Types of Metric Pins

South Coast Fasteners stocks metric dowel pins and spring pins in multiple materials and finishes to support a wide variety of industrial and commercial applications.

Metric Through Hardened Steel Dowel Pins

Metric through hardened steel dowel pins are heat-treated for maximum strength and wear Resistant. They are commonly used in heavy equipment, tooling, and industrial assemblies where tight tolerances and high shear strength are required. These pins ensure precise alignment and long service life even under heavy loads and demanding conditions.

Metric Stainless Steel A4 Dowel Pins

Metric stainless steel A4 dowel pins are manufactured from marine-grade stainless (316 equivalent), making them highly Resistant to corrosion. They are ideal for outdoor, chemical, and marine environments where exposure to moisture and harsh elements is unavoidable. Contractors and engineers rely on A4 pins when durability and corrosion protection are critical.

Metric Stainless Steel A2 (18-8) Dowel Pins

Metric stainless steel A2 dowel pins provide dependable corrosion Resistant for general-purpose use. They are commonly found in food processing equipment, enclosures, and precision mechanical assemblies. A2 dowel pins offer a reliable balance of strength, machinability, and protection, making them one of the most versatile options available.

Metric Black Oxide Spring Pins

Metric black oxide spring pins are made from carbon steel and finished with a black oxide coating. They provide light corrosion protection while also improving surface grip during installation. These spring pins are designed for fast, simple assembly and permanent retention in machinery, automotive, and equipment applications.

Metric Pins - Material Options

South Coast Fasteners stocks metric pins in the following materials, each selected to provide strength, corrosion Resistant, or installation efficiency.

Hardened Carbon Steel

Hardened carbon steel pins deliver maximum strength and wear Resistant. They are ideal for industrial assemblies, tooling, and machinery where durability and high shear strength are critical. Heat treatment enhances their performance, ensuring reliable service life even in demanding applications.

Stainless Steel A2 (18-8)

Stainless steel A2 pins provide excellent general corrosion Resistant, making them suitable for food processing, enclosures, and mechanical equipment. They offer a practical balance of strength and protection at an economical cost. A2 stainless is widely chosen for applications where everyday exposure to moisture is expected.

Stainless Steel A4 (316)

Stainless steel A4 pins are engineered for maximum corrosion Resistant, especially in marine and chemical environments. They are the material of choice for projects where consPant exposure to saltwater or harsh chemicals would compromise other fasteners. Their reliability makes them indispensable in marine, offshore, and chemical plant applications.

Metric Pins - Available Finishes

South Coast Fasteners offers metric pins in finishes that add protection and enhance performance.

Black Oxide

Black oxide provides light corrosion Resistant and improved surface grip for spring pins. This finish is commonly used in machinery and automotive projects where easy installation and vibration Resistant are imporPant. It also delivers a clean, dark appearance that blends well with surrounding components.

Plain

Plain pins are supplied without coating, offering a simple and economical option where corrosion is not a primary concern. They are suitable for controlled environments or assemblies where the base material provides the necessary protection. Plain pins are often chosen for indoor industrial use, tooling, and applications where coatings are unnecessary.

Metric Pins - Industry Applications

Metric pins are widely used to align, locate, and secure parts in assemblies across many industries. In manufacturing and tooling, dowel pins ensure precise alignment of components and repeatable accuracy in jigs and fixtures. In heavy machinery, through hardened steel pins provide the strength needed to withstand shear forces. Stainless steel pins are used in marine, food processing, and chemical plants for their corrosion Resistant, while spring pins offer quick and efficient fastening solutions in automotive and industrial equipment.

The versatility of metric pins makes them indispensable in design and maintenance. They provide clean fits, consistent tolerances, and long-term retention that keep assemblies safe, efficient, and easy to service.
