Every size allen wrench you'ever need. Seems to be quite durable, too. Simple enough to bring the whole pack to where you need to do the work. Plus a filing system with labels. ### ⭐⭐⭐⭐⭐ Good purchase *by D***N on May 18, 2026* Very good Allen Wrenchs. I am happy with my purchase. I would order again. ### ⭐⭐⭐⭐⭐ Great set!! *by A***N on May 15, 2021* I got tired of my son taking all the tools out of the toolbox and losing them that I bought this set for him for Christmas and also for me as a replacement for the ones lost. We’ve both had this hex wrench set for quite a while. It has been a lifesaver so many times! It’s amazing how many different kinds of furniture, chairs etc need to be assembled with hex wrenches. Just this morning I had to use this set again—this time needed the metric ones. This set has every size you would ever need, and they are always very neatly in order, so it’s easy to tell if one is missing! I highly recommend this set. I write honest reviews to help others make informed purchases. I do that because I read reviews myself and appreciate how helpful they can be. I hope my review helped you. ## Frequently Bought Together - YIYITOOLS - HN-1-001 Hex Key Allen Wrench Set – 30-Piece Industrial Grade Set Tools, 1/20-3/8 inches, 1.27-10 mm, Black and Silver - EKLIND 10111 Hex-L Key allen wrench - 11pc set SAE Inch Sizes .050-1/4 Short series - Amartisan 10-Piece Magnetic Screwdrivers Set, 5 Phillips and 5 Slotted Tips Professional Cushion Grip Screwdriver Set --- ## 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.us/products/215185937-yiyitools-hn-1-001-hex-key-allen-wrench-set-30](https://www.desertcart.us/products/215185937-yiyitools-hn-1-001-hex-key-allen-wrench-set-30) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-08*
