So you only need a PH1 bit or screwdriver (not included). - Suitable for windows and balcony doors: the gear lock has an adjustment lock, which breaks during the first operation and releases the gearbox. - Please note: the hole bar can still be used in the gear. If it is heavily worn, the gear can no longer grasp it properly and move it reliably. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CZL92YJQ | | Batteries Required? | No | | Batteries included? | No | | Colour | Silvery | | Customer Reviews | 3.4 3.4 out of 5 stars (4) | | Date First Available | 11 May 2024 | | Included components | Achkey Worm Gear 2 | | Item Weight | 90 g | | Item model number | WNK Siegenia 2 | | Manufacturer | Achkey | | Part number | WNK Siegenia 2 | | Product Dimensions | 8.3 x 1.4 x 10.6 cm; 90 g | | Size | 2 Items | ## Images ![Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade - Image 1](https://m.media-amazon.com/images/I/71roxcb82fL.jpg) ![Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade - Image 2](https://m.media-amazon.com/images/I/71M-9FkM2-L.jpg) ![Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade - Image 3](https://m.media-amazon.com/images/I/71acHyEltFL.jpg) ![Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade - Image 4](https://m.media-amazon.com/images/I/71KXEC4VFIL.jpg) ![Achkey Siegenia (SI AUBI) Worm Housing Screw Replacement Part Screwable for Window Gears and Balcony Door Repair Gear Lock for Series Favorit Trial Gearbox 3 & 23 (Pack of 2) with HauSun Upgrade - Image 5](https://m.media-amazon.com/images/I/71gFL8vSYIL.jpg) ## Available Options This product comes in different **Size** options. --- ## 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.sc/products/664564387-achkey-siegenia-si-aubi-worm-housing-screw-replacement-part-screwable](https://www.desertcart.sc/products/664564387-achkey-siegenia-si-aubi-worm-housing-screw-replacement-part-screwable) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-07-22*
