Very useful! ### ⭐⭐⭐⭐⭐ A necessity for braze-on equipment installations not intended by the manufacturer. *by A***R on April 6, 2024* The varied thread lengths allow for one-off installations required by the bike owner. High quality bolts. Varied flat washer diameters would be nice a nice addition to the kit. This was the solution for adapting a fork-mount cage to a rear rack application that was not offered by the bike manufacturer. I’m happy. ## Frequently Bought Together - HELIFOUNER 210 Pieces M5 x 6mm /8mm /12mm /16mm /20mm /25mm /30mm, Hex Socket Head Cap Screws Bolts Washers Nuts Kit, 304 Stainless Steel - SHKI 20 Pcs 608 2RS Ball Bearings – Bearing Steel and Double Rubber Sealed Miniature Deep Groove Ball Bearings (8mm x 22mm x 7mm) (608 2RS) - Ktehloy 400Pcs Threaded Inserts, M2 M2.5 M3 M4 M5 M6 Female Thread Metric Knurled Nuts Assortment Kit, Brass Heat Set Insert for Plastic and 3D Printing Components --- ## 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.jp/products/561175353-helifouner-210-pieces-m5-x-6mm-8mm-12mm-16mm-20mm](https://www.desertcart.jp/products/561175353-helifouner-210-pieces-m5-x-6mm-8mm-12mm-16mm-20mm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-22*
