Metal Self Tapping Retaining Washers

Self-drilling and self-piercing screws are a type of fastener that combines drilling and fastening operations in a single action, removing the requirement for pre-drilling. They have a pointed head that allows the screw to self-tap into a panel. This reduces the amount of time and physical work necessary for fixing.

Easily driven into the surface with a power drill or screwdriver and provides a strong and secure hold. Ideal for use in applications where a high degree of strength and stability is required, such as in metalworking or construction.

Our range of Standoffs, which are commonly referred to as Hex Spacers or Standoff Pillars, are quick and easy to install thanks to their screw-in design. Our standoffs are available in both a non-undercut and undercut version. Non-undercut spacers offer greater stability, but require a washer for installation. Whereas undercut spacers are much quicker to install, and allow spacers to be stacked and do not require the use of a washer - making them a econonical solution. Our spacer range is also available in self-tapping types for mating with non-threaded fittings.

Our standoff spacers offering includes undercut male to female standoff made from either, nickel-plated brass, zinc-plated steel, aluminium or stainless steel, which are self-tapping. Female to female hex spacers made from brass, stainless steel, nickel-plated brass or zinc-plated steel. A self-tapping male to female hexagonal spacer made from nickel-plated hardened steel that's brass coloured. We also offer a round natural Nylon 6/6 push spacer.

This range of Captive Washers has a very shallow thread on the inside diameter. This means they can be screwed on, and once past the threads they will not separate from the captive screw or bolt.

How to install a captive screw and washer assembly;
1) Place the captive screw into the panel hole.
2) Thread the washer on to the screw, beyond the threaded part of the screw, which retains the screw in the panel.

The washers are made from Stainless Steel that provides good resistance to corrosion and machinability. The material is a popular choice for construction and automotive applications.
