Metric Class 12.9 Socket Head Cap Screw and 12.9 Grade Hex Screw manufacturers in India

12.9 Screw is a broad category of mechanical fastener with a threaded shaft, designed to screw into a part. It includes self-topping screws and wood screws, which have a tapered shaft with sharp threads designed to cut a mating thread in the part to which they are fastened. It also includes machine screws, which much more closely resemble bolts, but their whole shaft is normally threaded. Grade 12.9 Screws often depends on friction at the threads to remain securely fastened. And in the situation of a self-tapping screw, radial expansion of the hole causes much of this friction. 12.9 Socket Head Cap Screw resists more torque for a tighter hold.  It has a head height that matches the screws thread diameter. It is typically used in machine parts, die fixturing, and clamping. Grade 12.9 socket head cap screws is with a full thread is another tall-headed, internally-driven high-strength fastener. It is perfect for the applications in which there is not enough space to maneuver wrenches or sockets. 12.9 hex head cap screw is a six-sided bolt with a trimmed hex head and a washer face on the bearing surface. It is easy to install with a wrench for a secure hold. It is used with a nut or in tapped holes.
