Gray Tools 3188 combination wrench 12 point 2-3/4 in tool storage

Professional wrench for large fasteners

The Gray Tools 3188 combination wrench addresses 2-3/4 inch hex fasteners with a 12 point drive. Precision broaching delivers a tight, secure fit on big bolts. Satin chrome finish provides maximum resistance against corrosion. Meets ANSI standards for professional use.

Suited for heavy equipment maintenance

Mechanics working on industrial machinery, agricultural equipment or large vehicle assemblies will find this size necessary. The 12 point geometry allows engagement at more angles in confined spaces. Buyers who only service passenger cars or light trucks will rarely encounter fasteners this large. Anyone needing a ratcheting function should look at a different tool type.

Single size with no redundancy

This wrench handles one specific hex dimension and offers no alternative capacity. The 12 point broach gives adequate grip on worn or rounded heads within that size. It runs out when the fastener differs even slightly from 2-3/4 inch. No storage case or organiser is included with the tool itself.
