Cage Nuts

Cage Nuts can be applied to square holes, and are commonly found on mounting rails of equipment racks. They offer ideal protection for equipment from stripped threads, and provide handy mounting of server rack equipment.

The combination of a square hole and cage nut is used within rack systems, as this allows for a choice of nut and bolt sizes to be used. If threads are damaged, the metal nut can be easily repleased, as the sheet metal is too thin to tap or thread.

Our Cage Nut range comprises of Steel Cage Nuts that are natural in appearance. A great tool-free option available in M5, M6 and M8 thread sizes.

Cross Dowel Barrel Nuts

A Cross Dowel Nut, also known as a Barrel Nut, is a specialist nut that is commonly used in aerospace and ready-to-assemble furniture applications.

Cross Dowel Nuts and Bolts are used to bolt thin sheet metal parts to bigger components that are often billet or forged. Barrel Nuts are designed for use with Joint Connector Bolts, where a right angle connection is needed.

Our M6 Cross Dowels are supplied in a Zinc Alloy material for a cost-effective solution, whereas the Cross Dowel M8 Nuts are supplied in Steel, for additional strength. The M8 Barrel Nuts are therefore ideal where heavier applications are required - typically on boards of 22mm thickness upwards.

  • Cross Dowel Barrel Nut Sizes: M6 and M8.

Flanged Ball Nuts

Flanged Ball Nuts are an essential component of ball screw assemblies. They are precision mechanical components used in linear motion systems. These nuts, as the name implies, include a flange, which is a flat, projecting rim that extends from the nut and offers additional support and ease of installation.

It's used in conjunction with ball screws to convert rotary motion to linear motion. Ball bearings in the nut roll along the ball screw as it turns, giving smooth and precise linear motion. The flange features a tight tolerance, ensuring minimum backlash and high precision and accuracy.

These are widely utilised in a variety of industrial applications, including in automotive, aerospace, and medical equipment. Please keep in mind that removing the ball nut from the sleeve provided can cause the ball bearings to come loose, rendering the ball nut useless.

  • It is intended for manual or motorised applications at low rotational speeds under load.
  • Extremely durable and have an element of self lubrication.
  • Utilised in a variety of industrial applications, including in automotive, aerospace, and medical equipment.

Hexagon Steel Nuts

Hexagon steel nuts give a solid grip while preventing loosening due to vibration or motion. They are simple to tighten and relax with a normal wrench or pliers. Hexagon steel nuts give a solid grip while preventing loosening due to vibration or motion. They are simple to tighten and relax with a normal wrench or pliers. They are used with steel or stainless steel lead screws for low rotational speeds, manual control, clamping or locking actions, and dead weight reception.

Due to its material, it is used in applications that need high strength and durability but require lubrication to prevent the nut seizing with the screw.

These are widely utilised in a variety of industrial applications, including in automotive, aerospace, and medical equipment. Available as standard right-hand thread hexagon steel nuts as well as left-hand threaded.

Please note: Steel to steel contact surfaces are inappropriate for motorised motion.

Joint Connector Nuts

Joint Connector Nuts, are a joint connector made from zinc plated steel that offers supreme protection against oxidation. The steel connector nut have a hex drive that is suitable for an M5 Allen Key - making then quick and simple to install.

Joint Connector Nuts and Bolts are commonly used in combination to connect and join together component parts, such as wooden assemblies, including flat packed furniture or timber framing.

  • Compatible threads: M6 Joint Connector Nut and M8 Joint Connector Nut.

Lock & Flange Nuts - Metal

A Flange Nut is a type of nut that has a wide flange on one side, which acts as an integrated washer. The washer element helps to evenly distribute the pressure of the nut over the application being secured, thus mitigating the likelihood of damage or the chance of loosening, as a result of an uneven surface.

Our metal nuts offer includes a Flange Metal Lock Nut made from Mild Steel. The Steel Flange Nut has a Zinc finish, and features a notched base for broad support. These flange nuts are sure to limit loosening in an array of applications.
