Proto J1218MBASD Combination Wrench 18 Mm 12-point

Product Description

The PROTO J1218MBASD is a 12-point combination wrench designed for professional-grade fastener work in industrial, mechanical, and maintenance environments. Built from corrosion-resistant steel, it features an 18 mm head size with a 15-degree offset angle that provides clearance in tight spaces where a straight wrench cannot seat properly. The overall length of 10.5 inches delivers the leverage needed for standard torque applications without adding unnecessary bulk. Tether-capable design makes it suitable for work at height or in environments where dropped tools create safety hazards. Licensed trades and industrial mechanics reach for this wrench when precision and durability are non-negotiable.

This wrench is suited for residential and commercial mechanical work, automotive service, industrial maintenance, and utility applications where metric fasteners are standard. The 15-degree head offset reduces knuckle clearance issues in confined areas around equipment panels, flanges, and structural fasteners. The straight handle provides a familiar grip profile for mechanics accustomed to standard combination wrench geometry. Its tether-capable feature meets the requirements of drop-prevention programs common in overhead and elevated work environments.

Key Features

• 18 mm head size fits standard metric fasteners commonly found in mechanical and industrial applications
• 15-degree offset head angle improves clearance in confined or obstructed work areas
• 12-point box end engages fasteners at multiple positions for use in tight swing arcs
• Tether-capable design supports tool-drop prevention programs for elevated work
• Corrosion-resistant steel construction for durability in shop and field conditions
• Meets ASME B107.100-2010 standards for hand tool performance and safety

Compatibility

Designed as an OEM-style replacement or direct addition to metric combination wrench sets for professional mechanics, industrial maintenance technicians, and tradespeople working with 18 mm fasteners.

Installation Notes

This wrench is a hand tool requiring no installation. Before use in tether applications, verify the attachment point and tether hardware are rated for the tool weight and application requirements. Inspect the wrench for cracks or deformation before each use, particularly on the box end. When working on energized or pressurized systems, follow applicable lockout and isolation procedures before applying the wrench to fasteners.
