I’ve kept these though for the off chance I need a replacement and this could be even just a temporary solution. My M6’s work very well for allowing me to disassemble my electric scooter and access the battery. ### ⭐ 1.0 out of 5 stars Read carefully, description can be deceiving *by A***R on Reviewed in the United States on July 7, 2020* Make sure to read the description carefully and look at the photos carefully. The kit does not come with matching wing nuts for each size of thumb screw. In fact, there are two sizes of wing nuts that fit none of the thumb screws provided. The large thumbs screws, which I needed, have no matching wing nuts that come with the kit. --- ## 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.co.th/products/110841616-lby-80pcs-knurled-hand-screw-m4-flat-knurled-head-fully](https://www.desertcart.co.th/products/110841616-lby-80pcs-knurled-hand-screw-m4-flat-knurled-head-fully) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-14*
