Professional 7075 aluminum lug nuts Manufacturer

FastenMetal LTD specializes in manufacturing high-quality 7075 aluminum lug nuts, strictly in accordance with ISO 7042 and GB/T 3190 international standards. Made from 7075 aluminum alloy (AlZn5.5MgCu) in the T73 heat-treated condition, our products offer tensile strength over 540 MPa and yield strength above 460 MPa—delivering superior mechanical performance compared to ordinary steel while remaining lightweight.

Each lug nut is precisely crafted using advanced CNC machining and thread rolling processes, achieving 6g/6H-grade fit accuracy. We offer various structural designs, including standard hex and flanged types, with customizable sizes from M6 to M24mm, along with optional surface finishes such as anodizing and chrome plating.

Special anti-loosening features are optimized for wheel applications, maintaining reliable performance in harsh environments ranging from -30℃ to 200℃. Every product comes with a 72-hour salt spray test report and material certification (Zn 5.1–6.1%, Mg 2.1–2.9%).

Leveraging large-scale production capabilities, we provide cost-effective solutions for automotive tuning, racing, and motorsport industries. Bulk orders can be delivered within 3–7 days, and all products undergo hardness testing (HRB80–95) and torque inspection to meet DIN, JIS, and other international standards.

Our fastener range includes car bolts, marine bolts, chemical bolts, stud bolts, threaded rods, and other high strength bolts.

1.Exotic Material Bolts

For bolts used in extreme environments such as marine, chemical, oil & gas, and aerospace industries,normally need higher corrosion resistance. FastenMetal supply custom bolts and metal components made from exotic materials such as Inconel, Monel, Titanium, and various types of duplex stainless steel.

2.High Strength Bolts

When regular bolts don’t meet strength requirements, we can produce bolts with strength grades up to Grade 12.9 for your requirements.

3.Custom Shapes and Sizes

We manufacture fasteners in special shapes, lengths, and diameters according to specific applications—fully customized according to your drawings.

In addition to fasteners, we offer custom stamping and metal fabrication services. We have 12 punching machines and press machines for large sheet metal forming and bending, we can handle part thicknesses up to 6mm.

In many of these cases, the customer’s engineering department will provide us CAD drawings and tell us the materials,strength grade they need. We produce samples for customers approval before bulk production.
