Ⅱ: Explore Custom Fastener Production and PRIME’s Expertise
Whether you're new to custom metal fasteners or seeking to improve your supply chain reliability, this section offers a comprehensive look into how PRIME designs and manufactures precision fastening solutions. We’ll walk you through key production processes, fastener types, and how our advanced manufacturing systems solve common challenges — from high-tensile performance and corrosion resistance to dimensional accuracy and scalable production.
What is a fastener? Engineered for connection and strength
Fasteners are essential components that mechanically join two or more parts without permanent deformation. From structural bolts and nuts to micro screws and rivets, these parts must deliver consistency, strength, and reliability under stress. At PRIME, our customized fasteners are designed for diverse mechanical loads, finishes, thread forms, and materials — enabling superior performance in every connection.
Fastening Solutions Tailored to Your Application
Every industry and assembly has unique fastening demands. At PRIME, we evaluate your part geometry, load-bearing requirements, and assembly method to propose the most suitable fastener type and production method. Below are our core manufacturing techniques for custom fasteners:
1. Cold Heading: Precision forming at high speed
Cold heading forms the fastener head and body at room temperature using high-pressure dies. This process is ideal for bolts, screws, rivets, and pins — offering excellent material utilization, work hardening, and strength without cutting. PRIME’s multi-die header machines operate at up to 200 strokes/min, delivering fasteners with superior grain flow and dimensional consistency.
2. Thread Rolling: Durable threads without cutting
Thread rolling displaces material to create threads instead of cutting them, improving fatigue strength and surface quality. It is widely used for screws, bolts, and threaded rods where high precision and load distribution are essential. PRIME employs precision flat-die and cylindrical-die systems to create uniform threads that meet international standards like ISO, UNC, and DIN.
3. CNC Machining: Complex geometries with high precision
CNC machining is used for specialized fasteners requiring tight tolerances, complex geometries, or limited production volumes. It enables precision drilling, milling, slotting, and countersinking on various materials. Our CNC department supports prototyping, toolmaking, and production of non-standard fasteners for critical aerospace, medical, and industrial assemblies.
4. Surface Finishing: Protection and performance
Surface treatment enhances corrosion resistance, aesthetic finish, and mechanical performance of fasteners. We offer zinc plating, nickel, black oxide, Dacromet, anodizing, and more — with RoHS/REACH compliance. PRIME’s automated surface lines ensure uniform coating thickness and adhesion while maintaining full traceability and batch control.
Advice for Smart Buyers
To optimize price and lead time, please provide detailed part drawings, annual quantity estimates, coating requirements, and tolerance levels early in the sourcing process. PRIME’s team will help you identify the most efficient production route and quality plan — ensuring your fasteners meet both technical and commercial targets.
Ⅲ: Material Selection Guide — Ensuring Strength in Custom Fasteners
Material selection is a critical factor in the strength, corrosion resistance, and functional reliability of custom metal fasteners. At PRIME, we offer in-depth knowledge of industrial material grades and help our clients choose the best match for their load-bearing, environmental, and assembly requirements. Whether you need high-tensile bolts, corrosion-resistant screws, or lightweight threaded inserts, we help you balance mechanical performance, manufacturability, and cost-effectiveness.
Common Fastener Materials and Their Characteristics
| Material | Tensile Strength (MPa) | Corrosion Resistance | Machinability | Typical Use |
|---|---|---|---|---|
| Carbon Steel Grade 8.8 | 800–830 | Low (requires coating) | Excellent | Heavy-duty bolts, structural fasteners |
| Stainless Steel 304 | 515–750 | Excellent | Fair | Outdoor screws, marine fasteners |
| Brass C36000 | 345–450 | Good | Excellent | Decorative screws, electrical terminals |
| Alloy Steel 4140 (Heat Treated) | 900–1100 | Moderate (with coating) | Good | High-strength bolts, tooling fasteners |
| Aluminum 7075-T6 | 570–640 | Moderate | Fair | Lightweight aerospace fasteners |
How PRIME Supports Fastener Material Selection
From prototyping to full production, our team ensures you get the right material for your fasteners by evaluating mechanical loads, working environment, assembly methods, and international standards.
Certified Raw Materials & Full Traceability
Every batch of fasteners is traceable with supporting MTCs (Material Test Certificates), including tensile, hardness, and chemical data. This documentation ensures compliance with ASTM, DIN, or ISO fastener standards.
Design for Manufacturability (DFM)
We guide clients in selecting suitable materials for thread rolling, head forming, and plating compatibility. Our DFM support ensures your fasteners are both cost-effective and high-performing in end-use conditions.
Cost & Lifecycle Optimization
PRIME helps you compare not just raw material prices, but also performance over time. We account for plating life, vibration resistance, torque retention, and total cost of ownership — making your sourcing smarter and more profitable.
Ⅳ: Surface Treatments for Fasteners — Functional & Protective Finishes
Surface treatment is essential to ensure long-term performance and corrosion resistance in custom fasteners. At PRIME, we apply industry-grade finishing processes tailored to your application needs — from outdoor durability to electrical conductivity — all compliant with global standards.
- Zinc Plating (Cr3+): Thin but effective corrosion protection with optional color passivation.
- Hot-Dip Galvanizing: Thick 80–100μm zinc layer ideal for heavy-duty and outdoor assemblies.
