Magnetic Bit Holder Set — 3-piece 1/4" Hex (6.35 mm) — stainless steel, locking quick-change Key benefits Secure bit retention: built-in weak magnetism holds bits in place for safer, more reliable fastening while still allowing quick manual bit release. Faster workflow: quick-change locking mechanism lets you install, lock and release bits rapidly, reducing downtime when swapping bits. Durable performance: high-quality stainless steel construction with a smooth surface offers high temperature resistance, good wear resistance and high hardness for long service life. Universal compatibility: standard 1/4 inch (6.35 mm) hex shank fits most cordless screwdrivers, impact drivers and drill drivers. Features Set includes three bit holders: 60 mm, 100 mm, and 150 mm lengths for reach and accessibility in different tasks. 1/4 inch hex handle (6.35 mm) compatibility for use with any tool that accepts standard hex bits. Locking interface combined with weak magnetic retention secures the screwdriver head to the connecting rod and supports quick change and release. Smooth stainless steel body resists heat and wear, maintaining fit and function under repeated use. Typical applications Furniture assembly and home DIY: reach deep screw locations with the 100 mm or 150 mm holders and swap bits quickly during multi-fastener builds. Electrical and cabinetry work: use the magnetic retention to hold small screws while working in tight spaces or overhead. Automotive and maintenance: the durable stainless steel construction and locking system stand up to frequent bit changes and higher use temperatures. What you get Three magnetic bit holders: 60 mm, 100 mm, 150 mm 1/4 inch (6.35 mm) hex shank compatibility Notes on use The built-in magnet is intentionally weak to balance secure retention with easy removal of bits; for heavy-duty magnetic clamping, use a dedicated magnetic socket or adapter. Ensure your tool accepts 1/4 inch (6.35 mm) hex shanks before use. Follow normal safety precautions when changing bits and operating power tools.
