Lightweighting Designs

Automotive Lightweighting and Manufacturing Solutions

Today’s technology presses for ideas to reduce the weight of all consumer goods. From automobiles needing greater fuel efficiency to evaluating different assembly methods for alternative materials that lead to a less costly, product-friendly experience - the focus is falling increasingly on fasteners to help achieve these goals.

Semblex is committed to helping achieve accurate results by offering a wide range of fasteners. The following recommendations represent how the correct fastener selection can provide breakthrough assembly methods when meeting weight reduction requirements.

Please get in touch with Semblex for engineering assistance and consultation regarding your application needs.

Light MetalLight Metals

Most commercial light-weighting efforts focus on replacing steel with lighter metals such as Aluminum, Magnesium, and Zinc. These fasteners are designed to provide maximum performance and repeatability in these particular materials.

Thin Sheet MetalThin Sheet

Sheet metal can replace heavier cast components. However, due to the small material thickness, special fasteners are needed to provide adequate thread engagement.

High Strength SteelHigh Strength Steel

High Strength Steels can be used for lightweighting yet provide additional consumer safety protection.  Historically, harder steels presented challenges in being able to use a thread-rolling screw.

Performance Plastic FasteningPerformance Plastic Fastening

Traditional plastic fasteners are inefficient and require more material in the screw and boss. These higher-performance fasteners allow design changes for shorter screws and smaller bosses.

Removing Locking HardwareRemoving Locking Hardware

Many solutions for preventing fastener loosening involve adding hardware such as lock washers, lock nuts, brass inserts, and applied patches. Lighter fasteners can often replace these.



Head HeightReducing Head Material

Traditional internal and external hex drives require excessive wrenching height, resulting in tall head designs.  Using new drive technologies, we can reduce head heights and weight without compromising installation performance.
