Brass Fasteners

Brass is a general term for a set of copper-zinc alloys that may include additional metals such as lead. Different types of brass have different properties, but all brass is strong, machinable, tough, conductive, and corrosion resistant. This along with beauty and ease of production make brass one of the most widely used alloys.

One of the first commercial uses of brass fasteners was on naval ships. Another common usage of the metal comes from its non-magnetic nature. For decades brass screws have been used on marine equipment, as these are the best screws for the job. The water resistant and anti-corrosive characteristics of these screws are perfect for use around the sea and underwater.

Copper-zinc alloy brass fasteners are non-magnetic, provide excellent ant-corrosive properties, and are often used in marine and sea water applications.

Wink offers fasteners made from non-corrosive metals including brass. We stock numerous parts in corrosion resistant metals that others simply do not.

We can supply brass fasteners to ASME or ASTM specifications, fasteners made to print, and metric DIN nuts, bolts and screws.

At Wink, the 2 primary standards reference books are the latest editions of IFI Inch Fastener Standards and the ASTM Standards for Mechanical Fasteners. 

Our range of brass fasteners include brass hex cap screws, brass hex bolts, brass oval woodscrews, brass oval machine screws, brass hex nuts, and brass button socket cap screws.

Manufacturing of Brass Fasteners

The three steps in brass screw manufacturing are heading, thread rolling and coating. Thin screws are made from wires and the thicker ones are made from round bar stock. To make the screw, this raw material is cut into the desired size. At this stage it is known as blank.

The blanks then go through a cold working process or cold headed as it is more commonly known. The desired types of drives are pressed into the screw head.

The drive pattern is important because it the head will be classified on the basis of this. It determines the drive type of the screw (or the type of screwdriver it will require). The shape of the head is also equally important. It can be flat, rounded or polygonal. This again influences the drive of the screw.

The efficiency of production is dictated by the heading of the screw in the manufacturing process. Some screw heads require less effort and less waste. A simple flat head will require flat dies, some shapes may require two heading processes. Slotted heads will also need slotting machine.

The screw is still a blank. It requires polish and proper threading of the shank. This is done by thread rolling or cutting. There could be further polishing to removing any waste metal and smoothen the surfaces. Even a small irregularity can jeopardize its functioning.

Some brass screws may also need coating. This is done to add to the properties of the screw making material. For instance, plastic coating can be added for electrical insulation.
