SPECIFICATIONS
Has a similar thread design as a socket cap screw. The dome-shaped head is wider and has a lower profile than a socket cap screw. Used when a wider bearing surface or a smoother, more finished appearance is desired. Button head cap screws do not afford the strength of socket head cap screws and are designed for light fastening applications. They are not recommended for critical, high strength applications. Mechanical Zinc plating, which is the process by which the fasteners are tumbled in a drum with glass beads, water, chemicals and zinc powder. The collision creates a cold welding of the zinc powder onto the parts. Advantages : Elimination of hydrogen embrittlement, excellent adhesion, uniformity of coating thickness. Ability to plate hardened parts without post baking.
