BigHead Female Hex Nuts F1/B23 & F1/S23

Are you working with composites, thin panels, or applications where traditional fasteners create stress points and material failure? The BigHead F1B23/F1S23 Female Hex Nut provides an innovative solution with its large 23mm base for superior load distribution. This professional-grade bonding fastener creates secure female-threaded attachment points without drilling or compromising material integrity, making it ideal for demanding applications across marine, automotive, aerospace, and industrial sectors.

Enhanced Load Distribution with Larger 23mm Base Design

The BigHead F1B23/F1S23 takes load distribution to the next level with its generous 23mm diameter base. This expanded footprint provides approximately 32% more surface area than standard 20mm models, significantly improving load distribution and reducing stress concentration on the substrate material. The larger base makes this model particularly valuable for applications with higher load requirements or more delicate materials where stress distribution is critical.

Superior Engineering Advantages

Enhanced Load Distribution

The expanded 23mm base provides significantly better load distribution compared to smaller base models, reducing stress concentration on the substrate material. This larger footprint makes the F1B23/F1S23 ideal for applications with higher load requirements or materials that demand optimal stress distribution.

Material Options for Environmental Requirements

Available in both standard stainless steel (F1B23) and marine-grade 316 stainless steel (F1S23), these fasteners can be matched to your specific environmental conditions. The F1S23 variant provides superior corrosion resistance for marine, chemical, and outdoor applications where exposure to harsh conditions is expected.

Non-Penetrating Attachment Solution

Unlike traditional fasteners that require drilling, the F1B23/F1S23 preserves the structural integrity of materials through adhesive bonding. This is particularly valuable for:

• Watertight or pressure-sealed containers
• Composite materials where drilling causes delamination
• Thin panels where traditional fasteners lack sufficient grip
• Pre-finished surfaces where penetration would damage aesthetics
• Honeycomb or sandwich materials that collapse when drilled

Female Thread Configuration

The integrated female thread creates a secure, flush mounting point that accepts standard M6 male threaded fasteners. This versatile configuration allows for both permanent installations and components that may need future removal or replacement, providing design flexibility for complex assemblies.

Vibration-Resistant Performance

The combination of adhesive bonding and the large load distribution base makes these fasteners exceptionally resistant to vibration loosening. This provides more reliable long-term performance in applications subject to movement, vibration, or dynamic loading compared to conventional threaded fasteners.

Professional Installation Considerations

To achieve optimal performance with the BigHead F1B23/F1S23 Female Hex Nut:

• Surface Preparation: Ensure bonding surfaces are properly cleaned and prepared according to adhesive manufacturer specifications
• Adhesive Selection: Choose appropriate structural adhesives based on substrate material and application requirements
• Curing Conditions: Follow recommended curing times and temperature requirements for selected adhesive
• Load Analysis: Verify the fastener specifications meet your specific engineering load requirements
• Thread Protection: Protect threads from adhesive contamination during installation
• Material Compatibility: Consider thermal expansion rates and galvanic compatibility in your application

The Engineering Professional's Solution for High-Load Applications

The BigHead F1B23/F1S23 Female Hex Nut represents an advanced fastening solution for engineering professionals facing complex attachment challenges in modern manufacturing.
