We deliver high quality CNC tapping services for projects where accuracy, compliance and reliability are essential. Our work supports critical infrastructure and high-specification OEM manufacturing, producing precise threaded holes from M6 up to M48 with full certification and quality assurance.
We operate four advanced CNC machines and one plate processing machine, giving us the capacity to deliver precision threads quickly and consistently across a wide range of materials. Our CNC mill tapping process can be combined with profiling and drilling in a single setup, reducing handling, minimising risk of error and shortening lead times. We work with a range of different steels including carbon steels like S355, high-strength steels and weather resistant steels, machining everything from M6 to M48 threads to exact tolerances. Whether you require fine detail work or large structural fixings, our CNC tapping services ensure every component meets your exact specifications.
CNC tapping is the process of cutting threads into pre-drilled holes using computer-controlled machinery. These threads allow bolts, studs and fasteners to be securely fitted, which is vital for the strength, safety and performance of many components. Tapping in CNC machining ensures each thread is accurate, repeatable and consistent, which is critical in industries such as nuclear power, rail, offshore engineering and heavy equipment manufacturing.
With over 35 years of experience, RMP offers a complete service from raw plate to fully tapped components. Our in-house control reduces supply chain risk and ensures consistent quality. We have a proven track record delivering CNC tapping solutions to Tier 1 contractors and meeting the most demanding project requirements.
Every CNC tapping project is delivered to the highest standards. We are certified to UKCA to Execution Class 4 and ISO 9001, providing full quality control and traceability from start to finish. Our threaded holes are produced to meet the inspection and performance requirements of safety-critical industries, ensuring compliance at every stage.
Alongside our specialist CNC tapping services, we provide a full range of CNC machining services to support complex manufacturing projects. These include:
CNC Milling – Precision cutting using computer-controlled rotating tools to shape and finish components to exact specifications.
CNC Drilling – Accurate and consistent creation of cylindrical holes in a wide range of materials.
CNC Tapping – Precision threading for bolts, fasteners, and structural components.
CNC Countersinking – Conical depressions to allow flat-head screws to sit flush for a smooth, secure fit.
CNC Counterboring – Stepped holes for secure seating of bolts or screw heads flush with the surface.
By keeping all these capabilities in-house, we offer a streamlined service that ensures quality, reduces lead times and provides complete control from initial cutting to final finishing.
We work to tight tolerances suitable for both precision and structural applications, in line with your specifications and compliance standards.
