Fiberglass pin

Fiberglass pins are cylindrical rods made from continuous E-glass fibers embedded in thermosetting resin, designed for mechanical fastening and structural reinforcement in non-metallic applications. These pins are manufactured through pultrusion, resulting in high tensile strength and low thermal conductivity. Typical diameters range from 3mm to 12mm, with lengths from 20mm to 200mm, and they are available in straight or custom-cut forms. The material composition is E-glass with unsaturated polyester or vinyl ester resin, providing corrosion resistance and electrical insulation.

The pins exhibit tensile strengths between 400 MPa and 700 MPa, depending on fiber orientation and resin formulation. They are non-conductive, non-magnetic, and resistant to moisture, salt spray, and most solvents, making them suitable for marine, chemical, and electronics environments. Unlike metal pins, they do not rust or create interference in sensitive equipment. Surface finish is typically smooth, with no burrs or flash, and they are produced to tight dimensional tolerances of ±0.1mm for precision applications.

These pins are used in textile machinery to guide threads, in construction for non-metallic anchors, in automotive for interior trim fastening, and in electronics for PCB alignment. Buyers include manufacturers of industrial equipment, textile machinery, and aerospace components. Packaging is in sealed plastic tubes or bulk boxes, with quantities per package ranging from 500 to 5,000 pins. Trade terms are typically FOB Qingdao, with payment by T/T or L/C. Lead time is 10 to 25 days after order confirmation.
