We’ve found Bon Precision Engineering to be very knowledgeable, helpful and easy to work with.

Excellent service from John and the team at Bon Precision! With the requirement for some bespoke spacers to fit replacement solar panels, I approached John with the dimensions and requirement for the material to be aluminium. He came back with the initial order quickly having invested in specific tooling.They were such a success a further 1100 spacers were requested by our customer for use nationwide. These were manufactured very quickly and efficiently. We also now purchase our stainless fixings and specialist fixings through the Bon Precision team.
