Hex Hollow Nut
Hex Hollow Nut is a high-precision fastener designed for shaft parts, primarily used to fix shafts, pins, and other components to prevent rotation or axial movement. Crafted from 304 stainless steel (containing 18% chromium and 8% nickel), it offers excellent corrosion resistance (to atmospheric corrosion, organic acids, inorganic acids, and salt spray). The product features a hexagonal head + hollow cylinder + internal thread structure:
Hexagonal Head: Complies with national standard GB/T 809, with precise across-flats dimensions, enabling easy tightening with universal tools (wrenches, sockets) and high installation efficiency;
Hollow Cylinder: Uniform wall thickness (1.5-5mm) allows shaft parts to pass through, reducing weight and saving installation space without the need for additional sleeves or washers;
Internal Thread: Regular thread profile (metric M series) ensures tight fit with bolts, providing reliable fixation.

Product Parameter
The following are common metric specifications (compliant with GB/T 809). Non-standard customization (e.g., adjusting wall thickness, length, material) is available:
Note: Specification is expressed as "M×L×S×t" (e.g., M6×20×10×4 means nominal thread diameter 6mm, length 20mm, across flats 10mm, wall thickness 4mm); weight is approximate and may vary slightly.
| Nominal Thread Diameter (M) | Nominal Length (L, mm) | Across Flats (S, mm) | Wall Thickness (t, mm) | Approximate Weight (g/piece) |
| M3 | 5-30 | 5.5 | 1.5-2.5 | 0.1-0.5 |
| M4 | 6-40 | 7.0 | 2.0-3.0 | 0.2-1.0 |
| M5 | 8-50 | 8.5 | 2.5-4.0 | 0.3-1.5 |
| M6 | 10-60 | 10.0 | 3.0-5.0 | 0.5-2.5 |
| M8 | 12-80 | 13.0 | 4.0-6.0 | 1.0-4.0 |
| M10 | 15-100 | 16.0 | 5.0-8.0 | 2.0-6.0 |
| M12 | 18-120 | 19.0 | 6.0-10.0 | 3.0-10.0 |

Product Feature
Hollow Design, Space-Saving: The hollow cylinder structure allows shaft parts to pass through directly, eliminating the need for additional sleeves or washers. This reduces weight (30%-50% lighter than solid nuts) and is ideal for small devices or space-constrained applications (e.g., electronic equipment, precision machinery).
Hexagonal Head, Easy Installation: The hexagonal head (compliant with GB/T 809) fits universal tools (wrenches, electric screwdrivers), ensuring high installation efficiency. Precise across-flats dimensions prevent slipping during tightening.
304 Stainless Steel, Corrosion-Resistant: Made of high-quality 304 stainless steel, it resists atmospheric corrosion, organic acids (e.g., acetic acid in food processing), inorganic acids (e.g., hydrochloric acid), and salt spray. Suitable for humid or corrosive environments (e.g., machine tool coolants, automotive engine compartments).
High-Precision Thread, Reliable Fixation: The internal thread is machined via CNC lathe, with a regular profile (error ≤0.02mm) and tight fit (IT6 grade). It ensures secure fixation without stripping, even under vibration.
Customization Service: The factory supports non-standard customization (e.g., adjusting wall thickness, length, material) to meet personalized needs (e.g., special specifications like M14×30×22×7).
Application Fields
Machine Tool Industry: Used to fix shaft parts (e.g., main shafts, lead screws) in machine tools. The hollow design allows main shafts to pass through, and the hexagonal head facilitates installation and adjustment. 304 stainless steel resists corrosion from machine tool coolants.
Precision Machinery: Used for fixing small shaft parts (e.g., camera mounts, small motor shafts) in precision equipment. High-precision threads ensure no loosening, and the hollow design saves space—ideal for small devices.
Automotive Industry: Used to fix transmission shafts, engine components (e.g., camshafts, crankshafts) in automobiles. 304 stainless steel withstands high temperatures and corrosion in engine compartments, while the hexagonal head eases maintenance.
Electronic Devices: Used for fixing small shaft parts (e.g., printer rollers, camera rotors) in electronic devices. The hollow design allows shafts to pass through, reducing weight without affecting device performance.
Generators: Used to fix rotors and stators in generators. High-precision threads prevent rotor rotation, and 304 stainless steel resists vibration and corrosion during operation.
