Applications
Pins are versatile fasteners used to align, secure, or join components in mechanical assemblies. Available in various forms—such as dowel pins, cotter pins, clevis pins, and spring pins—they serve distinct functions depending on the application. Whether for temporary positioning or permanent fastening, pin types are chosen based on factors like load capacity, material, precision, and installation ease.
Cotter Pins
Cotter Pins, also known as split pins, are simple yet highly effective mechanical fasteners used to secure bolts, nuts, clevis pins, and other fasteners in place. These pins feature a split, bent-leg design that expands after insertion, preventing unintended loosening in high-vibration or high-load applications. They are widely used in automotive, railway, aerospace, marine, and heavy machinery industries.
At Rajal Industries, we manufacture precision-engineered Cotter Pins conforming to ASME, ISO, and DIN standards, ensuring high-strength retention, corrosion resistance, and long-lasting reliability in demanding industrial applications.
Dowel Pins
Dowel Pins are high-precision cylindrical fasteners used to align, locate, and secure machine components with high positional accuracy. These pins provide exceptional shear strength, wear resistance, and vibration stability, making them ideal for automotive, aerospace, heavy machinery, and precision tooling applications.
At Rajal Industries, we manufacture precision-engineered Dowel Pins conforming to ISO, ASME, and DIN standards, ensuring tight tolerance control, superior load distribution, and long-lasting performance in high-precision assembly applications.
Taper Pins
Taper Pins are cylindrical, slightly tapered fasteners designed for precise alignment, secure positioning, and high-strength fastening in mechanical and structural assemblies. Unlike straight dowel pins, taper pins self-lock into position due to their gradual taper, making them ideal for machinery, tooling, and precision component assemblies.
At Rajal Industries, we manufacture precision-engineered Taper Pins conforming to ASME, ISO, and DIN standards, ensuring superior shear strength, tight tolerances, and long-lasting reliability for industrial, automotive, and aerospace applications.
Spring Pins
Spring Pins, also known as Roll Pins or Slotted Pins, are self-locking cylindrical fasteners designed to absorb shock, vibration, and impact loads while securely holding components in place. These pins feature a slotted or coiled design, allowing compression during insertion and expansion for a tight, interference fit. They are widely used in automotive, machinery, aerospace, and heavy equipment applications.
At Rajal Industries, we manufacture precision-engineered Spring Pins conforming to ASME, ISO, and DIN standards, ensuring high-retention force, fatigue resistance, and long-lasting durability in dynamic industrial environments.
Coiled Pins
Coiled Pins, also known as Spiral Pins or Coiled Spring Pins, are resilient mechanical fasteners designed to absorb shock, reduce vibration, and distribute loads effectively. Unlike slotted spring pins, coiled pins offer superior flexibility and fatigue resistance, making them ideal for high-dynamic load applications in automotive, aerospace, precision machinery, and heavy equipment industries.
At Rajal Industries, we manufacture precision-engineered Coiled Pins conforming to ISO and general industry standards, ensuring high-retention force, long-lasting durability, and superior impact resistance in critical industrial applications.
Quick-Release Pins
Quick-Release Pins are specialized mechanical fasteners designed for fast and tool-free assembly, disassembly, and locking of components in high-precision applications. These pins are commonly used in aerospace, automotive, marine, industrial machinery, and defense applications where rapid engagement and disengagement are required without compromising security.
At Rajal Industries, we manufacture precision-engineered Quick-Release Pins conforming to ASME standards and general quick-release specifications, ensuring high-strength retention, corrosion resistance, and long-lasting performance in dynamic environments.
