Read MoreWe’ve recently completed the manufacturing of custom 316 stainless steel threaded rods, featuring a precision-engineered tapered body design.
The tapered profile represents a sophisticated approach to load management, in critical fastening applications. Unlike conventional parallel body threaded rods, the graduated diameter provides progressive load distribution along the fastener’s length. Significantly reducing stress concentrations, whilst maintaining full thread engagement at critical connection points. This design methodology is particularly valuable in applications subject to dynamic loading, thermal cycling, or extreme environmental conditions.
Precision Manufacturing Process
This project exemplifies our capability in translating complex engineering specifications into precision-manufactured fasteners. From initial design consultation and technical review, through to CNC machining and precision thread rolling, each stage is carefully controlled to ensure consistent quality outcomes.
The tapered profile requires specialist machining techniques to maintain accurate angular tolerances whilst preserving thread integrity across the varying diameter. Our team of expert machinists utilise advanced CNC turning centres with live tooling capability, enabling a completion of complex geometries in a single setup. Reducing handling, improving concentricity and ensuring dimensional consistency across the entire production batch.
Thread rolling, rather than thread cutting, is employed wherever possible to enhance fatigue resistance through grain flow alignment and work-hardening of the surface layer. This manufacturing approach significantly improves the mechanical performance of threaded components subject to cyclic loading.
Our Commitment to Excellence
Our commitment extends beyond manufacturing capability. We work closely with design engineers, procurement teams and project managers to ensure fastener specifications align with application requirements.
From technical consultation to final delivery, we strive to ensure every customer receives consistent quality, complete reliability, and the confidence that their fastening solutions are engineered to perform under pressure – all in RAPID time!
Whether you’re specifying components for a unique engineering challenge or require volume production of specialist fasteners. Our manufacturing capability and technical expertise will support your project requirements from concept through to completion.
Our team are ready to assist.

Read MoreIn the world of electrical component manufacturing, precision is paramount. One exemplary product showcasing this dedication to exactitude is the brass fitting with M20 x 1.5 internal pitch and PG13.5 external pitch. A specialist component engineered to meet the demands of contemporary electrical installations.
Dual-pitch engineering excellence
This particular brass fitting represents a sophisticated solution to a common industrial challenges. To achieve a secure, reliable connection in electrical assemblies. The component features two distinct thread specifications working in harmony. The M20 x 1.5 internal thread provides a metric standard connection, whilst the PG13.5 external thread offers compatibility with the widely used Panzergewinde (armoured thread) system, originally developed for protecting electrical cables in demanding environments.
The requirement for two precise pitches in a single component demonstrates the complexity of modern electrical engineering. Each thread must be manufactured to exacting tolerances to ensure proper mating, environmental sealing and long-term reliability. This dual-pitch configuration allows the fitting to serve as an adaptor between different threading systems, facilitating versatile installations across various electrical applications.
Why brass remains the material of choice
Brass continues to be favoured for such precision components, due to its unique combination of properties. The alloy offers excellent machinability, allowing for the accurate thread cutting required in dual-pitch fittings. Its natural corrosion resistance ensures longevity in diverse environmental conditions, whilst its electrical conductivity and non-magnetic properties make it ideal for electrical applications. Additionally, brass fittings provide a superior aesthetic finish compared to many alternatives, with the warm golden hue being instantly recognisable in industrial settings.
An ancient material with modern applications
The use of brass in precision engineering connects us to a remarkable historical legacy. The Romans were amongst the first civilisations to intentionally produce brass through a process known as cementation. In this ancient technique, copper was heated alongside zinc ore (calamine), allowing zinc vapour to diffuse into the copper and create the brass alloy.
Roman metallurgists crafted this versatile material into an impressive array of items, including coins that circulated throughout the empire, decorative objects that adorned villas and public spaces, and military signalling instruments such as the distinctive Roman trumpet. These early applications demonstrated brass’s workability and durability. Qualities that continue to make it indispensable in modern manufacturing.
From ancient forges to modern workshops
The journey from Roman cementation furnaces to today’s precision-machined electrical fittings illustrates the enduring value of brass. Whilst modern manufacturing employs computer numerical control (CNC) machining, advanced quality assurance systems, and metallurgical science far beyond Roman capabilities, the fundamental appeal of brass remains unchanged. It is a material that combines strength, workability, and resistance to the elements.
Today’s brass fittings, such as the M20 x 1.5 / PG13.5 component, may be worlds apart from Roman coins and trumpets in their application, yet they share a common thread. The recognition that brass offers an optimal balance of properties for precision work.
As electrical systems grow ever more sophisticated, and as industries demand components that meet increasingly stringent standards, it is fitting that brass continues to play a vital role, bridging millennia of metalworking tradition with cutting-edge engineering requirements.
If you’re looking for a bespoke brass component, our team are ready to assist.
Read MoreIn the demanding worlds of automotive and aerospace engineering, where reliability can mean the difference between success and catastrophic failure, fastener selection is far from trivial.
We are proud to highlight our precision-manufactured 5/16 x 24 UNF spline bolts, engineered specifically for applications where high vibration, extreme loads and long-term durability are paramount.
