Machine Screws

Unlike self-tapping screws, which are meant to be buried into the substrate – machine screws are used when you need to go all the way through the material – often referred to as through-bolting.  With this type of screw you’ll also need to add some sort of nut (and often a washer) to safely secure the machine screw in place.  Fisheries Supply stocks a wide variety of types – including pan head, oval head, flat head and even metric machine screws to help you get the job done – so shop today and save!
