How to Install PEM/Aerospace Style Hardware in Sheet Metal

The age-old idiom, “The devil is in the details,” stresses the importance of a thorough completion of any job. In sheet metal production, those details of such an important significance are in sheet metal hardware installation. The sheet metal hardware selected for any job is important because it can greatly impact the overall form, function, and appeal of a product. By understanding the challenges of sheet metal hardware installation and some options to overcome those challenges, sheet metal fabricators are able to finish any custom job with details that even the devil cannot deny.

Hardware Installation Challenges for Sheet Metal

The details of sheet metal hardware can be overwhelming to manage given the high number of challenges associated with sheet metal hardware installation. The challenges for sheet metal hardware installation fall into two general domains: installation and quality. The specific issues with hardware installation for a particular sheet metal project will depend upon the specifics of that job.

Sheet metal hardware installation can be tricky to develop an installation protocol. In sheet metal product fabrication, the hardware installation can be an expensive endeavor because it is often one of the final stages of production. The product is close to finalized when sheet metal hardware is implemented—the risk is great because there is already a great deal of investment in the item. Sheet metal hardware installation can also be an arduous process because it often times involves multiple steps to complete the installation. And each time through the sheet metal hardware installation process is a risk that a mostly completed sheet metal product can be ruined. Professionals understand this challenge for sheet metal hardware and will likely select a sheet metal hardware that is most appropriate for a particular project.

Sheet metal hardware installation also presents challenges in the finish of the hardware. Specifically, sheet metal fabricators struggle with two recurring issues. First, sheet metal hardware can be difficult to install without mistakenly damaging the sheet metal hardware during installation (e.g., missing fasteners or misaligned holes). Professionals are aware of this issue and strive to overcome any challenges with sheet metal hardware. Second, sheet metal hardware installation relies on consistency in installation. Sheet metal fabrication can be a game of millimeters or fractions of an inch. In order for sheet metal products to function and sustain, the hardware that holds it together must be installed exactly right. The devil is truly in these details as sheet metal hardware installers must be precise and consistent.

The challenges to sheet metal hardware installation are great. And these struggles can be quite costly for sheet metal production in time, energy, and money lost to flawed sheet metal hardware installation. Sheet metal operators have developed multiple strategies for overcoming these struggles. The most tangible of these is to implement a style of hardware for sheet metal that is most appropriate for the project at hand. Specifically, two types of sheet metal hardware seem to be successful at minimizing these challenges: PEM style sheet metal hardware and aerospace style sheet metal hardware.

PEM Style Hardware for Sheet Metal

PEM hardware is an ideal sheet metal hardware for projects made with thin, hard surfaces such as automotive manufacturing. This light sheet metal hardware, which can be flush with the product so there are no noticeable seams, can be installed in a single-step permanent press directly into the sheet metal. Because there are no additional steps to sheet metal hardware installation (e.g., embossing or welding), the sheet metal can be pre-finished prior to installation.

How to Install PEM Style Hardware in Sheet Metal

PEM hardware is installed through a process of pressing sheet metal hardware through holes so that the items fit together in a tight hold. PEM style hardware does not require heat (e.g., welding) to maintain the tight hold so there is little risk of destroying a nearly finished sheet metal product during sheet metal hardware installation. PEM style hardware is held in place through any number of variation of self-cinching in which the product is tightened on itself without any additional loose hardware. As the force of the pressure to insert the hardware into each other is exerted, that pressure also seals the items together through sheet metal hardware (e.g., teeth, serrated clinching ring) so that the sheet metal will stay connected. PEM style hardware developers have moved away from threaded style sheet metal hardware because the threads increase the demand for precision and room for error during sheet metal production. And threads in sheet metal hardware can become stripped and lose the grip. These new bonding technologies are more consistent and durable. And made PEM style hardware installation is a smoother process.

Aerospace Style Hardware for Sheet Metal

Aerospace style hardware is a specific style of sheet metal hardware which can be ideal for sheet metal fabrication because of its high strength-to-weight ratio. Aerospace style hardware is also a perfect finish for custom sheet metal fabrication because of the additional demands that this detailed sheet metal hardware can fulfill. Aerospace style hardware is designed to work in extreme environments, high pressures, and for long periods of time. The reliability and durability of this sheet metal hardware provides a strong finish with attention to the details of any job.

How to Install Aerospace Style Hardware in Sheet Metal

Aerospace style hardware is installed in traditional ways with high tech modifications. Generally, aerospace style hardware relies on threaded bits and joints. While traditional in conception, this style of sheet metal hardware is installed in innovative and advanced ways. For example, this sheet metal hardware is often made of composite materials which make it capable of withstanding a number of potential environments. And the tools used for this style of hardware installation (e.g., automated drilling systems or the Flex Track hand held drill) make the precision and consistency necessary for this sheet metal hardware installation a simple task to complete.

Sheet metal hardware installation can be a difficult process with many challenges. But with professional guidance and careful consideration of the particulars for a sheet metal project, sheet metal hardware can be a smooth finish to any sheet metal product. If the devil is in the details, then sheet metal hardware is the perfect weapon for overcoming the specifics of any sheet metal project.
