What Construction and Heavy Equipment Need From Fasteners

When it comes to manufacturing bulldozers, excavators and any other site preparation equipment, safety, reliability and strength are key points for consideration when sourcing fasteners.

Having been in this industry for 70 years, we know a thing or two about sourcing and supplying fasteners. Specifically, sourcing fasteners to distributors serving the manufacturers and repair network of construction and heavy equipment. In this deadline driven world, downtime costs money. Distributors supplying this industry need to rely on wholesale partners for a readily available supply of high quality, specialized fasteners. This is alongside a service mindset to meet the special needs of this demanding industry.

So, what can you do to ensure you are getting the right parts when you need them?

Construction and other heavy-duty applications require strength and durability, namely, because of the scale and weight of the equipment, which puts a certain level of pressure on fasteners. Sourcing these parts can pose challenges as most wholesale distributors will stock smaller diameter, high volume, off-the-shelf sized parts.

At Earnest Machine, we specialise in high strength, hard-to-find, imperial fasteners in Grade 5, Grade 8 and proprietary Grade 9 – 170m strengths. What’s more, Earnest carries imperial fasteners in niche size ranges for distributors supplying the manufacture and maintenance of construction and heavy equipment.

Protecting fasteners from the elements

Construction Equipment and Heavy Machinery is under constant exposure to extreme weather conditions, such as rain, snow and salt. Corrosion is the greatest enemy to fasteners. With this in mind, it’s important to work with a wholesale supplier that knows which specialty plating or coating can help protect fasteners from extreme weather exposure. Earnest Machine has published a Plating and Coating eBook that helps distributors understand and identify the applications for specific plating or coatings.

Specialty parts should always be available

The complex and highly technical nature of construction and heavy equipment means that there are often specialty parts designed into equipment specifications. This means that ‘off the shelf’ or standard items don’t always fit the mould.

In this scenario, you need a supplier that has the resources to find the parts you are having trouble finding. Seek out an industry specialist that can create the product you need based on an engineer’s print specification for a single part. Wholesalers and manufacturers should also be able to source quantities for an entire production run and have resource for specialty materials.

The team at Earnest Machine UK understands the requirements of the Construction and Heavy Equipment market and has the experience and resources to help distributor customers source bespoke parts. Earnest is able to create bespoke fastener solutions and has resources to help distributor customers source bespoke parts. We work directly with design engineers – providing a consultation that delivers the perfect result every time.

Metric and Imperial Fasteners Availability: UK and Europe

Most of us know that metric and imperial are the two measurements used for fastener sizes around the world. While the US market favours imperial measurements, metric fasteners are more widely used in the European market. Metric was introduced to Europe back in the 1700s and has been the official usage in the UK since 1965. However, that doesn’t mean that metric fasteners are the only fasteners used in the UK.

US companies don’t exclusively use metric, as they may have manufacturing facilities across Europe, meaning they use imperial fasteners. In the same way, it’s not guaranteed that Europe-based manufacturers or distributors will only require metric product. The type of fastener used is always decided by the application and instruments used. So, a swap from metric to imperial, or vice versa, would mean a whole redesign of the application. 

Ultimately, at the original concept and production process for a part, either a metric or imperial fastener would have been designed for the application. Earnest, and typically our core customer base, are not the decision makers with regards to what style of fastener can be used or the unit of measurement specified. While we can always look for alternatives, upgrades or new products to the market for consideration, the original engineered part is the go to in the majority of cases.

The differences also go a little beyond the measurement used too, which is always a consideration. The thread flank angles differ between US and European standards. An American standard coarse thread has a 60º flange angle, whereas British standards are at 55º. 

Before we look at demand and availability, let’s recap the basics first…

What is a metric fastener?

While metric clearly refers to the basic unit of measurement, within the world of fasteners, it also represents further information. They are measured diameter, pitch and length in millimeters (mm). 

What is an imperial fastener?

Imperial fastener sizes work in a similar way, but with a different basic unit of measurement. They are measured by diameter and length in inches. Thread sizes range from approximately 6 – 40 tpi (threads per inch). There’s also the consideration of thread pitch, where they are measured by diameter, thread pitch and length. For example, a 1.5 x 8 x 7.25 is 1.5 inch diameter “by” 8 thread pitch by 7.25 inch length.

Like metric fasteners, imperial fasteners are graded by strength. The higher the grade number indicated on the head of the fastener, the stronger the fastener is. Grades available in imperial fasteners are Grade 2, 5, 8, alongside an unofficial 170m strength level sometimes referred to as grade 9.

Metric fasteners UK vs imperial fasteners UK: What is the availability of both in Europe?

Generally speaking, most of the world has (or is in the process of) moving to metric standards. Markets like the US are one of the last to make this change due to the huge and diverse market. This is all down to globalisation of the product and the industrial methods used – which generally conform to metric. While the US market is likely to see heavy usage of imperial for a while to come, a wide range of other markets will see more and more usage of metric. It has also been the most widely available option in the European market for some time. This is because it’s the official unit of measurement in the UK and most of Europe. 

What does Earnest have on offer?

While there are a wide variety of metric fasteners, here at Earnest, we focus on hard to find imperial and metric fasteners. Specifically, we can help distributors build a supply chain of high strength, large diameter, imperial or metric products. These products are seen as niche in the EU and UK markets. When we do stock a metric part, it is because it is a niche item or a non-standard size.

You can expect to find a range of large diameter and high strength fasteners from us. These parts are frequently used in the agriculture, heavy equipment, heavy transportation, mining, oil & gas, robotics and automation industries.

From this specialisation in niche fasteners, we often see requests for non-core products and bespoke fasteners to print. To better serve the needs of our customers, we have formed a Custom Solutions team of fastener experts. This team helps our customers source parts that have special requirements, such as being made from specialty materials or those that don’t have a consistent supply chain established.

Earnest Machines goal is to help customers by delivering the right part, in the right quantity, on time, every time.
