Review: Stahlwille Quality - Nice brushed chrome finish, superb locking mechanism. A must have for working on newer vehicles. No worries about dropping a socket while working in hard to reach areas of your motor. Review: Not cheap, but definitely worth it! - These are pretty much the best locking extensions out there. They have super narrow shafts and the locking mechanism is very compact and holds securely. I trust them for all spots where I can't afford to lose a socket. They are expensive relative to other brands, but are with the price. ## Features - SAFETY. QuickRelease secures every single link in the toolchain - from the ratchet to the extension to the socket wrench insert. - BETTER. Stahlwille sockets prevent the loss of socket wrench inserts even at screw points that are difficult to access or in long threaded holes. Other security systems on the market only fix the first insertion tool on the ratchet. - ERGONOMICALLY DESIGNED. Our sockets are Easily accessible and our ergonomically optimized mechanism secures the tool without taking up additional space. - MORE EFFICIENT. The tool change is not only safe but also faster. - DIN 3123/ISO 3316 COMPLIANT and MADE IN GERMANY. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C11P8Z8 | | Best Sellers Rank | #670,593 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,650 in Socket Wrenches | | Bit Compatibilities | 1/4" (6.3mm) drive bits | | Brand | Stahlwille | | Brand Name | Stahlwille | | Customer Reviews | 4.6 out of 5 stars 86 Reviews | | Drive Bit Shank Style | Flat | | Drive System | Square | | Finish Type | Powder Coated | | Finish Types | Powder Coated | | Global Trade Identification Number | 04018754141227 | | Included Components | 6,3 mm (1/4") QuickRelease extension L.150 mm d.11,6 mm | | Item Length | 4.02 Inches | | Item Weight | 0.07 Kilograms | | Manufacturer | Stahlwille | | Material | Stahlwille | | Material Type | Stahlwille | | Model Number | 405QR | | Number of Pieces | 1 | | Unit Count | 1.0 Count | ## Images ![11011002 QuickRelease Extension No. 405QR, 1/4" Square Drive, Size 4, with QuickRelease Safety Lock, Chrome Plated Finish, Length 102mm, Made in Germany - Image 1](https://m.media-amazon.com/images/I/21shbwu8BdL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Stahlwille Quality *by T***B on July 31, 2024* Nice brushed chrome finish, superb locking mechanism.
