RS PRO 36-Piece 1/4 in, 3/8 in

This comprehensive RS PRO socket set has 21 sockets ranging from 4.5 mm to 19 mm. The kit also comes with 1/4-inch and 3/8-inch sized extension arms, quick release go-thru ratchets, adaptors and four flat and Phillips head screwdriver bits.
All parts in this kit are made of steel, so it's designed to last and is suitable for a range of heavy-duty tasks, from removing seized fasteners to tightening nuts with a large amount of force. The steel material also makes the parts resistant to corrosion, which means you can use them in damp or humid environments and not have to worry about them rusting. The ratchets have a quick-release feature, which is useful when changing sockets during complex projects involving multiple sizes of fastener. They also have a reversible ratcheting system that allows you to crank them back and forth, so you can tighten and loosen fasteners without having to remove or reposition the ratchet.
This set has been rigorously tested for quality and reliability. A socket set like this one is often used by car mechanics for adjusting fittings or by marine technicians working on boat engines.
