-10 Steel Wrench

The ALLSTAR PERFORMANCE -10 Steel Wrench is a single-end AN wrench engineered for precision hydraulic and pneumatic line assembly in high-performance automotive and motorsports applications. This tool is purpose-built for technicians, fabricators, and race teams who demand reliable fastening on AN fittings where accuracy and durability are non-negotiable. The -10 AN size designation indicates compatibility with -10 AN (5/8-inch) fittings, making it an essential item for fuel system plumbing, brake line installation, and custom fluid delivery systems.

Constructed from durable steel with a rubber-coated handle, this wrench combines strength with user comfort during extended use. The rubber coating provides superior grip control and reduces hand fatigue when working in high-vibration environments or under tight tolerances. The black finish protects against corrosion and wear, while the single-end design allows for straightforward, one-tool access to AN line connections. At 0.32 lbs and measuring 12.05 inches in length, the wrench delivers optimal leverage without excess weight, critical when working in engine bays or confined spaces where bulky tools are impractical.

This wrench is ideal for anyone assembling or servicing AN hydraulic systems, including drag racers, circle-track competitors, street rod builders, and professional shops. It excels in applications requiring -10 AN fitting torque specs where precision matters—fuel injection systems, nitrous oxide lines, transmission cooler plumbing, and custom cooling circuits all benefit from dedicated sizing. Technicians value single-end AN wrenches for their simplicity and reliability; this steel construction ensures years of service across multiple projects and builds.
