Proto J5208MH Hand Socket 8 Mm 6-point 3/8 Drive

Product Description

The PROTO J5208MH is a 6-point hand socket designed for 3/8-inch drive ratchets and breaker bars used in professional mechanical and maintenance work. The socket fits an 8 mm fastener and features a standard length profile, making it suitable for most accessible bolt and nut applications. The 6-point contact geometry reduces rounding on hex fasteners compared to 12-point designs, and the chrome-plated finish provides corrosion resistance for shop and field use. This socket meets ASME B107.5 standards for hand socket dimensions and strength. It weighs 0.06 pounds and is sold individually.

This socket is used across automotive, industrial, and equipment maintenance applications wherever an 8 mm fastener requires a 3/8-inch drive tool. Standard-length sockets are the go-to choice when clearance allows direct access to the fastener head without requiring extensions. Technicians in automotive service, fleet maintenance, and general mechanical trade will find this size common on engine components, brackets, and accessory hardware.

Key Features

• 8 mm socket size for metric fastener applications
• 3/8-inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• 6-point design reduces fastener rounding under high torque
• Chrome-plated finish resists corrosion in shop and field environments
• Standard length profile for direct-access installations
• Meets ASME B107.5 standards for hand socket tools

Compatibility

Designed for use with 3/8-inch drive ratchets, extensions, and torque wrenches on 8 mm hex fasteners. No specific system compatibility data was provided beyond drive size and socket size.

Installation Notes

This socket is installed by mechanical technicians and general maintenance trades. Ensure the drive tool is fully seated into the socket before applying torque to prevent slippage. Inspect the socket for cracks or wear before use on high-torque fasteners. Store in a dry environment to maintain the chrome finish over time.
