Thanks** A: HI these are a 1/4" square end, as long as your universal socket is that size then yes. or even with a reducer this would work ( if your universal socket was 1/2") **Q: Not clear about the sizes. Is the drive 1/4 inch and the bit that goes into the socket 3/8 inch?** A: 3/8 drive.. **Q: Is the drive 1/4 inch (the hole that fits on the ratchet)?** A: YES THEY ARE 1/4" SQUARE MALE ONE END & 1/4" SQUARE FEMALE THE OTHER END & THEY PUSH TOGETHER TO MAKE UP DIFFERENT LENGTH COMBINATIONS BUCKO COVENTRY **Q: Can this be used to extend a standard wrench to create leverage in order to unscrew something very tight? (a bike cassette)** A: They won’t create leverage they will just give you extra length , like if you have a nut down a tight hole , so they extend your reach. ## Frequently Bought Together - Amtech I3700 3 Piece 6mm (1/4'') Short Extension bar Set - OriGlam 1/4-Inch Drive Ratchet, Quick-Release Ratchet, Drive Quick Release Ratchet, Drive Flex Quick-Release Ratchet, Drive Torque Wrench for Repair Tools - NEILSEN TOOLS CT0753 11 Piece Drive Deep Socket Set on Holder,1/4" --- ## 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.com.pa/products/50704085-amtech-i3700-3-piece-6mm-1-4-short-extension-bar](https://www.desertcart.com.pa/products/50704085-amtech-i3700-3-piece-6mm-1-4-short-extension-bar) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-11*
