Tension pins are mechanical fasteners that connect and secure two or more parts of a machine relative to each other. They have a body diameter larger than the whole diameter. The spring action of the pin allows it to compress as it assumes the diameter of the drilled hole.

• Tension pins feature a slot on the side that makes it easier to insert and then compress the pin in a drilled hole
• Self-retaining fasteners
• Tension pins resist loosening by vibration
• Made of high-strength steel
