A new, enlarged group of zinc-plated steel and Nylon machine screws and nuts suited for a variety of fastening applications are now available from Keystone Electronics Corp., represented in Australia by NPA Pty Ltd.

The expanded group features four different head types consisting of binding heads to assure firm, electrical connections; flat head styles for use where fasteners cannot protrude above mating surfaces; pan head types to replace round head styles and for cosmetic enhancement and smooth surface area uses; and self-tapping, washer/hex head styles for sheet metal applications where machine thread inserts are not furnished.

All feature slotted heads in a choice of 2-56, 4-40, 6-32, 8-32 and 10-32 threads with lengths from 1/4" to 1 1/2". Mating hex nuts are also supplied in zinc-plated steel as well as Nylon.

These latest availabilities are designed to complement a wide range of diverse hardware supplied in bulk through Keystone's global distribution network.
