Imperial Nuts

Hexagon full nut to ASME B18.2.2. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assembly throughout the world.

Hexagon full nut to ASME B18.6.3. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assembly throughout the world.

Nut conforming to ASME B18.2.2. Also known as a half nut, thin nut, or jam nut. Typically fitted with a spanner or ratchet with socket, often used in pairs in a nut locking arrangement. A popular nut type, and used for decades on all types of assembly throughout the world.

Hexagon Machine Screw Nuts (UNC - Unified Coarse Pitch) imported from the USA. These nuts generally have smaller internal diameters than the range available in standard hexagon nuts, so fit the smaller gauge sizes for Imperial screws. They also tend to be thinner or lower in height but have a larger outer diameter. These are specifically designed to be used in conjunction with other UNC screws or bolts. Often used in small electrical goods manufacturing, such as computers and hifi systems.

Slotted or split beam type hexagon all metal locking nut with UNC Thread form . Manufactured in the UK with the Aerotight trademark. Undersize threaded sections on top portion of nut mean that when tightened into position the undersize section is forced outward creating high friction and a more secure 'locked' fitment. A locking nut for use in higher temperatures where a locking nylon ring nut would be unsuitable.

A popular nut used in applications where aesthetics are important. Also known as an Acorn nut, these nuts are manufactured to ASME B18.2.2, in this instance they have a standard Unified Coarse Thread Pitch (UNC). To be used in conjunction with same sized UNC screws and bolts.

Also known as a long nut, these coupling or connector nuts are typically employed in joining sections of threaded bar/studding together where required.

An hexagon nut with incorporated flange. The flange offers protection for the bolted component where the driving tool may otherwise scratch it's surface. The flange also lessens the need to use a washer. This particular version has serrations on the base.

Popularly employed where frequent hand tightening and untightening of joints is required. To ASME B18.6.9.

Larger and thicker variant of a standard hexagon full nut. Generally used with large diameter and high strength bolts, and manufactured to ASME B18.2.2. These nuts are manufacured with a double chamfer (chamfered both sides), but sizes larger than 7/16 will likely include a flat or washer face on one side. Please bear this in mind when ordering.
