  Details:
Knurled thumb screw brass captive metric coarse machine threaded

Knurled thumb screw used in applications where a fastener is frequently adjusted with easy-grip textured head that allows adjusting and installation to be done simply by hand. Machine screws have a uniform diameter the entire length of the shaft as opposed to tapered screws which have a pointed tip. They are used to fasten machine components, appliances and more. Ever Hardware provides custom made knurled thumb screw and customizable packaging.

Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
By comparison, bronze is principally an alloy of copper and tin. However, bronze and brass may also include small proportions of a range of other elements including arsenic, phosphorus, aluminium, manganese, and silicon. The term is also applied to a variety of brasses, and the distinction is largely historical. Modern practice in museums and archaeology increasingly avoids both terms for historical objects in favour of the all-embracing “copper alloy”.
Brass is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; and extensively in brass musical instruments such as horns and bells where a combination of high workability (historically with hand tools) and durability is desired. It is also used in zippers. Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials.
