McMaster-Carr Type A Groove Pin GA1871000G2ZN, Zinc-Plated Steel, 0.187" x 1.000" (Pack of 10)

The McMaster-Carr Type A Groove Pin GA1871000G2ZN is a precision-engineered fastener designed for secure, vibration-resistant assembly in industrial applications. Made from zinc-plated steel, these pins feature three longitudinal grooves that expand slightly when driven into a hole, providing a tight fit without the need for threads or additional hardware. Each pin measures 0.187 inches in diameter and 1.000 inch in length, making them ideal for aligning parts, securing components in machinery, or acting as pivots in mechanical assemblies. Commonly used in automotive, aerospace, and manufacturing sectors, they offer excellent corrosion resistance due to the zinc plating, extending service life in humid or mildly corrosive environments. Advantages include easy installation with a hammer or press, high shear strength, and reusability in some cases. Compared to similar products like clevis pins or roll pins, groove pins provide superior retention without damaging the host material. Drawbacks may include the need for precise hole sizing and potential difficulty in removal without tools. This pack contains 10 pins, appearing new and unused based on packaging and images.
