Carbon Steel

Carbon steel screws are the most widely used and cost-effective fasteners, offering an optimal balance of strength, durability, and value for a vast range of general-purpose applications. Their performance is primarily defined by the carbon content and subsequent heat treatment, which allows for a spectrum of strength grades to meet different mechanical demands.

Product details

Typical Applications:

General Manufacturing & Assembly: Used extensively in machinery, equipment, and product assembly where high strength and good wear resistance are required.
Construction & Infrastructure: Suitable for structural framing, steel-to-steel connections, and securing building materials, often after protective coating.
Automotive & Industrial Components: Employed in non-critical interior parts, brackets, and assemblies, especially in medium to high-strength grades.

Our Product & Custom Capabilities:
We supply carbon steel screws in a full range of grades and configurations, with comprehensive customization to meet specific needs:

Material Grades: From low-carbon steel (e.g., SAE 1008/1010) for general use to medium/high-carbon steel (e.g., SAE 1035, 1045) and alloy steel (e.g., SCr435) for high-strength requirements, complying with standards like ASTM and ISO.
Strength Classes: Standard offerings include Grade 4.8, 8.8, 10.9, and 12.9, achieved through controlled heat treatment processes such as quenching and tempering.
Surface Treatments: A wide selection of coatings is available for corrosion protection and appearance, including zinc plating (blue/white/yellow), black oxide, phosphate, and geometric corrosion resistance coatings.

Our carbon steel screws provide reliable, high-performance fastening solutions, engineered to deliver specified mechanical properties and long-term service life in diverse industrial environments.
