Hex Nut – Reliable Fastening for Every Industry

The Hex Nut (Hexagon Nut) is one of the most commonly used fasteners worldwide, designed to mate with external threaded components such as bolts, screws, and studs. Its six-sided shape allows for easy installation with standard wrenches or sockets, providing a secure and vibration-resistant joint. At Malaxy, we produce high-precision hex nuts in a full range of materials, grades, and finishes to meet the demands of construction, automotive, heavy machinery, and infrastructure projects.

✔ Universal compatibility with standard bolts and studs
✔ Available in coarse and fine threads
✔ Multiple strength grades from Class 4 to Grade 8 and Class 12
✔ Wide range of surface coatings for corrosion protection

Key Features & Advantages

• Standardized Geometry – Conforms to DIN, ISO, ASME, and GB standards for global interchangeability

• High Strength Options – From commercial grade (Class 4) to high-strength (Grade 8 / Class 12), suitable for preload control

• Vibration Resistance – Can be paired with lock washers or supplied as nylon-insert lock nuts (upon request)

• Corrosion Protection – Plain, zinc plated (clear/yellow), hot-dip galvanized, Dacromet®, and Geomet® coatings available

• Cost-Effective – Simple design allows mass production at competitive prices without sacrificing quality

Material & Grade Options

Surface Finishes:

• Zinc plated (Cr3+ or Cr6+ free)

• Hot-dip galvanized (heavy-duty)

• Black oxide (minimal build-up)

• Phosphate & oil (for temporary corrosion protection)

• Dacromet / Geomet (high salt spray resistance)

⚙️ Quality Standards & Certifications

Our hex nuts are manufactured and tested according to international fastener standards:

• DIN 934, DIN 6915 – German standard for hex nuts and heavy hex nuts

• ISO 4032 / 4033 / 4034 – Metric hex nuts (style 1, style 2, thin)

• ASME B18.2.2 – American standard for hex nuts (UNC, UNF, 8UN)

• ASTM A194 / A563 – Carbon and alloy steel nuts for high-pressure/high-temperature service

• GB/T 6170 / 6175 – Chinese national standard

• RoHS, REACH – Environmental compliance

Each lot undergoes:
✔ Dimensional inspection (thread gauge, width across flats, thickness)
✔ Mechanical testing (proof load, hardness)
✔ Surface coating thickness check
