Fastener Manufacturing Process
Advanced hot forging, cold heading, CNC turning & stamping capabilities cover standard to custom fastener production. ISO 9001 certified quality ensures global compliance. One-stop design-to-production service delivers premium, cost-effective fastener solutions worldwide.
Hot forging is a metal forming process performed at elevated temperatures, where heated billets are shaped into desired forms using dies. This process is ideal for manufacturing high-strength, large-size fasteners such as high-tensile bolts and nuts, significantly enhancing material density and mechanical properties to ensure reliability and durability in harsh operating conditions.
Hot forging
Cold heading is a high-speed metal forming process performed at room temperature, where metal wire is shaped into fastener blanks through impact forming without heating. This process offers high production efficiency, excellent material utilization, and superior surface quality, making it ideal for mass production of standard bolts, screws, rivets, and other fasteners, representing the mainstream manufacturing method in modern fastener industry.
Cold heading
Turning and machining processes utilize CNC lathes and machining centers to perform precision cutting operations on metal materials, ideal for manufacturing non-standard fasteners with complex shapes and high precision requirements. This process enables high-accuracy dimensional control and complex geometry machining, particularly suitable for small-batch, multi-variety customized product production to meet specific customer requirements.
Turning
Stamping process utilizes presses and dies to perform cutting, bending, and drawing operations on metal sheets, primarily used for manufacturing flat fasteners such as washers, retaining rings, and spring clips. This process features high production speed, low cost, and excellent consistency, making it suitable for mass production of standardized flat fastener products.

Dimensional Testing
We conduct comprehensive dimensional testing on
We conduct comprehensive dimensional testing on fasteners using precision measuring equipment to verify diameter, length, thread specifications, head dimensions, and other critical geometric parameters. Ensuring compliance with international standards (ISO 4759, ASME B18.2.1) and customer drawings, our advanced tools including calipers, micrometers, thread gauges, projectors, and CMM guarantee precise tolerance control for interchangeability and assembly performance.
Surface Quality Testing
We conduct comprehensive surface quality testing
We conduct comprehensive surface quality testing including visual inspection, roughness measurement, and coating thickness analysis. Using visual examination, microscope analysis, and professional instruments, we identify and control surface defects such as scratches, bubbles, oxidation, and cracks. We also precisely measure coating thickness for plating, blackening, Dacromet, and other surface treatments to ensure corrosion resistance and aesthetic quality, delivering attractive and durable products to our customers.
Mechanical Testing
Tensile, hardness, torque and other tests to verify fastener strength and reliability, ensuring safe performance under various load conditions.
Chemical Analysis
Spectroscopic analysis to precisely measure material element content, ensuring raw materials meet standard requirements and providing fundamental quality assurance.
OUR PARTNER
We can assist by customising fasteners to your specific requirements.
SOLUTIONS TO FIT YOUR EXACT REQUIREMENTS
Our fastener experts will work with you to understand your exact requirements in terms of style, material and dimensions, and commission technical drawings and a prototype at no cost to you.
Once you are satisfied with your bespoke fastener, it will be added to our inventory system and we can then quote and order it for you in any quantity, with repeat orders if required.
ALTERNATIVE SOLUTIONS
With most fasteners being imported in a standardised but limited range of diameters and lengths
you may be struggling to find exactly what you need – that’s where we fit in!
