Self-Drilling Screws
Self-Drilling Screws
Realm Intermediates offers Self-Drilling Screws. These are specifically developed for various applications. They provide high pullout strength; shear strength and maximum thread engagement and positive fastening in both structural steel and timber constructions. With these fasteners, fastening jobs are simplified into one. These mean that buildings can be erected faster at lower costs. Assembly and on-site labour time is greatly reduced by eliminating the task of alignment or the need to pre-drill holes. Fastening operations in roofing, cladding and assembly can be completed in less time often halving the time of the old conventional method. These are easy to use even by unskilled labour as selection of drill size and various tools are eliminated. As the fastenings are reduced to one operation, alignment problems are eliminated. These are more economical to use self-drilling screws than to drill, tap and fasten or nut and bolt in the traditional manner. Best results are obtained with electric screwdrivers of approximately 380 to 650 W operating, between 2,000-2,500 rpm.
