About this item
- 【Universal Compatibility】From assembling furniture and installing gym equipment to repairing appliances and tightening screws, this set of metric and imperial allen key bits comprehensively covers the vast majority of hex screw sizes found in households. Compatible with electric screwdrivers, manual screwdrivers, drills, and other tools.
- 【Crafted from S2 Tool Steel for Durability】Allen key drill bit set made from high-quality S2 alloy steel with CNC precision-machined tips and professionally heat-treated to a hardness of HRC 58–62. Offers excellent torsional strength and wear resistance, effectively preventing bit twisting or breakage under high-pressure tasks and extending service life by up to 10 times.
- 【Strong Magnetic Head】Hex bit set features a universal 1/4" shank for quick insertion into your electric screwdriver or ratchet wrench. The powerful magnetic tip securely holds screws in place, preventing them from falling during rapid starts or when working overhead or at awkward angles. Greatly improves efficiency and safety during installation, repair, or fastening tasks.
- 【Dual Metric and Imperial Sizes – A Complete Set】The hex drill bit set includes 10 metric (MM) and 10 imperial (INCH) commonly used sizes, perfectly meeting the needs of disassembly and installation for screws of different standards. Whether for imported equipment, car maintenance, or household appliances, this single set handles it all – no more searching for specific sizes.
- 【Specifications】Metric sizes: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 6mm, 7mm, 8mm. Imperial sizes: 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 3/16", 7/32", 1/4", 5/16". Length: 50mm.
- 【Fits Various Screw Sizes】Designed for over 95% of hex screw applications on the market. Ensures a tight, gap-free fit within the screw head to effectively transfer torque, fundamentally preventing screw stripping or rounding caused by size mismatch and keeping your screws in perfect condition.
- 【Quality Service】Each impact allen key set comes with a sturdy plastic case for easy portability and storage. If you encounter any quality issues, please contact us for a replacement – we will resolve the matter promptly.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
