Aluminum Bolts – Lightweight, High-Strength Fastening Solutions

As a premier supplier and manufacturer in China, TSM TECHNOLOGY offers precision-engineered Aluminum Bolts in aerospace-grade 6061-T6 and ultra-strong 7075-T6 alloys. Whether you need to buy standard hex bolts or custom socket caps, our Aluminum Bolts deliver superior corrosion resistance, strength-to-weight ratio, and competitive price and cost advantages for automotive, electronics, marine, and aviation applications.

What Are Aluminum Bolts?

Aluminum Bolts are threaded fasteners made from high-purity aluminum alloys (commonly 6061 and 7075). They weigh up to 60% less than steel bolts yet maintain excellent tensile strength (up to 500 MPa) and natural oxicorrosion protection. Ideal for weight-sensitive designs, Aluminum Bolts resist rust, simplify assembly, and lower material cost.

Types of Aluminum Bolts

Hex Head Bolts – Standard M3–M24 & 1/8″–1″ diameters.

Socket Head Cap Screws – High-precision, low-profile heads.

Flange Bolts – Built-in washer for load distribution.

Button Head Bolts – Low head height for aesthetics.

Carriage Bolts – Dome head with square neck for wood.

All styles come in 6061 for general use and 7075 for ultimate strength, with finishes like clear anodizing, black anodizing, or zinc plating to match any project.
