TAP-R THREAD ROLLING SCREWS

Tap/R fasteners use a shank in the graduated thread rolling area to roll their own perfect mating threads in an un-threaded pilot hole. The tapered point of these thread roll forming fasteners easily locates the pilot hole and eliminates cross-threading in existing holes. The partial threads on the shank form threads in the whole during the initial drive. Full threads complete the screw and provide perfect engagement to finish the drive.

Advantages:

These thread rolling screws provide a number of advantages, including:

• REDUCE DRIVING TORQUE and increase stripping torque.
• ROUND SHANK ASSURES FULL 360° THREAD ENGAGEMENT for maximum holding power.
• RETAIN MORE APPLIED TORQUE AND CLAMP LOAD than tri-lobular type screws.
• RETAIN SAME HOLE SIZES as trilobular type screws. No need to change specifications or tooling.
• RAPIDLY LOCATE HOLES. Unthreaded relief area on point quickly positions screws in pilot holes.
• REUSABLE IN SAME HOLE WITHOUT CROSS THREADING. With its unique tapered, intermittent thread form, the TAP/R screw can be removed and reused in the same hole, time after time without damaging the mating thread.
• REMOVES PAINT AND PORCELAIN FROM HOLE. The relief areas on the two sides of the shank function as a paint scraper to remove paint or porcelain from the pilot hole.
• RELIABLE. CONSISTENT PERFORMANCE makes TAP/R screws ideal for automation qualified applications.
