6 Lobe Pin TX Socket Cap Thread Rolling Screws (DIN 7500 with Pin)

SKU: TH12 Category: Brand:

6 Lobe Pin TX Socket Cap Thread Rolling screws are also referred to as Star Pin Drive screws, Tamper Torx ®, Torx® Pin and Resistorx®, providing a medium level of security and tamper resistance at a relatively low cost.

They host a 6-point star-shaped screw head, with a centre pin, which resists standard torx bits. A special insert bit or key wrench is required to insert and remove it.

The screw offers an economic, secure solution and is able to be used in higher torque applications, meaning it can be tightened to very high levels. Other advantages include reduced slippage when compared to other drives such as Philips and 2-Hole. This reduces the risk of damage to drive tip, screw head or application, making the screw more cost effective.

Thread Rolling screws host a three lobe thread design which when inserted into the fastening material, creates it’s own threads, pushing any excess material into the relief areas of the screw. This increases resistance to vibration and reduces the chance of the screw becoming loose.

They are typically designed for use with metals, but can be suitable for use with other malleable materials. These screws also help to avoid loose chips that are caused by other thread cutting processes.

6 Lobe Pin TX Socket Cap Thread Rolling screws can be driven into a pre-drilled hole without the need for thread tapping, however an extruded hole may provide extra length and allow for improved retention.

They are manufactured from Steel Zinc Plated and Steel Black Plated as standard.

Available from Fastenright with thread sizes from M4 to M6 and lengths ranging from 10mm to 30mm.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
