Hexagon Head High Tensile Set Screws DIN 933 Grade 8.8 & 10.9
Grade 8.8 & 10.9 High tensile hexagon head set screws DIN 933 are sometimes referred to as fully threaded bolts or set pins. They are easily identified by their 8.8 & 10.9 head markings and usually but not always have metric thread forms. The most common surface finish in use is Cr3 bright zinc plated. Hot dipped galvanised finishes are becoming ever more popular, particularly in the rail industry sector. Self-colour or unplated types are now seldom used, but are normally available next day to order. Set screws are most often used in conjunction with Form A DIN125 washers and DIN 934 Full nuts. Typical applications for this very widely used product include steel fabricators, machine builders, automotive applications and the construction industry.
