Top 10 Tips to Cut the Cost of Fasteners

(1)  Use Standard Design Fasteners Wherever Possible

Standard fasteners are more widely available, cost-effective, and quicker to procure than custom options. Using standard designs can also streamline production and reduce lead times.

(2)  Minimize Variety of Types and Sizes
Reducing the variety of fastener types and sizes simplifies inventory management, lowers procurement and tooling costs, and minimizes the expense of small quantity orders. Standardization reduces SKUs and enhances operational efficiency.

(3)  Specify ANSI Standard Tolerances
Use ANSI tolerances for cost-effective designs. For example, allow radii instead of sharp corners to reduce machining costs. Simplified tolerances improve manufacturability and reduce production expenses.

(4)  Adopt Class 2A and 2B for Inch and 6g and 6H for Metric Thread Tolerances
Class 2A external threads paired with Class 2B internal threads provide a general-purpose fit, ensuring easy installation and minimal driving difficulties. This combination also reduces plating buildup, further cutting costs.  If metric, use 6H (internal thread) and 6g (external thread).

(5)  Incorporate Thread Forming Screws to Eliminate Tapped Holes
Thread-forming screws are an excellent choice for cutting costs, as they form threads directly in the material, eliminating the need for pre-tapped holes. This reduces labor, tooling, and machining costs while ensuring secure fastening. Thread-forming screws also improve joint strength and reduce installation time, making them a valuable solution for cost-conscious designs.

(6)  Choose Cold-Headed Fasteners
Cold-headed fasteners offer increased shear strength and reduce material waste compared to screw machine parts. They also provide a wider selection of head designs, enabling cost-effective solutions for various applications.

(7)  Select Cost-Effective Materials
Opt for low-carbon steel whenever possible to minimize costs. For higher strength in smaller sizes, use heat-treated fasteners, which reduce size, weight, and material expenses without compromising performance.

(8)  Use Multi-Function Fasteners
Fasteners like Sems® Screws, Self-Drillers, and Keps® Nuts can perform multiple functions, such as replacing assembly operations or additional components. This approach increases production efficiency, reduces rejections, and lowers overall costs.

(9)  Avoid Custom Fasteners
Standard fasteners are significantly more affordable, readily available, and offer better delivery timelines. Only consider custom options if no standard fastener can meet your application needs.

(10)  Optimize Coatings and Corrosion Resistance
Use plated or phosphate-coated fasteners instead of expensive solid materials to address corrosive environments. Exceptions may include extreme conditions, such as food processing or marine applications, where specialized materials are necessary.

Bonus Tip:
Focus on "in-place" costs rather than just the purchase price of a fastener. This includes labor for preparation, installation, and downtime or replacement costs. Standardization, material selection, and supplier collaboration can significantly reduce the total cost of fasteners while maintaining quality and performance.
