Proto J5441-17MXL Hand Hex Bit Socket 1/2 in 17 Mm

Product Description

The PROTO J5441-17MXL is a long hex bit socket designed for hand tool use in heavy-duty fastening applications. Built around a 1/2 inch drive, it accepts a 17 mm hex bit and delivers the extended reach required for deep or recessed fasteners. The overall length of 7.25 inches and a bit length of 5.125 inches make this socket well-suited for applications where standard-length sockets cannot reach the workpiece. Mechanics, pipefitters, millwrights, and maintenance technicians who work on machinery, equipment assemblies, and structural components will find this socket a practical addition to a professional drive set.

This hex bit socket is used in industrial maintenance, mechanical assembly, and general trade service work where 17 mm hex-drive fasteners are encountered. The long overall length makes it appropriate for engine work, equipment installations, and structural bolt applications where socket depth is a limiting factor. It is sold individually and is compatible with standard 1/2 inch drive ratchets, breaker bars, and torque wrenches.

Key Features

• 1/2 inch drive fits standard ratchets, breaker bars, and torque wrenches
• 17 mm hex bit size for common industrial and mechanical fasteners
• Extended overall length of 7.25 inches provides deep-reach capability
• 5.125 inch bit length accommodates recessed or deeply set hex fasteners
• Long hex bit socket format reduces the need for extension bars in many applications

Compatibility

Designed as an OEM-style replacement or direct-fit hand tool socket for use with standard 1/2 inch drive tool sets in professional trade and industrial maintenance applications.

Installation Notes

This socket is installed by hand tool professionals including mechanics, millwrights, and maintenance technicians. Ensure the socket is fully seated on the drive tool before applying torque. Inspect the socket and drive tool for wear or damage before use, and never exceed the rated capacity of the drive tool. Always select the correct hex size to avoid rounding fastener heads.
