Review: works well, get stripped easily have to adjust - I got this to take off the nuts on my used open trailer that were fused on the first one or two worked well but it wasn't actually the product problem it was actually cuz I had very little room on the other side of the trailer underneath to get to the bolts so actually I had to use this product the nut splitter 2 Tac off little by little down to where I could get the nut off, because I was doing this the blade got stripped and wouldn't stay in place but if you just set it manually up against what you want to split it keeps on working and keeps on ticking. * don't get frustrated if this nut splitter keeps slipping off as you use a ratchet. What I did was I cranked it tight on the nut even in a tight space with the nut splitter once it was in grooved in there I went to the other side and if the nut splitter is wedged on the opposite side or you can hold it then you could use a second ratchet on the other side on the fault to loosen it. The problem I was having with the bolt has the nuts were fused on to them so every time I turned the bolt head the nut would spin Review: Fantastic product. - This is a great product for the price, it comes completely apart, so it can be used in many different ways/oiled if need be, my only concern is the internals should slide along a rail to keep the chisel bit vertical in the hole and sometimes the bit Will spin, but otherwise well worth the price. ## Features - NO BOLT DAMAGE: The nut splitter tool splits nuts from 5/16-inch to 7/8-inch across flats with no damage to bolt threads - DURABILITY: The nut splitter features hardened steel cutter - Requires 3/4-inch wrench to operate - Country of origin : China ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R96Z6LY | | Best Sellers Rank | #319,249 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #519 in Nut Drivers | | Brand | CRAFTSMAN | | Color | black, silver | | Compatible Groove Diameter | 1E+1 Millimeters | | Customer Reviews | 4.1 out of 5 stars 850 Reviews | | Drive Style | Screw | | Exterior Finish | Chrome | | Fastener Type | Hex | | Finish Types | Polished | | Global Trade Identification Number | 00885911591430 | | Grade Rating | Commercial | | Included Components | (1) Universal Nut Cracker | | Inside Thread Size | 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm | | Item Diameter | 0.88 Inches | | Item Type Name | UNIVERSAL NUT CRACKER | | Manufacturer | CRAFTSMAN | | Material | Alloy Steel | | Material Type | Alloy Steel | | Maximum Shear Strength | High | | Metal Type | Alloy Steel | | Model | CMMT14117 | | Number Of Items | 1 | | Number of Pieces | 1 | | Part Number | CMMT14117 | | Screw Head Style | Flat | | Size Name | 22mm | | Thread Class | Coarse | | Thread Coverage | Unthreaded | | Thread Size | 5/16, 7/8 | | Thread Style | Unified | | Thread Type | Unified National Coarse (Unc) | | UPC | 885911591430 | ## Product Details - **Color:** black, silver - **Exterior Finish:** Chrome - **Fastener Type:** Hex - **Material:** Alloy Steel - **Thread Size:** 5/16, 7/8 ## Images ![CRAFTSMAN Universal Nut Splitter (CMMT14117) - Image 1](https://m.media-amazon.com/images/I/51lNLlJ7+2L.jpg) ![CRAFTSMAN Universal Nut Splitter (CMMT14117) - Image 2](https://m.media-amazon.com/images/I/51YORo1Cy3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ works well, get stripped easily have to adjust *by J***L on January 10, 2021* I got this to take off the nuts on my used open trailer that were fused on the first one or two worked well but it wasn't actually the product problem it was actually cuz I had very little room on the other side of the trailer underneath to get to the bolts so actually I had to use this product the nut splitter 2 Tac off little by little down to where I could get the nut off, because I was doing this the blade got stripped and wouldn't stay in place but if you just set it manually up against what you want to split it keeps on working and keeps on ticking. * don't get frustrated if this nut splitter keeps slipping off as you use a ratchet.

The set screw broke on me on my second nut. I was trying to split a 19mm one. I ended up having to go at it with a chisel to get it split the rest of the way. Stinks that long term usage won't happen, but I still recommend it because when you need it, nothing else will do. Original review I had a 22mm (the limit for this tool) jam nut for a tie rod that was seized solid and it wasn't budging with my impact. I don't have heat so the only other option was to use this splitter. I was a little worried it wouldn't work after reading reviews, but it came through. You'll notice it actually cuts diagonally rather than straight up and down. Also, it does tend to kind of roll forward as you tighten down. These notes may be manageable if you kind of center punch the nut with a chisel prior. I don't know how may more nuts I'll be able to split with this, but if it works even just this once I think it's worth it. Especially considering it took me less than 5 minutes to split it when I had been fighting with the nut more than 3 hours prior. ## Frequently Bought Together - CRAFTSMAN Universal Nut Splitter (CMMT14117) - CRAFTSMAN CMMT14108 Spiral Screw Extractor - CRAFTSMAN Screw Extractor, 6Piece Set (CMAT136) --- ## 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.hk/products/161391501-craftsman-universal-nut-splitter-cmmt14117](https://www.desertcart.hk/products/161391501-craftsman-universal-nut-splitter-cmmt14117) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-03*
