Hex Washer Flange Tek Screws

Hex washer flange self-drilling screws. The flange under the hex is formed as part of the head, so there is no washer to lose on site and the serrated underside resists backing out under vibration.

  • IFI, DIN, JIS, GB or drawing

Questions we get asked about this item

Flange head or hex washer head — what is the difference in practice?

Both spread load. The flange version carries a larger, usually serrated bearing face moulded into the head, which is what you want on a joint that sees vibration.

Can the flange be supplied with a bonded washer as well?

Yes, where the fixing has to seal as well as clamp. Specify the washer outside diameter — 14mm, 16mm or 19mm — with the order.
