These A4 stainless steel self-tapping threaded inserts are a useful way to achieve a strong, permanent metric thread in soft materials such as wood or fibre glass. They are ideal for many situations where only single-sided access is available to you. ​Manufactured in stainless steel ensures they will remain corrosion resistant.

Installation can take place when a suitably sized hole is drilled into the wood or fibre-glass. The insert can then be screwed into the hole using its self-tapping thread.  It is recommended to first test the hole size required on an unimportant area or a scrap piece of material. The external thread will self-cut into a pre-prepared hole in a similar way a wood screw does providing a metric thread.

Blind self-tapping inserts can be used in applications where any fluid ingression along the internal thread could be an issue like ponds, water features, swimming pools or water butts.

The head of the insert is shaped to sit fully flush once correctly inserted in order that it blends in with the existing area. Below the head is a recess to provide a space for sealant to squeeze into when a watertight fit is required.
