HT150 BI-HEX 19BW

11mm standard BI-HEX nylon moulded head fasteners. All our fasteners are  Moulded in the UK.

Topfix is not generally recommended. If unavoidable or specified for a particular application a saddle/storm washer should be used and particular care taken in installation.

A 6.3mm diameter coarse thread just under the head stitches the top outer sheet of the composite panel to the head keeping the sheet and washer clamped together giving a typical ultimate resistance force of 1.4kN in normal applications.

See fastener specifications link below.

A minimum 45mm embedment is recommended for HT into timber.

See moulded head specification link below.

See Composite panel selection chart below.

These fasteners have a minimum 500hr SST coating. Link below.

The length specified is the length of the fastener from under the head before moulding, Add approximately 8mm to the length of the fastener for the total length including the moulded head.

Colours please see our colour availability page for a *full list of colours. Do not rely on colour matching from the colours on the images as they will vary due to reproduction and screen resolution.
