Fasteners for Engine and Transmission

As the leading global industrial fastener distributor and service provider, Optimas has over 100 years’ experience supplying fasteners and components to the automotive industry, and is a major manufacturer and supplier to automotive OEMs, including engine and transmission manufacturers.

From advancements in hybrid technologies to AI-powered cars, the automotive industry is experiencing rapid and monumental changes, including manufacturers of engine and transmission systems. 

Alternative fuels like electricity and hydrogen are currently dominating the market, and these technologies don’t require engines and transmission systems. However, electric vehicles bring with them significant range, heat and lightweighting issues, plus automotive hydrogen technology is still very much in its infancy, meaning more traditional vehicles are still in high demand. 

Nonetheless, in the face of increasingly stringent government sustainability regulations, all manufacturers are expected to improve fuel efficiency and lower the environmental impact of their vehicles, especially those producing diesel and petrol cars. The heavier the vehicle, the less fuel efficient the car is, meaning many manufacturers are turning to engineered, lightweight solutions for their vehicles. Engineering innovation for engine and transmission also remains a key consideration for those manufacturing hybrids. 

Lightweight Fasteners for Engine and Transmission

Engine and transmission manufacturers are revolutionising the design of their builds to lessen their weight, creating lucrative opportunities for engineering innovation. However, it’s important manufacturers don’t lose sight of some of the smallest but most crucial parts in their products – fasteners.  

In some projects engine and transmission fasteners can make up nearly 50% of a Bill of Materials, but may only constitute 1% of a project’s budget. Nonetheless, reducing fastener weight can have a significant impact on the overall weight – and therefore fuel efficiency – of an engine or transmission system. Automotive fasteners should therefore be made of high-quality materials and thoroughly tested before they are put to use in a vehicle application, to avoid impinging on vehicle performance. 

How Optimas Can Help

With over 100 years’ experience supplying automotive OEMs, we can help you drive efficiency across your manufacturing operations.  

Not only do we manufacture and distribute a wide range of standard and specialised fasteners and components across the globe, but our dedicated fastener engineers work with our partners from product design to production line to optimise their products for use.  

With our unparalleled industry expertise, we supply manufacturers of:

  • In-line Engines 
  • W Engines 
  • V-Types 
  • Variable displacement engines (VDEs)   
  • Hybrids


  • Manual Transmission  
  • Intelligent Manual Transmission (IMT)  
  • Automated Manual Transmission (AMT) 
  • Automatic Transmission (AT) 
  • Dual-clutch Transmission systems. 


Alongside manufacturing and distributing fasteners for engine and transmission, it’s our supply chain solutions, engineering services and quality labs that set us apart.

While manufacturing engine and transmission using quality parts is key, to get these parts to a production line its crucial manufacturers maintain a streamlined supply chain 

Enhancing Operations

Our experts can conduct line walks with you and identify opportunities for increased efficiency throughout each stage of your production process, finding ways to remove non-value activities and drive continuous cost savings.

Optimising Inventory

Our OptiTech inventory management solutions ensure products are delivered to the right place at the right time through improved data visibility. This results in improved productivity, cost reduction,  streamlined production, and lowered Total Cost of Ownership (TCO).

Improving Quality

We believe that quality in, is quality out. Evidenced by our range of industry certifications, like ISO 14001 and ISO 9001, Optimas operates its facilities to the most rigorous standards to make sure fasteners for engine and transmission are optimised for use, every time.
