NB16B Spur Gear, 14.5 Pressure Angle, Steel, Inch, 16 Pitch, 0.500" Bore, 1.125" OD, 0.500" Face Width, 16 Teeth

Quality product at a decent price and extremely fast shipping. Does not have a keyway or a set screw BUT you also don't have to have either. If you know how to drill a hole then you are in luck. Just drill a hole where you want a set screw and also through the shaft you are mounting this to. Then install a spring pin through the gear and shaft. That will handle more torque then a screw and keep the gear in place. No need to weld it

I have a metal lathe that needed this gear size. After modifying the gear it works great

The overall dimensions were perfect, missing locking screw.

Product deserves a 5 star review, but it's zero star description lowered it to 3 stars. The images indicate both a keyway, and a set screw. This item has neither.If you want just the set screw try http://www.amazon.com/gp/product/B004BDO36O/ref=oh_details_o03_s05_i00?ie=UTF8&psc=1.They need to get this right, as we have no time to return these & have to do our own labor to make it happen.

I do not know now.

make sure you review the cad drawing before ordering and don't just go by the pretty picture

Don't believe the pictures or description. No keyway. No set screw. Had to manually drill and tap my own set screen holes.This is only for press on use.

Very high quality. good price quick shipping.
