Proto J15038 Impact Socket 1-1/2 in Drive 2-3/8 in 6-point

Product Description

The PROTO J15038 is a heavy-duty impact socket designed for high-torque fastening and removal applications in professional trade environments. Built around a 1-1/2 inch drive, it accepts 2-3/8 inch hex fasteners and features a 6-point contact geometry that concentrates force on the flats of the fastener, reducing the risk of rounding. Overall length is 3-7/8 inches. This socket is intended for use with 1-1/2 inch drive impact wrenches and is sized for large-scale mechanical, industrial, and heavy equipment fasteners. Automotive technicians, industrial mechanics, and heavy equipment service professionals are the primary users.

The J15038 is suited for industrial maintenance, heavy equipment repair, and large-format mechanical assembly where 2-3/8 inch hex fasteners are common. Its 1-1/2 inch drive size places it in the heavy-duty category, typically paired with pneumatic or hydraulic impact wrenches found in fleet maintenance shops, manufacturing facilities, and construction equipment service operations. The compact 3-7/8 inch overall length helps in applications where access is limited.

Key Features

• 1-1/2 inch drive size rated for high-torque impact tool use
• 2-3/8 inch hex socket size for large-format fasteners
• 6-point drive geometry reduces fastener rounding under load
• 3-7/8 inch overall length for a compact, manageable profile
• Hex drive style provides positive engagement on hex-head fasteners and bolts

Compatibility

Designed as a standard OEM-style impact socket compatible with 1-1/2 inch drive pneumatic, hydraulic, and electric impact wrenches used in heavy-duty industrial and mechanical service applications.

Installation Notes

Installation and removal should be performed by qualified mechanics familiar with heavy-duty impact tooling and the torque requirements of the fasteners being serviced. Always ensure the socket is fully seated on the drive anvil and fastener before applying power to the impact wrench. Inspect the socket for cracks or wear before each use, and never use impact sockets with standard ratchets or torque wrenches not rated for impact service.
