design. For more flexibility many impact sockets are made with swivel type socket—socket wrench attachment geometry. These impact sockets are rarely, if ever, chrome-plated, as chrome will chip off under impact use, and the process of chrome plating causes some hydrogen embrittlement which slightly weakens "standard" chrome plated sockets. Instead, impact sockets are most commonly finished with a black oxide surface or other coating to provide corrosion and rust protection and improved appearance even after hard impact wrench use. Although ordinary hand sockets should never be used with impact wrenches, impact sockets can be used with hand socket wrenches and other hand drivers. Though in cases of extreme force they may fail at a lower torque rate due to their more ductile qualities.





 Left;- Socket prior reduction its a 12mm hex. Max point width internal is 14mm.

Right:- Using the Carbide tool as the HSS wouldn't cut.

This possibly needs heat treatment again I am checking on that.

Metals

  • Standard sockets are typically constructed of polished Chrome Vanadium steel. This type of tool provides qualities such as resistance to flexing and a lack of porosity, which allows you to easily clean the sockets and naturally resist rust.Manufacturers construct impact sockets of hot forged Chrome Vanadium steel with a significantly thicker socket wall. Not only does this heat treatment produce a harder surface, it also imparts a darker coloration to the metal, which helps you distinguish impact sockets from standard sockets in the tool box. The thicker socket wall provides additional socket strength to the tool, helping to prevent cracks from forming in the thinnest areas of the socket wall.
