 L-type wrench

1)Material

Stainless steel 18-8

An alloy of steel with high corrosion resistance.

Zinc plated grade 2 steel

A low carbon steel for general use. Zinc plated for moderate corrosion resistance.

Zinc plated grade 5 steel

A tempered medium carbon steel. Grade 5 falls between grade 2 and grade 8 in strength, and is commonly found in automotive applications. Zinc plated for moderate corrosion resistance.

Zinc plated grade 8 steel yellow

A tempered medium carbon steel. Grade 8 is stronger than grade 5, and is commonly found in high strength automotive applications. Zinc plated for moderate corrosion resistance.

Grade 8 steel plain finish

A tempered medium carbon steel. Grade 8 is stronger than grade 5, and is commonly found in high strength automotive applications. Unplated finish.

Chrome plated grade 5 steel

A tempered medium carbon steel. Grade 5 falls between grade 2 and grade 8 in strength, and is commonly found in automotive applications. Chrome plated and polished for a mirror like finish.

Hot dipped galvanized steel

A low carbon steel for general use. Hot dipped galvanized (A153) for very good corrosion resistance.

3)Features

Some features of hex keys are:

The tool is simple, small and light.The contact surfaces of the screw or bolt are protected from external damage.There are six contact surfaces between bolt and driver.The tool can be used with a headless screw.The screw can be inserted into its hole using the key.Torque is constrained by the length and thickness of the key.Very small bolt heads can be accommodated.The tool can be manufactured very cheaply, so one is often included with products requiring end-user assembly.Either end of the tool can be used to take advantage of reach or torque.The tool is L-shaped

4.) Manufacturing methods

Hex socket screw heads are usually made by stamping the head with a die, plasticly deforming the metal. Other ways to generate the hex socket include linear broaching and rotary broaching. Broaching the heads with a linear broach is essentially the metalworking analog of mortising wood with a mortising machine; a hole is drilled and then the corners are broached out. This operation often leaves little telltale curled chips still attached at the bottom of the socket. These are negligible for most applications.Hex keys are made by imparting the hexagon cross-section to steel wire (for example, with a die), then bending and shearing.
