Hex Bolt Carbon Steel Grade 8.8 M12 1/2 Inch Zinc Plated High
Strength Mechanical Applications
Product Description:
This hex bolt, made from carbon steel grade 8.8, offers superior
strength for high-performance mechanical applications. The M12 size
with a 1/2-inch thread allows for precise fastening, making it
suitable for use in heavy machinery, automotive, and construction
applications. The zinc-plated finish enhances the bolt’s corrosion
resistance, ensuring durability even in slightly exposed or humid
conditions. This bolt complies with ASTM A193 and A194 standards,
which guarantees that it can withstand high levels of stress and
pressure in demanding environments. It’s a preferred choice for
industrial settings requiring a reliable fastening solution that
can handle mechanical loads and resist environmental wear.
Applications
1. Carbon steel is divided into several levels
Steel carbon screw performance level 3.6, 4.6, 4.8, 5.6, 6.8, 8.8,
9.8, 10.9, 12.9 and so on more than 10 grades, of which 8.8 level
and above the screw material for the low-carbon alloy steel or
medium-carbon steel and heat-treated (quenched, tempered), commonly
known as high-strength screws, and the rest are commonly known as
ordinary screws. Screw performance level marking has two parts of
the digital composition, respectively, the screw material value of
the nominal tensile strength and flexural strength of the value.
2. Carbon steel strength class
Carbon steel and stainless steel strength difference of 1528 MPa,
steel is the national construction and the realization of the four
indispensable and important materials, its wide range of
applications, a variety of varieties, according to the shape of the
cross-section of the different, steel is generally divided into
profiles, plates, tubes and metal products of the four major
categories, and is divided into heavy rail,
Light rail,
Large section steel,
Medium section steel,
Small section steel,
Steel cold-formed sections
High-quality steel, wire rod, medium-thick steel plate, thin steel
plate, electrical silicon steel sheet, strip steel, seamless steel
pipe steel, welded steel pipe, metal products and other varieties.
