Hexagon Thin Lock Nuts

Hexagon thin lock nuts, also known as hex half nuts, are manufactured in A2 stainless steel and BZP (Bright Zinc Plated), all at competitive prices. Half the thickness of the standard full hex nuts, they are another popular nut in use and ideal when space is an issue. Both the A2 stainless steel and the BZP versions offer corrosion resistance. Used within multiple industries, from enthusiastic DIYers to construction and engineering companies.

As with the standard hex nuts, the hex thin lock nuts can be applied with standard spanners and sockets making them very versatile.

What is a hexagon thin lock nut?

Hexagon thin lock nuts, which are also known as hex half nuts, or hex lock nuts are another common nut available and used across numerous industries. Being six sided with an internal thread they are commonly used with a corresponding bolt with a similar thread. The hexagonal shape makes them easy to use with conventional spanners and sockets which adds to their versatility. Being half the height of the full hex nut makes them ideal for use when space is also an issue.

What are the thin lock nuts used for?

The thin lock nut is predominantly used to join various material together in conjunction with a bolt that has the same thread. After the bolt is inserted into the holes made in the material, the nut is then fastened onto the bolt and tightened, resulting in the clamping pressure of the nut and bolt holding the material together. Very similar in use as the full hex nuts but half the depth.

What are the thin lock nuts manufactured from?

The hexagon thin lock nuts are manufactured in A2 stainless steel which offers a high level of corrosion resistance and BZP - (Bright Zinc Plating) steel which is grade 8 steel covered in a bright zinc plating. The BZP nuts offers a medium level of corrosion resistance when compared to the A2 stainless steel but having a thin layer of zinc, the nut will struggle if used outside for long periods of time.

A2 stainless steel lock nuts

A2 grade stainless steel is also referred to as 304 or 18/8 steel, due to the alloy being formed of 18% chromium and 8% nickel. The higher level of chromium helps the alloy resist and prevent further spreading of corrosion and staining that may occur within certain types of applications. Our A2 stainless steel nuts are an excellent choice when a higher level of corrosion resistance is required.

BZP – bright zinc plated lock nuts

Zinc plated passivation is a common finish on steel products within the fixings industry due to its affordable. The layer of zinc provides a galvanized protection to the steel which helps to prevent oxidization. The zinc coating sits on top of the steel and due to the coating only being thin, whilst it does provide resistance to moisture, it will struggle to prevent rusting when used outside for longer periods.
