PrecisionGeek are very proud that our stainless steel and aluminum fittings are all made in-house on our own Star CNC Machines. From speaker spikes through RC parts to banjo bolts — everything is machined from solid stainless steel and other quality grade metals to exact specifications meaning that quality control is maintained throughout the manufacturing process. It means we can react to new demands, improve and assess each component and offer the best quality solution to any requirement. It also means that we can react to new products required immediately — If you feel there is a new product which we could add to our catalogue please get in touch and we will be happy to offer a quotation. All manufactured in the EU on our own machinery — It's very rare today when many items are simply bought in. We are a company that actually cuts its own metal in-house.
