    • Check Dimensions...
Size: D20 L25 Style: 5x8mm
EDIT: Seller reached out after the review below and sent a replacement set. The new ones are far more accurate (within .02mm), I have not installed them onto a printer yet, as I had already found an alternate in the meantime, but they seem to be well made, and secure to the motor shaft and threaded rod snugly. Not sure if I got ones that were just mislabeled, or what the issue was with the first set. But the replacements are perfectly adequate. ORIGINAL REVIEW: Horrible accuracy. Ordered the 5mm to 8mm couplers for my printer. These measured 4.12 mm inside diameter on what was suppose to be the 5mm side and 9.96 mm on what was supposed to be the 8mm side. They don’t even come close to fitting, being off dimensional accuracy by as much as 24.5%. Avoid these particular couplers. ... show more

    • These are not made properly.
Size: D20 L25 Style: 5x8mm
These have no give and are very solid in transferring wobble. The inside shaft tolerances are off by a lot and are really loose so you have to tighten them extremely tight to grip but by that point geometrically you are pushing the shafts off center and creating more wobble than you had before.

    • Wobbles like crazy
Size: D20 L25 Style: 5x8mm
The boreholes are not straight. These actually introduce more wobble than they fix. By itself sitting in the motor shaft, they are already off-centered. Once you attach the lead screw, the effect becomes even more apparent. Save your money and avoid these. Buy disc couplers/diagram couplers instead. Or fork out the money and buy real spider couplers. ... show more
