MATERIAL GRADE

 

CARBON STEEL :

 

Carbon steel provides strength, affordability, and versatility, making it ideal for construction,

automotive, and general-purpose fasteners that require moderate durability.

Grades offered: 4.6 & 5.6

 

ALLOY STEEL :

 

Alloy steel enhances toughness, strength, and wear resistance, making it ideal for heavy-duty

machinery, construction, and industrial applications.

Grades offered: 8.8, 10.9 & 12.9

 

STAINLESS STEEL :

 

Stainless steel is resistant to corrosion and highly durable, making it ideal for outdoor, marine,

and high-moisture environments, such as the medical and food processing industries.

Grades offered: A2-70 (304), A4-70 (316), A4-80 (316), SS – 310

Coating

Coating is an essential process that enhances durability, corrosion resistance and performance. Below are the types we offer:

  1. Electroplating: In this process, a metallic coating is deposited onto fasteners, enhancing corrosion resistance, durability, and aesthetic appeal.
  • Zinc Plating – this method provides corrosion resistance and a smooth finish, ideal for fasteners used in automotive and construction industries.
  • Cadmium Plating – This enhances durability and appearance, commonly used in decorative and industrial applications.
2. Hot-Dip Galvanizing: In this process, a thick zinc coating is applied for superior corrosion protection, making it suitable for outdoor and heavy-duty applications.

Heat Treatment

Heat treatment is a controlled process that enhances fasteners’ strength, hardness, and durability through precise heating and cooling.

Quenching & Tempering: Quenching cools heated metal to harden it, while tempering reduces brittleness and enhances toughness, improving overall strength.

Case Hardening: Case hardening strengthens a metal’s outer surface while preserving a softer, ductile core to enhance wear resistance and toughness.

Annealing: Annealing is the process of heating metal and then allowing it to cool slowly. This technique softens the metal, improves its machinability, and relieves internal stresses.
