A4 Stainless Steel Nuts

The main function of slotted round nuts is to hold parts that do not require any specific preload force. Designed to be tightened with a flat head screwdriver and used in low stress situations. The round shape is aesthetically pleasing, but they can also be easily recessed into a surface to give a clean, flush finish. Slotted Round Nuts are used in a wide range of applications for electrical engineering and machine construction. DIN 546 applies to slotted round nuts, with sizes from M1 to M20.

Hex nuts manufactured to DIN 936 are a low type hex nut. Their height is between a full nut (DIN 934) and a thin/half nut (DIN 439). They can also be known as thin nuts or jam nuts and are often used in conjunction with other nuts as a lock nut. The slim flat profile of these hex nuts makes them useful where space is limited or where there is only a few threads of a bolt to engage with.

Hexagon full nut to DIN standard 934 with standard metric coarse pitch. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assemblies throughout the world. Can be used in conjunction with Hexagon Thin nuts in a "locking" formation for a more secure fitment. Fine pitch and left hand thread variants are also available immediately below this item. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Prevailing torque type nut manufactured to DIN 985. Popularly employed Hexagon nut incorporating a nylon insert to help prevent loosening when fitted. This is the standard profile variant (Type T), a higher profile option is available under DIN 982 (Type P). Typically fitted with a spanner or ratchet with socket.

Prevailing torque type nut manufactured to DIN 982. Hexagon nut incorporating a nylon insert to help prevent loosening when fitted. This is the higher profile (Type P) variant with more available thread engagement and is typically fitted with a spanner or ratchet with socket. A lower profile, where perhaps space is at a premium is also available under DIN 985 (Type T).

A popular nut used in applications where aesthetics are important, giving an attractive look. Domed end also ensures a smooth snag-free finish protecting both the fixing and any foreign body that may come into contact . Also known as an Acorn Nut, these nuts are manufactured to DIN 1587. Also available with a Nyloc insert to DIN 986. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Nut conforming to DIN 439. Also known as a half nut, thin nut, or jam/lock nut. Typically fitted with a spanner or ratchet with socket, often used in pairs or in conjunction with a hexagon full nut in a locking arrangement. A popular nut type, and used for decades on all types of assembly throughout the world. Fine Pitch and Left Hand Thread variants are also available immediately below this item.

Slotted or split beam type hexagon all metal locking nut . 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.

An hexagon nut with incorporated flange, to DIN 6923. 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. A non-serrated variant is also available.

Hexagon Coupling Nuts also known as a long nut, these DIN 6334 connector nuts are typically employed in joining sections of threaded bar/studding together where required.

Prevailing Torque Nuts are a type of all metal locking nut. Designed to lock and resist vibration or shock. Part of the top threads on the nut deform to create a locking action by increased friction, meaning they will not spin freely and torque via a spanner would be needed to fit and remove - hence the name Prevailing Torque. Ideal for applications that require protection against vibratory and other equally dynamic forces. Being All Metal, they do not suffer adversely from high temperatures or chemical contact like other materials such as plastic (used in Nyloc Nuts). Used frequently in Farming Machinery, Automotive and Production Processes.

Compared to standard hex nuts, square nuts have a greater surface contact with the part being fastened, and therefore provide greater resistance to loosening. They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Manufactured to DIN 557.

Counter Nut also known as a Pal Nut, are a stamped nuts made from sheet metal. They are designed to fit over a normal nut and lock it into place by using a series of protruding flanges that grip the host nut securely. Mainly used in conjunction with a standard hexagon nut. Manufactured to DIN 7967.

Popularly employed where frequent hand tightening and untightening of joints is required. To the German Form with slightly larger, rounded wings. To DIN 315. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Hexagon full nut with standard metric coarse pitch, but with a Left Handed Thread. To DIN 934. Can only be used in conjunction with Left Hand Thread screws and bolts.

Hexagon thin, jam, locking or half nut with standard metric coarse pitch, but with a Left Handed Thread. To DIN 439. Only for use in conjunction with Left Handed Thread bolts or screws.

Fine Pitch Threaded hexagon full nut to DIN standard 934. Typically fitted with a spanner or ratchet with socket. The significantly more unusual Fine Pitch variant of the standard Coarse Pitch hex nut for use where more thread engagement is desired. Only for use in conjunction with a matching Fine Thread Pitch bolts or screws.

Nut conforming to DIN 439 but with Fine Thread Pitch. Also known as a half nut, thin nut, or jam/lock nut. Typically fitted with a spanner or ratchet with socket, often used in pairs in a nut locking arrangement. A popular nut type, with a more unusual Fine Thread Pitch for when more thread engagement is required. Must be used in conjunction with the appropriate Fine Thread Pitch bolts or screws.

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.

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.
