Hex Flange Head Screws - Steel to Steel can be used for general construction and in many air-conditioning, heating, electrical and ventilation applications when fastening sheet metal and hardware. No pre-drilling is necessary as the screws tap their own thread, with the drill point removing excess material. Available in sizes 4.2 x 13mm up to 5.5 x 38mm.
Hex Flange Head Screws are also known as TEK Screws.
