Toolcraft C137053 spring pins, also known as tension pins or roll pins, have dimensions of 20 mm in diameter and 75 mm in length. These precision-crafted pins are made from high-quality spring steel, offering excellent elasticity and mechanical strength for secure fastening applications. The spring steel construction ensures reliable performance under vibration and load conditions while maintaining consistent clamping force over an extended period of use. Each pack contains 25 pieces, making this solution economical for maintenance, repair, and assembly work. These pins are designed for use in machinery, equipment assembly, and industrial applications where secure yet removable fastening is required. The slotted tube design allows for easy installation into drilled holes, compressing the pin upon insertion and then expanding to create a tight, secure fit. The 20 mm diameter provides significant holding power, while the 75 mm length accommodates various material thicknesses. Spring pins have the advantage of being reusable in many applications, allowing for disassembly and reassembly without significant loss of performance. The Toolcraft brand ensures consistent quality and dimensional accuracy, with each pin meeting industrial standards for spring pin fastenings. These pins are suitable for use in automotive, manufacturing, and equipment maintenance applications where vibration resistance and reliable fastening are essential requirements.
