Toolcraft TO-411186 spring pins, also known as roll pins or tension pins, are precision-engineered fastening components designed for reliable mechanical connections. These spring pins measure 20 mm in diameter and 180 mm in length, manufactured from high-quality spring steel for exceptional durability and consistent performance. The product includes 10 pieces per package, providing sufficient quantity for various assembly and repair applications.

Spring pins function through their slotted cylindrical design, which allows compression during insertion and subsequent expansion to create a secure, vibration-resistant fit in drilled holes. This design eliminates the need for additional locking mechanisms while maintaining reliable retention under dynamic loads and temperature variations. The spring steel construction ensures excellent fatigue resistance and maintains clamping force over extended service periods.

These pins are particularly suitable for applications requiring frequent disassembly and reassembly, as they can be removed and reinstalled multiple times without significant performance degradation. The TO-411186 spring pins are compatible with standard 20 mm drilled holes and provide consistent dimensional accuracy for precise fitment. Their corrosion-resistant spring steel composition offers good performance in various environmental conditions.

These components are commonly used in machinery assembly, automotive applications, industrial equipment, and mechanical systems where secure fastening with some flexibility is required. The pins feature a smooth surface finish that facilitates easy installation while maintaining secure holding capability. Each pin undergoes quality control to ensure dimensional consistency and mechanical properties meet industry standards for spring pin applications.
