Our wide range features a vast array of sizes, including large diameter plastic washers that are suitable for a number of metric threads. We also offer a choice of materials, including Nylon washers and other plastic washers made from Polycarbonate (PC), Polypropylene (PP) and Polyoxymethylene (POM). As well as high-quality, hard plastic washers like Polyether Ether Ketone (PEEK). All with a durable, smooth finish.

Machine Screws - Flat

Flat machine screws are characterised by a flat head with no tapering that sits flush with the surface. Typically threaded along the entire shaft length, and can be tightened with a screwdriver. Designed to screw completely into a countersunk hole.

The flat head offers a firm grip and keeps the screw from sliding. It is a durable, aesthetically pleasing fastener with good temperature resistance. It is less likely to damage the surface of the material they are being screwed into than protruding machine screws. Used in applications for furniture, machinery and electrical.

Machine Screws - Mushroom

Machine Screws with a mushroom head are designed for use in a wide range of applications, including machine assembly, woodworking, and construction. Its mushroom head is rounded with a wide bearing surface and a low-profile design. It can be used in applications requiring a low profile, as the head shape allows for a reduced profile compared to other types of screws. It also provides a large bearing surface to distribute the load evenly.

Unlike regular screws, machine screws tend to be more durable and robust, making them perfect for resisting corrosion, high temperatures, and other chemicals or weather conditions. It is commonly used in machine assembly, including electronics, automotive, and industrial applications.

  • Material: PC, Nylon, PA
  • Colour: Clear, Natural, Black, White

Machine Screws - Pan

Slotted, Torx and Crossed (Phillips) style Pan Head Machine Screws that come in standard metric and imperial sizes.

A Pan Head Screw is a great replacement to metal screws. They are lightweight, and offer resistance to vibration, chemical and electrical resistance, and corrosion.

Retaining Washers

A Plastic Retaining Washer is primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. Also known as an Anti Loss Washer, they provide insulation, cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.

This washer range includes options with internal and external teeth with a tapered design. The washer easily slides on to the screw (or bolt) and is retained by the screw once assembled. The washer cold forms and fully enters the pitch of the screw to provide sealing.

These washers allow for preliminary mounting of the screw (or bolt) before securing with a nut. They are ideal when pre-assembly of the screw and washer is required. They also help reduce assembly time and cost.

The range includes material options that provide corrosion, abrasion and chemical resistance.

  • Materials: Polycarbonate (PC), Polyamide 6.6 (PA) and High Density Polyethylene (HDPE)
  • Colour: Natural

Snap Latch Rivets

Snap Latch Rivets comprise of a Plunger made from Nylon 6 and a Grommet made from Polycarbonate (PC). Together they form a Snap Latch assembly for the joining and securing of panels.

To install; simply push the grommet into the removable panel and then the desired plunger into the grommet. When the panel and plunger are pushed into the fixed panel, it locks them together. Pull on the plunger to easily remove the non-fixed panel.

These handy panel fasteners are ideal for applications that require regular maintenance work. They are offered in easy-grip or mini-grip designs to suit an array of panel hole and thickness ranges.

Snap Latch Rivets are ideal for applications, such as; electrical equipment, metal enclosures, telecommunications equipment, appliances, and more.
