For design engineers and sourcing professionals, choosing between standard and custom swaged pins is more than a spec sheet decision—it can make or break your project's cost, performance, and delivery timeline. A poor fit can cause design limitations, premature failures, or increased total cost of ownership.

With over 100 years of swaging expertise, Bead Electronics is here to help you optimize your pin performance with custom, tailored solutions. We understand how to strike the balance between off-the-shelf efficiency and custom-engineered performance. Let’s explore the differences between standard and custom swaged pins to help you decide which is right for you.

Understanding Swaged Pin Fundamentals

Swaging is a precision cold-forming process that reshapes metal without removing material. Instead of cutting or machining, swaging moves metal to form precise geometries.

Bead’s Scrapless Swaging Advantage

Our scrapless swaging process not only improves material efficiency, but also results in:

• Tighter tolerances
• Consistent breakpoints
• Superior electrical performance

This method reduces material waste, which means lower costs, faster production, and a smaller environmental footprint.

Standard Swaged Pins

Ideal for consumer electronics, automotive,  telecom and general-purpose connectors, standard swaged pins are made with existing tooling. These pins are often made with popular materials such as brass, copper, and phosphor bronze with tin, gold, or nickel plating.

Advantages of Standard Pins

Standard swaged pins offer several advantages, such as: 

• Cost-effective: No tooling or design fees
• Available off the shelf: Faster time to market
• Proven reliability: Industry-standard configurations

Limitations

Standard swaged pins may not meet specific performance criteria, such as maintaining optimal performance in harsh demanding environments. With limited flexibility in design and fit, there is potential for over-engineering or underperformance. 

When Standard Pins Excel: If your application is well-defined, high-volume, and falls within typical mechanical or electrical requirements, standard pins offer unmatched value.

Custom Swaged Pins

Customization can range from minor tweaks—like a unique finish or slightly modified length—to completely unique designs tailored for specialized performance.

Bead’s Custom Capabilities

We offer full customization in:

• Base metals: Including specialty alloys for unique environments
• Plating options: Tin-lead, gold flash, nickel, and more
• Geometry: Varying lengths, diameters, and head shapes
• Advanced features: Retention grooves, stepped diameters, swaged tips, and more

Advantages of Custom Swaged Pins

Custom swaged pins offer numerous advantages, such as: 

• Optimized for exact application needs
• Space and weight savings in compact designs
• Enhanced electrical and mechanical performance
• Brand differentiation through proprietary connectors
• Cost benefits over time in high-volume production

The Engineer’s Decision Matrix

To decide between standard and custom, engineers should evaluate:

Performance Requirements

• Electrical: Voltage, current, resistance, signal integrity
• Mechanical: Insertion/withdrawal force, fatigue, retention
• Environmental: Heat, vibration, corrosion resistance
• Longevity: Lifecycle expectations and reliability

Design Constraints

• Board space and layout limitations
• Connector compatibility
• Assembly fit and process alignment
• Tolerance stacking and manufacturability
• Compliance (UL, MIL-SPEC, IPC, etc.)

Economic Considerations

• Upfront tooling vs. per-unit cost
• Production volume and return on investment
• Time-to-market pressure
• Supply chain risk and long-term savings

Manufacturing & Supply Chain Factors

• Forecasted volumes and reorder cycles
• Inventory management strategy
• Preference for domestic sourcing (e.g., Made in USA)
• Supplier responsiveness and engineering support

Bead Electronics: Your Customization Partner

Choosing a custom swaged pin doesn’t have to mean a long lead time or high upfront costs. At Bead Electronics, we offer rapid prototyping for mechanical properties to accelerate design cycles and in-house tooling and engineering for agile development. With flexible MOQs, we can support both low and high-volume needs. Our dedicated technical support team will guide you through the process from concept to production. Plus, by choosing an American manufacturer like Bead, you have tighter supply chain control.

When to Go Custom

If your project demands optimized performance, tight space constraints, or unique functional requirements, custom swaged pins offer a strategic advantage. But if your needs are standard and your timeline is tight, standard pins deliver exceptional value and speed.

Either way, Bead Electronics is here to help you make the best decision, backed by a century of engineering experience and a commitment to quality.
