Product Description

The PROTO J52122 is a 10-piece standard socket set built for professional trade use in automotive, mechanical, and industrial service applications. The set runs a 3/8 inch drive and covers sizes from 5/16 inch through 7/8 inch in standard inch measurements. Each socket features a 6-point design for solid contact on fastener flats, reducing the risk of rounding under torque. The chrome finish resists corrosion and simplifies cleanup after use. Licensed mechanics, HVAC technicians, plumbers, and industrial maintenance techs will find this set useful for general fastener work across a wide range of equipment.

This socket set is suited for residential and light commercial service work where a 3/8 inch drive ratchet is the preferred tool.

The compact size range fits well in a field service bag or tool cart drawer alongside other 3/8 inch drive accessories.

Store sockets on the provided rail or in a designated tray to prevent loss and damage.
