Tight-space maintenance: Reach and turn a filter cap located beneath an air intake hose or other close-fitting components. How it performs in the workshop Works with common 3/8-inch hand tools for precise control and leverage. Flat, shallow profile lets you get the socket onto the housing cap where deeper sockets cannot fit. 6-point geometry delivers even contact and efficient transmission of torque for stubborn caps. Who it’s for DIY mechanics and professional technicians performing routine oil or fuel filter maintenance on vehicles that use cartridge-style housings. Anyone who needs a low-profile 36 mm socket that fits a 3/8-inch drive and provides reliable engagement in tight engine spaces.
