A basic guide on fasteners

• 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.

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

 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.

 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.

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.
• Chemical Composition of alloy steel B16
