Bolt Testing

At BES Group, we can help you assess the strength and durability of your fasteners. We test a range of bolts for mechanical, metallurgical and chemical properties from sizes M2 up to M27.

Bolts and nuts are widely used fasteners due to their ease of assembly and disassembly. Ensuring the safety and reliability of machines and equipment, bolt testing plays a vital role. This process guarantees that bolts can endure their designated load and function effectively under various stresses and conditions. By identifying potential failures, it also helps in minimising costs by reducing instances of failures, downtime, and maintenance. Discover more about our comprehensive bolt testing services below.

Independent testing services for your bolts

Fasteners and raw materials for producing fasteners must be routinely tested to ensure that they are suitable to be used in their intended environment. Choosing a UKAS accredited testing laboratory for your bolt testing means that our processes and testing procedures are of the highest quality, giving you confidence in your products, and reassurance that they are fit to be used in real-service conditions.

We test a range of bolts, including:

Anchor bolts
Blind bolts
Carriage bolts
Double end bolts (also called Tap End Studs)
Eye Bolts
Flange bolts
Hex bolts
Machine bolts and machine screws
Socket head bolts, Square head bolts
T-head bolts
U-bolts

And many more!

We can analyse a range of bolts made from different metals.

Bolts must be produced from the right material. If an inappropriate metal or material is used, the bolt may experience fatigue, corrosion, or failure during service.

Most commonly, bolts are made from steel alloys, such as stainless steel, low carbon steel, and chromium as this offers the best protection against corrosion and corrosive environments. To further enhance the performance of steel, bolts may undergo additional treatments such as plating, coating, or galvanization.

Titanium, Cupro Nickel and Aluminium, Inconel are also used to manufacture bolts depending on their end use.

Bolts are commonly made from stainless 18-8 steel, containing 18% chromium and 8% nickel. Another type of steel that is more resistant to corrosion is stainless 316, and is often used in salt water and chlorine environments. Bolts may also be made from stainless 410 material, which is a more durable steel but less resistant to corrosion.

Alloy steel is a high-strength material that can be heat treated to produce durable bolts.
