Stainless Steel Positioning Sleeve
Stainless Steel Positioning Sleeve is a cylindrical precision fastener made of high-quality 304 stainless steel (containing 18% chromium and 8% nickel) with internal threads. Its core function is to precisely position and fix parts such as shafts, pins, and rods. By tightly mating with bolts via internal threads, it ensures parts maintain their correct position during assembly, effectively preventing loosening or displacement caused by vibration, impact, or repeated disassembly.

Product Parameter
The following are common metric specifications (non-standard customization is available, e.g., adjusting diameter, length, wall thickness):
Note: Specification is expressed as "M×L×t" (e.g., M6×20×3 means nominal thread diameter 6mm, length 20mm, wall thickness 3mm); non-standard customization (e.g., adjusting thread parameters, material) is supported. Please contact customer service for details.
| Nominal Thread Diameter (M) | Nominal Length (L, mm) | Wall Thickness (t, mm) | Internal Thread Type |
| M3 | 10-30 | 1.0-2.0 | Metric Fine Thread (P=0.5) |
| M4 | 12-40 | 1.5-2.5 | Metric Fine Thread (P=0.7) |
| M5 | 15-50 | 2.0-3.0 | Metric Fine Thread (P=0.8) |
| M6 | 18-60 | 2.5-3.5 | Metric Fine Thread (P=1.0) |
| M8 | 20-80 | 3.0-4.0 | Metric Fine Thread (P=1.25) |
| M10 | 25-100 | 4.0-5.0 | Metric Fine Thread (P=1.5) |

Product Feature
1. Premium Material, Durable & Reliable:
Made of 304 stainless steel (containing chromium and nickel), it offers excellent corrosion resistance and oxidation resistance (e.g., against moisture, acid, alkali, and salt spray). It remains stable even in harsh environments, with a service life 2-3 times longer than ordinary carbon steel sleeves.
2. Precision Craftsmanship, Secure Fastening:
Threads are precision-machined by CNC lathes + thread rolling machines, featuring deep tooth profiles and uniform pitch (error ≤0.02mm). It mates tightly with bolts (IT6 grade), preventing stripping and ensuring reliable fixation.
3. Diverse Specifications, Convenient Selection:
Multiple common specifications (M3-M12) are available, covering home decoration, industrial building materials, medical equipment, and other fields, reducing customer selection costs. Non-standard customization (e.g., adjusting size, material) is supported to meet personalized needs.
4. Customization Service, Flexible & Efficient:
As a source manufacturer, we have complete non-standard customization capabilities (e.g., adjusting wall thickness, length, thread parameters). We can quickly produce according to customer needs, with a short delivery cycle (3-5 days for conventional specifications, 7-10 days for non-standard ones).
Application Fields
- Home Decoration: Used for assembling furniture (e.g., sofas, wardrobes, bookshelves) to fix connectors (e.g., hinges, slides, shelf brackets), maintaining stable furniture structure and preventing damage caused by loose parts.
- Industrial Building Materials: Used for connections in steel structure buildings, scaffolding, and railway facilities, withstanding heavy loads and vibration to prevent part displacement and ensure structural safety.
- Medical Equipment: Used for fixing parts of medical devices (e.g., operating tables, imaging equipment, rehabilitation devices), complying with medical hygiene requirements (no harmful substance leaching) and ensuring stable device operation.
- Food Industry: Used for assembling food processing machinery (e.g., packaging machines, conveyor lines, mixers), with corrosion resistance (against food raw material erosion) and easy cleaning (complying with GB 14930.1 food-grade standards) to avoid food contamination.
- Vehicle & Ship Parts: Used for fixing engine components (e.g., cylinder heads, camshafts, crankshafts) and chassis parts (e.g., suspension brackets, drive shafts) in automobiles/ships, withstanding vibration and impact to ensure operating stability.
- Communications Industry: Used for fixing internal parts of communication equipment (e.g., base stations, switches, routers), with high precision (IT6 grade) to ensure no part loosening and no impact on device performance.
