Steel Nuts
Nuts and bolts are used to hold together a wide variety of installations and machinery. From manufacturing machinery and storage to the automotive sector and farming, at every turn, there is something that relies on steel nuts and bolts to hold it together or attach it to something else.
Although it's a simple fastening, the nut and bolt is a very effective one, holding together surfaces by combining the friction of the thread, the compression of the parts being fastened, and a slight stretching of the bolt. No wonder they've been around for such a long time and are still in everyday use.
If you're looking for high tensile steel nuts, then Simply Bearings can supply what you need. We stock a wide variety of different sizes, in both metric and imperial measures. To locate what you need, use the drop-down lists at the top of the page, to find the thread size, diameter, flange width and thickness you require. Ordering is as simple as that, but if you need any extra help, our professional, friendly customer services team is always available on the end of the phone and will be happy to assist.
We stock standard type high tensile steel nuts as well as flanged nuts and Nyloc locking nuts, so you should be able to find exactly what you need for any task. All types are zinc-coated, to provide good corrosion resistance and a neat finish.
We can supply both large and small quantities, and if you get your order in before 4pm, it will usually be despatched on the same day. Delivery by second class post is free of charge, but if you need your nuts to arrive more quickly, you can choose first class post or a courier service at the checkout, and the extra cost will be automatically calculated for you. We're happy to supply overseas orders too - again just select your delivery options when you place your order.
As with all Simply Bearings products, these products are covered by our 90-day no-quibble money back guarantee, so you can order with complete confidence.
