Countersunk Head - Heavy Section

Designed to fix timber to steel, the timberfix range first drill a clearance hole through the timber using the winged area of the product.  These wings break off when they come into contact with the steel allowing the drill point to drill the steel to the correct size to give a positive engagement every time.  Heavy section screws have fine threads suitable for use in steels from 4mm - 12.5mm thick.
