Snapped a 1/2” breaker bar trying to undo them. This 1” bar overcame the problem with ease, although not without a huge amount of force. Car now has new set of studs all round as the old ones are probably unsafe. Have a tractor to strip down in a few weeks time and am expecting this to make short work of any high torqued nuts. Will follow through on this. ## Frequently Bought Together - US PRO Tools 1" Drive x 40" Long Power Breaker Knuckle Bar Torque 512Nm 4164 - US PRO Tools 3 Piece 1" DR Impact Extension Bar Set Socket Bars 3423 - Trintion 10Pcs Impact Socket Set 1 Inch Metric Large Socket Set 22mm to 50mm Deep Wrench Sockets Drive Shaft Auto Car Tool Set with Plastic Storage Box for Vehicles Maintenance --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/175888680-tools-1-drive-x-40-long-power-breaker-knuckle-bar](https://www.desertcart.tn/products/175888680-tools-1-drive-x-40-long-power-breaker-knuckle-bar) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-27*
