ASTM F468 Aluminum 6061-T6 Fasteners are nonferrous aluminum fasteners manufactured from 6061-T6 aluminum alloy for applications requiring low weight, good corrosion resistance, and a useful strength-to-weight ratio. They are available in forms such as bolts, studs, screws, and hex cap screws and are commonly selected for industrial, transportation, marine, electrical, and lightweight engineering applications.
What Are ASTM F468 6061-T6 Fasteners?
ASTM F468 6061-T6 Fasteners are externally threaded fasteners made from nonferrous aluminum alloy in the 6061-T6 temper. ASTM F468 covers nonferrous bolts, screws, studs, and similar fasteners manufactured from specified aluminum and other nonferrous alloys.
6061-T6 is one of the most widely used heat-treatable aluminum alloys. It contains magnesium and silicon as its main alloying additions and achieves improved mechanical strength through heat treatment and artificial aging.
The main reason to select these fasteners is their low density. Aluminum is considerably lighter than carbon and alloy steel, making Aluminum 6061-T6 Bolts and Studs useful where reducing assembly weight is important.
We supply these fasteners in different sizes, thread configurations, head styles, finishes, and customized dimensions according to project requirements.

Why Choose Lightweight High Strength ASTM F468 Bolts?
- Lightweight Construction: Aluminum 6061-T6 has a density of approximately 2.70 g/cm³, making it much lighter than conventional steel. This can help reduce the total weight of equipment and assemblies.
- Good Strength-to-Weight Ratio: The T6 temper provides considerably higher strength than softer aluminum tempers. This makes 6061-T6 useful when engineers need a combination of moderate strength and low mass.
- Corrosion Resistance: 6061 aluminum naturally develops a protective oxide layer. It offers good resistance to atmospheric corrosion and is suitable for many outdoor and industrial environments.
- Nonferrous Construction: ASTM F468 Nonferrous Aluminum Bolts are useful where a nonferrous material is preferred. Aluminum is also generally nonmagnetic, which can be advantageous for certain specialized applications.
- Easy Machining: 6061 aluminum has good machinability, allowing different bolt, stud, screw, and threaded configurations to be produced efficiently.
ASTM F468 Aluminum 6061-T6 Fasteners Applications
Aluminum 6061-T6 Fasteners vs Steel Fasteners
The key advantage of aluminum is its significantly lower density. A component made using aluminum fasteners can therefore be lighter than an equivalent assembly using steel fasteners.
Steel, however, generally provides higher tensile strength, hardness, and wear resistance. Aluminum should therefore not be selected simply because it is lighter. The engineer should compare the actual load, preload, shear requirement, operating temperature, thread engagement, and environmental conditions.
Special attention should also be given to galvanic corrosion when aluminum fasteners are installed against dissimilar metals. Suitable isolation methods, coatings, washers, or surface treatments may be required depending on the environment.
