Info
Master-Plate® bonding fasteners are available in a combination of base plate styles, in stud, standoff and nut
configurations.
Master-Plate is a cost effective, secure and reliable method of integrating male or female threads into composite,
fibreglass, laminate and carbon fibre applications.
Suitable for surface bonding using adhesive or embedding during the forming process, Master-Plate is ideal for
composites, fibreglass, carbon fibre, moulding compounds, plastics, laminated timber, stone etc.
Available in standard sizes, in thread sizes M4 - M8 for studs and M4 - M10 for standoffs and nuts, in zinc plated
steel and 316 stainless steel.
Custom base plate, fastener type, thread / body lengths can be produced to order.

Please refer to adhesive manufacturer specifications for guidance.
Prepare the panel surface by
cleaning thoroughly with IPA.
Ensuring the adhesive is fully
mixed, dispense sufficient
adhesive for the application.
Locate the Master-Plate
fastener over the adhesive.
Firmly press the Master-Plate
fastener into the adhesive until
adhesive flows through the
holes in the base plate.
Following the adhesive
manufacturers instructions,
allow sufficient curing time.
Once the adhesive is fully
cured, the Master-Plate
fastener is ready for use.
Alternatively Master-Plate fasteners can be embedded directly during the composite moulding process.
