Product Number: IS3818D
Standard sockets can struggle to reach deeply recessed or proud fasteners, leaving you exposed to slippage and wasted time. The Sealey IS3818D is an 18mm deep impact socket with a 3/8" square drive, engineered specifically for use with air impact wrenches where high torque and fastener reach are both required. Manufactured from drop-forged Chrome Vanadium steel, it features Sealey's WallDrive® profile designed to grip the flats of a fastener rather than the corners, reducing the risk of rounding and improving torque transfer. The socket is hardened and tempered for added strength and carries a phosphate finish for greater corrosion resistance, making it well suited to professional workshop environments. Part of Sealey's Premier Hand Tools range and backed by a lifetime guarantee.
