About the Bow nut high tensile - whitworth thread

Although the Whitworth standards to which the thread form of these high tensile bow nuts are made dates back to the 19th century, it is still commonly used today, even in the metric era. Thankfully you can still get metric measurements for dimensions of each nut in this range, along with safe working loads expressed in metric tonnes. These start at 0.25 tonne and reach 4.75 tonnes, so for light to mid-duty lifting tasks these bow nuts are suitable. 

The steel used to produce these bow nuts is very tough, taking more punishment and providing improved safety when compared with cheaper alternatives. It is not completely immune to breakages, but the minimum breaking load is five times greater than the rated SWL, which should alleviate any concerns, so long as you pick the right unit. 

Durability & Alternatives

The sturdiness of these high tensile steel BSW bow nuts is impressive on its own, so if you want to add to the lifespan then you might consider specifying the addition of zinc plating for these anchor points. Alternatively you could choose our corrosion-resistant stainless steel eye nuts or check out our full eye bolt family for a multitude of impactful options. 

These attachments might be the final thing you need to buy for your lifting assembly, but what if you are starting from scratch? In that case a made to measure crane or gantry system might be worth selecting from our extensive lifting equipment range. We also supply hoists and hosting equipment from internationally respected brands. Search our site and see just how many different products we can supply.
