The threads have a variation every 4mms down the whole part .1mm. .1 mm I know small right? But 50mm later that is huge. Must be a die cut thread with a warn edge in one slot instead of a acme thread head cutter? Very weird error for a acme thread. Also seems deeper in some parts cut. I think this screw was cut with a bad set die or head cutter as the rod was broached. On the other hand! Nut was cut perfectly. And it also was perfectly lose on the screw. I tossed the nut on a old 8t acme I had and it fit nice. So kinda disappointed, the old 8t has less ware then the new one. ### ⭐⭐⭐⭐⭐ Very solid fit and no more backlash *by C***S on Reviewed in the United States on February 23, 2021* I like that this pair of anti-backlash nuts arrives in individual baggies inside of a larger one, especially since I only need the one for now. I have been impressed with the very tight fit between the two halves. This fit is critical since any play between the upper and lower contact flanges will represent the amount of backlash this nut would have. Since the fit is so tight there isn't any perceptible play between the two halves, which is ideal.I used this set to reduce the backlash on my lead screw for my longer lk4 pro. The factory nut was actually pretty good but this eliminates yet one more source of error and variance. I reused the factory mounting hardware so it was a direct replacement and easy swap. ### ⭐⭐⭐⭐⭐ T8 Leadscrew, but packaged well for once *by W***. on Reviewed in the United States on August 25, 2018* There's not much to say about the leadscrew itself, really. It's pretty standard, with an amount of play that's neither exceptional nor remarkably bad, but one thing that I really appreciate: it was actually well packaged and arrived perfectly straight. It was in a box held in the center with foam pieces. 90% of the time I order linear motion parts they come in a plastic bag, or a tube if I'm really lucky, and often they get bowed by this. I had to leave a review out of sheer appreciation for a vendor that actually gives a crap if I receive parts in a usable state. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/57123176-300mm-t8-tr8x8-lead-screw-and-brass-nut-acme-thread](https://www.desertcart.com.cy/products/57123176-300mm-t8-tr8x8-lead-screw-and-brass-nut-acme-thread) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-22*
