High-Strength 2024 Aluminum Hex Bars

Balance high strength and workability. Initially designed for aircraft frames, 2024 aluminum is turned into parts that need to be especially strong, such as couplings for servomotor shafts. It’s one of the most widely used high-strength alloys, made into fasteners, gears, and everything in between. It’s also easier to form and weld than 7075 aluminum, among the strongest aluminum alloys out there.

Extra-High-Strength 7075 Aluminum Hex Bars

Among the strongest aluminum alloys, 7075 boasts a yield strength that rivals carbon steel rebar. Originally made for aircraft frames, it's now turned into gears, machine keys, and other high-stress parts. It's a good substitute for 2024 aluminum when forming and welding aren't top concerns.

Anodized Multipurpose 6061 Aluminum Hex Bars

All the benefits of 6061 aluminum, plus extra wear and corrosion resistance. Bonded with a thick coating (anodizing), these bars resist scratches and won’t degrade as quickly as uncoated bars.

6061 is the most widely used aluminum, made into everything from pipe fittings to containers to airplane parts. It balances strength and corrosion resistance, not to mention it’s easy to machine and weld.

Hard Anodize—Our most durable anodized coating, with a surface so hard it rivals case-hardened steel. However, it makes this aluminum more difficult to machine than uncoated aluminum.

Internally Threaded Turnbuckle-Style Connecting Rods

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages. Rods have a hex-shaped body so you can adjust them with a wrench.

Note: The end with the left-hand threads is marked with a groove.

Aluminum—Aluminum rods are lightweight and have good corrosion resistance.
