For the reviews saying they won't turn, add some dry lube to the inner gearing, I did this to one that was a bit tough to turn and it works perfectly now. ### ⭐⭐⭐⭐⭐ Practice on scrap wood first. Use carbide hole saw. *by R***A on May 13, 2025* Holds very well. I feel it was worth the price. ### ⭐ terrible product *by N***H on April 22, 2023* The ut would not seat on bolt. Very stiff movement. Would not seat after several attempts. Finally got stuck and would not back off - could not remove - runined $300 section of railing. I also purchase the jig set - that is of no value It does not seat accurately on the end of railing. It does not support the needed drill sizes to for this product. It is critical to align the bore holes and to keep them true, which is very difficult without a jig - and the jig tool that jip bolt sells, again, does not support the bit size needed for this product. ## Frequently Bought Together - Zipbolt 16.610 UT Micro Railbolt – Connect Low Profile Handrails to Staircase Fittings and Newels, Fast, Easy Residential and Commercial Installation, New Construction and Remodels — 1 Double Pack - Zipbolt 11.560 Angled Railbolt — Angled Staircase Handrail to Newel Post Connector for Lower Connection, Residential and Commercial Installation, New Construction and Remodels --- ## 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.tn/products/35451380-zipbolt-ut-micro-railbolt-small-handrail-to-fittings-1-x](https://www.desertcart.tn/products/35451380-zipbolt-ut-micro-railbolt-small-handrail-to-fittings-1-x) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-04*
