6061-T6 Aluminum Construction
The EVIL ENERGY AN wrench is manufactured from 6061-T6 aluminum alloy.
This material provides a useful combination of low weight, strength, and machinability.
Unlike conventional hardened steel wrenches, an aluminum AN wrench is intended for use with aluminum fitting hexes.
However, aluminum tools can still scratch anodized fittings, especially when the jaws are dirty, improperly adjusted, or allowed to slip.
How to Protect Anodized AN Fittings
For additional cosmetic protection, EVIL ENERGY recommends applying electrical tape to the wrench jaws before use.
This can help reduce direct metal-to-metal contact between the wrench and the fitting.
For best results, keep the jaws clean, adjust them snugly to the fitting, and apply controlled force.
Electrical tape does not guarantee scratch-free installation, and excessive tape thickness may reduce proper jaw engagement.
Four-Surface Contact for Improved Grip
The EVIL ENERGY adjustable wrench is advertised with a four-surface contact design.
This configuration is intended to distribute force across multiple fitting surfaces rather than concentrating the load at a single point.
Proper jaw engagement can help reduce slipping and minimize damage to aluminum fitting hexes.
Always position the wrench fully over the fitting and ensure the adjustable jaw is snug before tightening or loosening.
Compact Curved Handle Design
The EVIL ENERGY wrench measures approximately 7.2 inches long and features a curved handle profile intended to improve comfort and control.
Its compact size makes it convenient for garage toolboxes, portable automotive tool kits, and performance plumbing installations.

EVIL ENERGY Adjustable AN Wrench vs. Standard Steel Wrench
| Feature | EVIL ENERGY Aluminum AN Wrench | Conventional Steel Adjustable Wrench |
|---|---|---|
| Primary purpose | Aluminum AN fitting installation | General-purpose fastening |
| Material | 6061-T6 aluminum | Typically steel |
| Weight | Lightweight | Generally heavier |
| AN fitting protection | Designed for compatible aluminum fittings | Greater risk of cosmetic damage |
| Size adjustment | 3AN–16AN fitting range | General jaw opening range |
| Hardened steel fasteners | Not recommended | Usually more suitable |
Although the EVIL ENERGY wrench is designed for aluminum fittings, it should not be used as a substitute for a torque wrench when a manufacturer specifies an exact tightening torque.
How to Use the EVIL ENERGY Adjustable AN Fitting Wrench
-
Identify the AN fitting size and inspect the fitting hex.
-
Confirm the fitting is made from a compatible material.
-
Adjust the wrench jaws to the appropriate opening.
-
Apply electrical tape to the jaws if additional cosmetic protection is desired.
-
Position the wrench squarely over the fitting hex.
-
Tighten the adjustment until the jaws fit snugly without excessive play.
-
Hold the mating component with a suitable backup wrench where required.
-
Tighten the fitting according to the fitting manufacturer’s instructions.
-
Inspect the fitting for damage and verify proper sealing after assembly.
Important Installation Precautions
-
Do not use the wrench on incompatible hardened steel fasteners.
-
Do not use excessive force or add a cheater bar to the handle.
-
Do not apply force when the jaws are only partially engaged.
-
Do not assume every AN fitting uses the same hex dimensions.
-
Do not rely on the wrench alone to establish correct fitting torque.
-
Do not overtighten AN flare connections in an attempt to stop leaks.
