A steel fastener is a piece of hardware that mechanically connects or attaches two or more things. Fasteners are commonly employed to construct non-permanent junctions, which can be removed or dismantled without causing damage to the connected components.

2. TYPES OF FASTENERS
• ASTM A193 Gr.B16 / A194 Grade 7
Fasteners
• ASTM A193 Gr.B7 / A194 Grade 2H
Fasteners
• Super Duplex Stainless Steel 32750
(F53) Fasteners

3. ALLOY STEEL B7-2H FASTENERS
ASTM A194 Grade 2H is a specification for
high-tensile carbon steel nuts and other
internally threaded fasteners. Hot forging,
cold forging, or machining from heat
treated bar material are all options for
producing Grade 2H nuts.

4. SUPER DUPLEX STEEL S32750 FASTENERS
Super Duplex Steel S32750 Fasteners is a super
duplex stainless steel with a greater alloy
composition, making it stronger and more
corrosion resistant than Duplex 2205. The saw
processing of Super Duplex Steel S32750 Nuts is
a mechanical procedure that results in enhanced
hardness for the current structure and
substantially less unwanted deformation.

5. ALLOY STEEL B16, GR 7 FASTENERS
Only high-quality raw materials purchased from
reputable market suppliers are used to
manufacture the fasteners. Fasteners are also
made from high-quality alloys in accordance with
industry standards such as ASTM, ASME, and
others.
High strength, robust design, anti-corrosive, great
tensile strength, and high durability are some of
these features.
