Product Details
Color Zinc Plated Carbon Steel Anchor Bolts & Hexagon Flange Nuts
for Industrial Applications
1.Products Details:
Anchor bolts serve as the "root" of the fastening system: made from
high-quality carbon steel (typically grades like Q235 or 4.8/8.8
for enhanced strength), they feature a threaded upper section (for
nut attachment) and a non-threaded lower section (designed to embed
deeply into base materials via grouting, expansion, or chemical
bonding). The matching hexagon flange nuts—also crafted from carbon
steel—boast an integrated flange (a wide, flat circular collar)
beneath the hexagonal nut body, eliminating the need for separate
washers.
Both components undergo color zinc plating (a surface treatment that deposits a zinc alloy layer with a
vibrant, corrosion-resistant finish, often in shades of blue,
purple, or iridescent gray). This system is widely used in
construction (e.g., securing steel frames, columns), infrastructure
(e.g., highway guardrails, bridge components), and industrial
settings (e.g., fixing machinery, electrical enclosures), where
reliability, load-bearing capacity, and resistance to environmental
wear are critical.
2.Key Features:
- The base material—carbon steel—delivers excellent tensile strength and shear resistance, enabling the system to withstand heavy static loads (e.g.,
building structural weight) and dynamic forces (e.g., vibration
from machinery).
- For demanding applications, bolts may be heat-treated to meet
industry strength grades (e.g., 8.8-grade bolts, which can
withstand a minimum tensile strength of 800 MPa), ensuring
long-term structural stability without deformation or breakage.
- Color zinc plating forms a dense, adherent zinc alloy film on the
surface of the bolts and nuts. This film acts as a physical
barrier, isolating the carbon steel from moisture, oxygen, salt
spray, and industrial fumes—common causes of rust and oxidation.
- Compared to standard clear zinc plating, color zinc plating offers 30–50% better corrosion resistance (tested via neutral salt spray tests, often lasting 48–72 hours
without red rust). This makes the system suitable for indoor humid
environments (e.g., factories, basements) and mild outdoor settings
(e.g., covered parking structures).
- The colorful finish also provides visual clarity: it helps workers
identify installed fasteners easily and check for damage (e.g.,
chipped plating) during inspections.
- The integrated flange on the nut replaces traditional flat washers,
saving installation time and reducing the risk of missing parts.
The flange’s wide bearing surface distributes clamping force evenly
across the workpiece, preventing damage to soft materials (e.g.,
painted steel) and reducing the chance of the nut loosening due to
vibration.
- The hexagonal nut shape is compatible with standard wrenches and
socket tools, allowing for quick, secure tightening—even in tight
spaces where power tools may be hard to maneuver.
- Anchor bolts are designed to create a permanent bond with base
materials:
- Expansion anchor bolts: Feature a cone-shaped sleeve that expands when the bolt is
tightened, gripping the concrete tightly.
- Chemical anchor bolts: Use epoxy resin to bond the bolt to the drilled hole, ensuring
uniform load distribution and resistance to pull-out.
- This secure anchoring prevents shifting or detachment of heavy
structures, even under extreme conditions (e.g., strong winds,
seismic activity).
- The system is adaptable to diverse scenarios:
- Construction: Securing steel beams, prefabricated walls, and
concrete formwork.
- Industrial: Fixing heavy machinery (e.g., generators, conveyors) to
factory floors.
- Infrastructure: Installing traffic signs, street lamps, and
guardrails.
- It works with multiple base materials, including concrete, brick,
stone, and thick metal plates.
- Carbon steel is an affordable alternative to stainless steel, while
color zinc plating extends the fasteners’ service life—reducing the
need for frequent replacement and maintenance costs.
- The all-in-one bolt-and-nut design lowers inventory costs (no need
to stock separate washers) and minimizes installation errors (e.g.,
mismatched washer sizes).
