Stump Swagebolts (“S”) are a specialized type of swage fastener engineered for demanding applications where strength, reliability, and ease of installation are essential. Unlike conventional swagebolts, Stump Pins are manufactured without a shear-off pintail. This makes them particularly effective in situations where a flush and clean finish is required, or where the pintail could interfere with surrounding components.

Manufactured from high-strength steel, these fasteners are available in 16 mm, 19 mm, and 22 mm sizes, providing flexibility for a wide range of structural and industrial applications. Installation is achieved using the dedicated T109 installation tool, which swages the collar securely onto the pin, creating a vibration-resistant joint with excellent clamping force.

Because of their robust design and streamlined installation, Stump Swagebolts are widely used across industries such as mining, construction, and heavy machinery manufacturing, where durability and performance are critical. They deliver consistent strength while reducing installation time and ensuring long-term reliability in harsh operating conditions.
