The 2GT-3mm Series of belts and pulleys has more aggressive teeth than its little brother the 2GT. 2GT-3mm has the same tooth profile as 2GT, but is with a 3mm pitch instead of 2mm. It is commonly known as GT3. 2GT-3mm is more suited to higher torque applications, making it perfect for your automation projects. These 2GT-3mm Pulley’s have a 6.35mm Bore making a perfect partnership with NEMA23 Stepper Motors

In the case of my motors the bore was too small, however i didn’t use the issue motors but 3 i already had. i had purchased this pully to finally sort out the ongoing problem i was having with an allan key for the pully i had. in the event the grub screw was a size i already had an allan key for, so i drilled out the central hole and now consider the over, somewhat obliquely but sorted.
