62350062 - ESAB Roll Pin .188 x .750 Steel Zinc Plated

Industrial Grade Fastening Solution

The ESAB 62350062 Roll Pin is a critical hardware component designed for the maintenance and repair of industrial machinery. Often referred to as a spring pin or slotted pin, this fastener is engineered to secure two or more machine parts together with a high degree of reliability. Measuring 0.188 inches in diameter and 0.750 inches in length, it fits standard bore sizes associated with these dimensions, providing a tight, vibration-resistant interference fit.

Manufactured from high-grade steel, this pin is built to withstand the shear forces and mechanical stresses typical in heavy-duty environments. The "STLZPC" designation indicates that the steel has undergone a Zinc Plating process. This surface treatment is vital for industrial applications, as it provides a protective barrier against oxidation and rust. Whether the equipment operates in humid workshop conditions or is exposed to fluctuating temperatures, the zinc coating ensures the pin maintains its structural integrity over time, preventing seizure or premature failure.

Mechanism of Action

Roll pins function by compressing as they are driven into a hole that is slightly smaller than the pin's uncompressed diameter. The slot running the length of the pin allows it to flex, exerting continuous radial force against the hole walls. This self-locking mechanism eliminates the need for threading or secondary retention methods like cotter pins, making it an efficient and secure solution for assembly pivots, gear retention, and linkage connections.

Application Versatility

While specifically cataloged as an ESAB spare part, the standardized dimensions of this roll pin make it a versatile component for any maintenance, repair, and operations (MRO) inventory. It is suitable for use in a wide array of mechanical assemblies where a 3/16-inch (0.188") pin is required. Its robust construction ensures it can handle the dynamic loads found in power transmission systems, automated feeders, and manual tools.
