Designed for use with a screwdriver handle or electric screwdriver that uses a hex drive or a three-jaw chuck. This drive sleeve adapter helps you work more conveniently and with less effort. Made of chrome-vanadium steel, it offers high strength and good abrasion resistance, and is not easy to rust. After installation, the original hex size can be converted to a square drive size, making it a practical accessory for drive-size conversion. Exquisite workmanship and fine craftsmanship contribute to durability and reliable performance. The adapters come in different sizes to meet varying needs, and are suitable for wood drilling. 2-3 practical use scenarios: - Convert a hex-drive screwdriver to a square-drive setup to use square-drive bits for faster bit changes. - Use in furniture assembly or cabinetry projects where square-drive bits are preferred for secure seating and reduced cam-out. - Work in tight spaces by adapting to the necessary drive size without changing tools.
