Hex Nuts are six-sided nuts designed to complement bolts, screws, and studs in mechanical, construction, and industrial applications. Manufactured from carbon steel (Grade 4, 5, 8), stainless steel (304/316), or alloy steel, they feature precise threads for reliable torque transmission and are available in various finishes for corrosion resistance.
- Material:
- Carbon Steel (zinc-plated, Grade 4/5/8).
- Stainless Steel (304/316, passivated).
- Alloy Steel (heat-treated for high-strength applications).
- Size Range:
- Metric: M3–M100 (ISO 4032, ISO 4034).
- Imperial: 1/4"–4" (UNC/UNF, ASME B18.2.2).
- Type:
- Standard Hex Nuts (薄型 / 重型: thin/heavy duty).
- Lock Nuts (nylon insert, prevailing torque).
- Flange Nuts (with washer face for increased bearing area).
- Finish: Zinc plating (yellow/clear), hot-dip galvanized (HDG), Dacromet, or black oxide.
- Thread Class: 6H (metric), 2A/2B (imperial) for standard tolerance; precision classes available on request.
- Standard Carbon Steel/Zinc-Plated: 10,000 pieces (common sizes like M6–M24 in stock).
- Stainless Steel/Lock Nuts: 5,000 pieces (e.g., 316 stainless or nylon insert types).
Factory Advantages: ISO-certified production, thread gauge testing (GO/NOGO), support for non-standard thread pitches and custom coatings, with lead times of 7–15 days for bulk orders.
- General Machinery: Securing motors, pumps, and gearboxes.
- Construction: Structural steel connections, scaffolding, and formwork.
- Automotive: Engine components, chassis parts, and body assemblies.
- Electronics: Panel mounting and electrical enclosure fastening.
- Torque Compatibility: Standard hex design works with wrenches, sockets, and automated tools.
- Corrosion Resistance:
- HDG coatings (1,000+ hours salt spray) for outdoor use.
- 316 stainless steel suitable for marine or chemical environments.
- Locking Solutions: Lock nuts prevent loosening in high-vibration applications (e.g., automotive engines).
- Non-Standard Sizes: Oversized nuts (M120+), metric-imperial hybrid threads, or thin-wall designs.
- Special Coatings: PTFE (anti-seize), zinc-nickel (high-corrosion resistance), or color-coded finishes.
- Certifications: Load test reports and material certifications (MTC) for critical projects.
