Probably there is no name. better known in connection with small screws and like articles than Nettlefolds. To the range of products offered by Guest, Keen and Nettlefolds, Ltd., Heath Street, Birmingham, have recently been added Nettlefolds and Parker-Kalon hardened self-tapping screws. These are available in a wide variety of types.
They are made with countersunk, round, cheese and hexagon heads, and the time they save in eliminating the need for tapping is considerable. Moreover, the screws remain secure without the use of locking washers or other devices for the same purpose. This and the facility with which the screws can be inserted are due to the unique thread structure, and the special hardening treatment employed.
