1/2"X7" A2 A4 Stainless Steel Hex Cap Screw Super Long Hex Bolt
1. Product Description
Stainless steel,an iron based material with a minimum of 10.5% chromium. This
material is known for its corrosion resistance and has vdiffer
strengths depending on the amount of chromium and nickel alloy. The
chromium forms a protective layer when exposed to oxygen, keeping
the steel underneath from corroding. There are over 150 grades of
this material with the 304 and 316 series being the most common.
Stainless Steel often refers to steel with resistance to air, water, acid, alkali
salt or other medium corrosion. According to the different
composition of the alloy, respectively, focusing on stainless steel
and acid resistance. Some steel, although with a stainless steel,
but not necessarily acid, acid-resistant steel is usually a
stainless steel. For the production of fasteners are mainly
austenitic stainless steel, in people's daily life, often referred
to as stainless steel is also austenitic stainless steel. We use
the stainless steel fasteners, raw materials are mainly used
austenitic 302,304,316 and "low nickel" 201 and so on.
A hex cap screw is a threaded fastener with a hexagonal-shaped head. While the term
hex head screw is generally used interchangeably with hex bolt,
these two fasteners are actually very different. Hex screws are
typically smaller than hex bolts, but this is not always the case.
A hex cap screw can be significantly larger than a hex bolt
depending on the applications, so it's important for users to learn
the identifying features of each in order to choose the correct
fastener for each job.

These screws are usually used in a variety of manufacturing and
industrial applications. They are used to join wood, metal, and
composite materials. Typically, hex screws are used in projects
where precision is valued above strength and mechanical
performance. With no nut required, they can be used in smaller
areas where a hex bolt would not fit easily. Hex bolts are
generally reserved for construction purposes, such as joining wood
or metal beams.
Also they are used in these area: Environmental protection
equipment, medical equipment, communications equipment, power
facilities, electronic products, food machinery, petrochemicals,
ship assembly, valve pipelines, curtain walls, open space
