Next: 6 Lobe Pin TX Security Grub Screw Cup Point 
Prev: Pin Hex Security Grub Screw Dog Point (DIN 915 with Pin) 
Pin Hex Security Grub Screws Flat Point, created to DIN 913 standard (ISO 4026) with a pin, are tamper-resistant fixings that require a special driver bit or key to fasten or remove, meaning more conventional driver bits or Allen keys will not work.
The Flat Point reduces the damage caused to the shaft and is mainly used when regular adjustment is needed. The flat nature also means that it will align well against ground flats, and can also be used against a thin wall or soft material.
These tamper-proof set screws are suitable for higher torque applications and the Pin Hex drive makes it ideal for situations requiring medium security and where the fixing needs to be removed for maintenance.
They provide a range of advantages, one of which is that they are designed to reduce cam-out, something that often occurs in Phillips and 2-Hole drives. This helps to reduce the risk of damaging the drive tip, screw head, or application, and the hex drive allows for better torque compared to conventional screw heads.
These security grub screws, which provide a medium security resistance for a relatively low cost, can be referred to by a variety of different names that include Hex Pin Grub Screws or Hex Pin Set Screws.
Made from both A2 and A4 Stainless Steel. Available from Fastenright with sizes from M1.6 to M20 and lengths from 2mm to 190mm. Pin Hex Security Drill Bit is also available at Fastenright.
Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
