For 3506 Metric Threaded Slotted Self-Tapping Inserts
The slotted type driver can be used with the Yardley slotted TRISERT inserts. The two tangs located under the shoulder engage the slot on the end of the insert. This driver can be used with a number of driving mechanisms. For very low volume it can be chucked into a hand tapper. For moderate quantities it can be chucked into any drill. And for larger quantities it can be used with most tapping heads, drill presses and the Yardely Bench Model Pneumatic Inserter.
