SP3816

Working in confined spaces or on recessed fasteners demands a deep socket that can reach where standard sockets cannot, without sacrificing strength or grip. The Sealey SP3816D is a 16mm deep socket with a 3/8" square drive, cold-forged from Chrome Vanadium steel and hardened and tempered for added strength. The WallDrive® socket configuration maximises contact with the fastener to reduce the risk of rounding, while the knurled ring provides extra grip even with oily fingers. The fully polished chrome-plated finish resists corrosion and makes the socket easy to clean. Suitable for daily professional use as part of Sealey's comprehensive Premier Hand Tools range. Backed by a lifetime guarantee*.
