EV Fasteners and Components

As the leading global industrial fastener distributor and service provider, Optimas has over 100 years’ experience supplying fasteners and components to automotive OEMs and Tier 1s, and is a major manufacturer and supplier to the EV industry.

Whether you need parts for a chassis, drive system, battery mounting (with additional thermal/conductivity demands) or a more robust solution with protection against environmental factors and the demands of an external application, we’re sure to have a high-quality fastening solution to meet your requirements.

Our fasteners and components are available in a wide range of sizes, materials and finishes. In addition, as a full service provider and manufacturing partner, Optimas can provide you with a cutting-edge inventory management system that will increase efficiency, drastically reduce reordering time, and ensure that stock is delivered on time, every time… leaving you to concentrate on what you do best.

The world of automotive and EV construction, from vehicles to infrastructure, is a minefield of technical performance challenges, including the very smallest of parts.

Performance is key, even down to the nuts and bolts that fasten the vehicles together. Light weighting, insulation and material choice are considerations that carry more importance than ever before, directly affecting vehicle performance, range, and overall cost.

EV Manufacturer Fastener Considerations

1. Size

Smaller fasteners can provide opportunities for weight reduction. By decreasing the body diameter of fasteners, the volume of material needed for production is reduced, which can lead to significant weight savings.

3. Geometry

Geometry matters because a shallower head can enable manufacturers to save weight per fastener, leading to significant efficiency gains in aerospace, automotive and other high-end industries.

5. Non-Ferrous

Improve the efficiency of your electrified vehicle or machinery by incorporating non-ferrous, anti-magnetic fasteners that do not interrupt electric current.

2. Insulation

With greater electrification comes a greater need for insulation. Thermal insulation should be considered part of the initial electrical design due to the enormous heat generation inside battery cells.

4. Materials

Much like size and geometry considerations, material selection is key. Using materials like aluminium, magnesium and titanium within the fastener selection process can help reduce weight and increase your distances.

6. Assortment & Availability

It can take up to 56 weeks to get a fastener from one end of the supply chain to the other. EV projects that require specialty fasteners can be even further delayed. Optimas can cut down lead times with a robust portfolio of parts and the buying power to meet the many challenges of your project.

Fastener Manufacturing

Manufactured in our state-of-the-art cold-forming facilities or sourced from our 4000-strong supplier network, Optimas can supply EV fasteners and components for the entirety of your production build.

Our automotive fasteners and components are made from a variety of different materials to prioritse lightweighting and thermal insulation, like plastics, aluminium, and exotic materials like titanium to suit your fastening needs.
