Proto J5417M 17mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5417M is a 17 mm, 12-point hand socket with a 1/2 inch drive, designed for professional hand-tool applications in mechanical, industrial, and trade service environments. The chrome-plated finish provides corrosion resistance and a clean, easy-to-inspect surface. The standard-length profile fits the majority of fastener access situations without requiring extensions. This socket is suited for use by mechanics, millwrights, pipefitters, and general maintenance technicians who need a reliable, correctly-sized socket for 17 mm hex fasteners.

This socket is appropriate for both residential and commercial maintenance applications wherever 17 mm fasteners are encountered. Common install scenarios include mechanical equipment service, structural fastener work, and general assembly or disassembly tasks. The 1/2 inch drive size pairs with standard 1/2 inch drive ratchets, breaker bars, and torque wrenches found in most professional tool sets. The 12-point design engages fasteners at more contact positions than a 6-point socket, which can be useful when access to the fastener is restricted.

Key Features

• 17 mm socket size for metric fastener applications
• 12-point design allows engagement at 30-degree intervals for restricted-access fastening
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Chrome-plated finish resists corrosion and simplifies cleaning
• Standard-length profile suits most general-purpose fastening tasks

Compatibility

Designed as a standard 1/2 inch drive, 17 mm hand socket compatible with 1/2 inch drive ratchets, extensions, and torque wrenches conforming to standard drive tool configurations.

Installation Notes

Install and remove this socket only when the equipment being serviced is de-energized, depressurized, or otherwise made safe per applicable lockout/tagout procedures. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket for cracks or wear before each use and remove from service if damage is found. No special certifications or permits are typically required for hand-socket use, but always follow the equipment manufacturer's service procedures.
