Superior Strength and DurabilityBuilt from high tensile steel and subjected to rigorous heat treatment and testing, these double ended studs with collar nuts provide exceptional mechanical strength, enduring working loads of up to 20 metric tons. Their robust construction ensures a long working life and silent, maintenance-free operation, making them ideal for tough industrial and automotive environments.
Precision Engineering and VersatilityConforming to DIN 939/976 and ISO 898-1 standards, these fasteners are designed for versatility across various machinery, flanges, and manifold connections. Their double ended, threaded design with pre-lubricated threads ensures reliable and quick assembly in trucks, trailers, and heavy equipment, adapting to both fine and coarse metric thread requirements.
Quality, Testing, and CustomizationEvery stud and collar nut undergoes 100% quality control for thread accuracy and hardness. Surface treatments like zinc plating and black oxide coating deliver corrosion resistance, while custom size production (M8-M36, lengths up to 300mm) supports specialized application needs. Reliable supply is assured with a monthly capacity of 100,000 pieces and diverse export packaging options.
FAQ's of Double Ended Stud With Collar Nuts:
Q: How are double ended studs with collar nuts typically used in automotive and industrial equipment?
A: These studs securely join flanges, manifolds, and assemblies in vehicles, heavy machinery, and industrial systems. Their double-ended threaded design allows attachment from both ends, providing a strong, reliable connection that withstands high loads and vibrations.
Q: What are the primary benefits of the collar nut with a hexagonal head?
A: The collar nut with a hexagonal head permits easy tightening using standard tools, ensures uniform load distribution, and minimizes the risk of loosening, contributing to secure and stable mechanical assemblies over extended operational cycles.
Q: Where do these double ended studs with collar nuts find applications?
A: They are widely used in automotive sectors (such as trucks, trailers, and commercial vehicles), heavy machinery, industrial equipment, and wherever high tensile fastening and corrosion resistance are critical requirements.
Q: What quality control measures are in place during production?
A: Every piece is subjected to 100% thread inspection and hardness testing. The production process includes heat treatment and cold forging to enhance mechanical properties, along with surface treatments for lasting corrosion resistance.
Q: How do surface treatments like zinc plating and black oxide coating enhance product performance?
A: Zinc plating and black oxide coating shield the fasteners from corrosion and environmental factors, extending service life and reliability-even under harsh operational conditions or fluctuating temperatures.
Q: Can I order custom sizes for specific project requirements?
A: Yes, custom sizes within the M8-M36 diameter range and lengths from 50mm to 300mm are available upon request to match unique project needs or specifications.
