Superior Engineering Advantages

Enhanced Thread Strength with Superior Load Distribution

The M8 female thread provides significantly greater connection strength compared to standard M6 options, while the extended 23mm base delivers superior load distribution across a larger surface area. This powerful combination makes the F2B23/F2S23 particularly valuable for applications requiring both high-strength connections and optimal stress management.

Material Options for Environmental Requirements

Available in both standard stainless steel (F2B23) and marine-grade 316 stainless steel (F2S23), these fasteners can be matched to specific environmental conditions. The F2S23 variant provides superior corrosion resistance for marine, chemical, and outdoor applications where exposure to harsh conditions is expected alongside high load requirements.

Complete Material Preservation

Like all BigHead fasteners, the F2B23/F2S23 preserves the complete structural properties of materials through its adhesive bonding design without requiring drilling. This is particularly valuable for:

• Composite materials where drilling causes delamination
• Thin panels requiring enhanced connection strength with load distribution
• Pre-finished surfaces where penetration would damage aesthetics
• Pressure vessels or sealed containers requiring integrity
• Materials where stress concentration from drilling would create failure points

Superior Vibration Resistance

The combination of adhesive bonding and the extended base design provides excellent resistance to vibration loosening. This ensures reliable long-term performance in applications subject to movement, vibration, or dynamic loading where conventional threaded fasteners would loosen over time.

Aesthetic Finishing

For applications where appearance matters, the F2B23/F2S23 enables completely clean, uninterrupted surfaces on the opposite side of the mounted material. With no exposed bolt heads or rivets, it delivers a professional, seamless appearance ideal for visible surfaces and premium applications.

Professional Installation Guidelines

To achieve optimal results with the BigHead F2B23/F2S23 Female Threaded Collar:

• 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
• Thread Protection: Protect threads from adhesive contamination during installation
• Positioning: Ensure accurate positioning before adhesive curing for optimal alignment
• Curing Conditions: Follow recommended curing times and temperature requirements for selected adhesive
• Load Analysis: Verify the fastener specifications meet your specific engineering requirements, particularly regarding the enhanced M8 thread capacity and extended base load distribution
