AN Hex Wrench #12 or 1-1 /4in Black Anodize Alum

The AN Hex Wrench #12 or 1-1/4in Black Anodize Aluminum is a precision tool designed for marine and aviation hydraulic systems where AN (Army-Navy) fittings dominate. Built by Specialty Products Company, this single-end hex wrench serves boaters, mechanics, and maintenance technicians working with high-pressure fluid lines, fuel systems, and power steering components.

Machined from aluminum and finished in black anodize, this wrench delivers corrosion resistance critical to saltwater and freshwater environments where oxidation compromises tool longevity and fitting integrity. The black anodized coating protects against rust while maintaining a professional appearance and reducing glare in bright conditions on deck. Its compact 7.7-inch length and lightweight 0.24-pound design fit easily into a toolbox, galley locker, or emergency repair kit without adding bulk.

The hex configuration ensures positive engagement with AN-12 fittings to prevent rounding and fluid loss under pressure. This wrench is indispensable for captains and boat owners who perform their own maintenance, eliminating costly yard visits for routine hose or fitting replacement. Marine technicians and mechanics rely on AN hex wrenches as core components of their service inventory.
