Custom Long Screw Assembly – 100mm Thread with Anti-Loosening Design for Specialized Applications
As a professional source manufacturer of cnc precision turned components, we specialize in producing custom long screw assemblies. This product is specifically designed for applications requiring manual locking of mechanical components, offering a combination of strength, efficiency, and reliable anti-detachment performance.
Company Strength: Source Factory For Custom Non-Standard Parts
With years of experience in precision hardware manufacturing, we focus on producing non-standard stainless steel and metal machined components.
As a direct factory, we offer:
• Complete in-house production processes
• ISO9001-certified quality control system
• Fast response for drawing-based or sample-based customization
From prototyping to mass production, we provide a one-stop solution for cnc precision turned components.
Key Product Features
1. Premium Material Combination
• Threaded Shaft (Iron Part): Made of 1215 carbon steel, offering excellent machinability and strength, ideal for high-speed thread rolling and smooth thread performance
• Inner Shaft (Component Part): Made of 303 stainless steel, known for corrosion resistance and good machinability
After assembly, the stainless steel shaft is inserted through the carbon steel shaft and mechanically flattened to form a permanent anti-detachment structure.
2. Extended 100mm Thread Length
The long thread provides a wide adjustment range, allowing users to easily tighten and position mechanical components manually.
Ideal for applications requiring flexible adjustment.
3. Anti-Detachment Design – Secure & Reliable
The 303 stainless steel shaft is precisely inserted into the end hole of the carbon steel shaft and then mechanically flattened.
This ensures:
• Permanent fixation
• No loosening under vibration or load
• Long-term operational reliability
4. High-Efficiency Thread Rolling Process
Threads are formed using a thread rolling machine in one pass, offering:
• Higher thread strength
• Smoother surface finish
• Better durability compared to cutting
Each batch is tested using 6g thread ring gauges to ensure thread compatibility and interchangeability for smooth assembly.
This long screw assembly is widely used in:
Adjustment handles and locking mechanisms in industrial equipment
Fitness equipment component adjustment
Tooling and fixture positioning in automated production lines
Woodworking machinery and specialized equipment assembly
Surface Treatment & Customization Options
To meet different environmental requirements, we offer multiple surface treatments:
• Zinc plating (standard)
• Nickel plating
• Black oxide
• Zinc-nickel alloy
Custom finishes are available based on your corrosion resistance and appearance requirements.
Packaging & Delivery
• Standard packaging: PE bags + cartons
• Ensures safe transportation without damage
• Fast lead times with stable quality delivery
