Proto JSCRM17 Ratcheting Combination Wrench 17 Mm

Product Description

The PROTO JSCRM17 is a ratcheting combination wrench designed for professional trade use in industrial, mechanical, and maintenance applications. Built to a 17 mm head size with a 15-degree offset angle, it delivers the torque control of a box-end wrench combined with the open-end access tradespeople need in tight spaces. The 12-point box end accepts fasteners at more engagement positions, reducing slippage under load. Constructed from steel with a corrosion-resistant black chrome finish, this wrench is built to hold up in demanding shop and field environments. It meets ASME standards and carries a lifetime warranty.

The JSCRM17 fits into any toolkit where controlled fastener work is required on 17 mm fasteners. It is well suited for mechanical contractors, millwrights, pipe fitters, and maintenance technicians working on equipment, flanges, structural fasteners, and machinery. The tether-capable design makes it appropriate for elevated work environments where tool drop is a safety concern, such as elevated platforms, towers, or overhead mechanical work. The straight handle and 8-7/8 inch overall length provide good reach without sacrificing maneuverability in confined spaces.

Key Features

• Ratcheting box end allows fastener rotation without repositioning the wrench
• 15-degree head offset angle provides knuckle clearance in confined areas
• 12-point box end engages fasteners at more positions for reduced slippage
• Corrosion-resistant black chrome finish for durability in harsh environments
• Tether-capable design supports use on elevated work platforms where drop prevention is required
• Meets ASME standards with a lifetime warranty

Compatibility

Designed for use with 17 mm fasteners on standard metric bolts and nuts across industrial, mechanical, and maintenance applications.

Installation Notes

This wrench is intended for use by qualified mechanical tradespeople. Ensure the correct wrench size is matched to the fastener before applying torque to avoid rounding. Do not use extension bars or pipe on the handle to increase leverage beyond the tool's designed capacity. Inspect the ratcheting mechanism before each use and replace the tool if slipping or damage is detected.
