The Blackspur BB-SD331 3 Piece Socket Adaptor Set is a versatile power tool accessory set designed to convert a compatible drill or driver into a powered nut driver for faster tightening and loosening of nuts and bolts. Manufactured from durable chrome vanadium steel, each adaptor features a 1/4" hex quick-release shank, allowing quick and convenient fitting into compatible drills and impact-style drivers. The built-in spring ball socket retention system helps hold compatible sockets securely in position during use, providing improved control and reducing the chance of the socket slipping off the adaptor. The set includes the three most commonly used socket drive sizes — 1/4", 3/8" and 1/2" — making it ideal for automotive work, mechanical repairs, assembly, workshop maintenance and general DIY.
