The Taptite® thread-rolling screw produces strong threads in drilled, punched, or cored holes. The Trilobular™ shape provides for low drive torque, a high strip to drive ratio and excellent resistance to vibration. Availability: Replaced by Taptite II®.

Suggested hole sizes for TAPTITE II®, DUO-TAPTITE® and TAPTITE® CA Screws and Bolts at various percentages of thread engagement EXAMPLE – The shaded area indicates that an M5 – 0.8 screw size in a 4.58 hole size provides 80% thread engagement.

The Duo-Taptite® thread-rolling screw has a generous lobulous lead for easy entry and optimum forming action and less lobulation in the body of the fastener for increased holding power. The design provides for easy entry, positive alignment, and consistent starting stability along with a higher strip to drive ratio, higher prevailing torque ...
