Simple, robust, fits the seat tube perfectly ### ⭐⭐⭐⭐⭐ Quality Steel, excellent fastener. *by B***R on August 22, 2022* My Bike frame's seat post has been secured with a standard nut and bolt for a number of years, but as I was repainting and updating it to modern components, i wanted to get the appropriate hardware for my seat-tube. This seat post binder bolt is an absolutely perfect fit for my 70's steel tube frame, and sits in the seatpost flanges exactly as it is intended to. holds securely, and has not loosened. Things to note that are not specified in the item description: -This binder bolt has BOTH a threaded nut, and a threaded bolt. It was easy to assume this was the case, but the photos do not show that it is in fact a nut and bolt that come together as a seamless junction when fully threaded. The threaded nut side has an external flange on the interior face of the head. This piece is intended to fit in the notch that should be present on your bike; it's purpose is to hold the nut in place so the bolt side can be fastened from one side and not spin when tight. If you do not have a notch, you would need to cut one, or use a different style of fastener. I have a notch, and this bolt allowed be to realize what it was for. Overall, quality metal, smooth threads, and a perfect fit on a 70's road bike with a 25.4mm ID seatpost frame. ## Frequently Bought Together - ONIPAX Seatpost Binder Bolt Screw - Origin8 Pro-Fit Alloy Seat Post - Kalloy Uno 602 350mm Alloy Seatpost --- ## 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.it/products/382977042-onipax-seatpost-binder-bolt-screw-1-pcs](https://www.desertcart.it/products/382977042-onipax-seatpost-binder-bolt-screw-1-pcs) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-16*
