Allen screw socket head cap or Allen head bolts are commonly used in machine assembly, especially for removable panels and parts, they have a round cap with a hex head and are tightened with a socket wrench drive, choose the right cap head for your specific application, longer caps are easier to see when fastened, while button and flat head caps are less apt to snag clothing or linkages, chrome cap bolt has a great appearance, those with a black oxide or armor coat finish resist corrosion
Also, our custom fastener, bolts, and screws are widely used in the below industries
- Consumer products
- Heavy machinery
- Oil and gas
Types of Allen Screw and Allen Bolt
Cup Head has a flat, chamfered top surface, a smooth or knurled or straight pattern of cylindrical sides, and a flat bearing surface. Compared with the usual cup head, the small cup head hex head screw with smaller head thickness is mainly used for small height occasions. Socket caps have a small cylindrical head with tall vertical sides. Allen (hex socket) drive is a six-sided recess )Internal Hex Socket) for use with an Allen wrench (hex key). This design is the workhorse of the machine-building industry.
The most important reasons for the increasing use of socket head cap screws in the industry are safety, reliability, and economy
countersunk head Allen screws have a flat top surface and a conical bearing surface with a countersunk head angle of about 82°/90°/120°. This type of metric Allen head screws can be screwed in completely and will not protrude on the surface of the assembled product, Allen CSK Flat head screws are used for flush mounting of sections, usually where one part slides over another or one part is mounted on another. Flathead screws, like button heads and low heads, are limited by configuration in their tensile strength capability. Because of this, they should not be used in applications requiring full strength, where Socket Head Cap Screws should be used.
The button head Allen screws or pan head hexagon socket screws have a low arc top surface and a large flat bearing surface. The hexagon socket step screw is a screw having a cylindrical step under the head. The ultra-low head metric hex socket screw has a circular arc from the side of the head and can withstand a large force area. The Socket Button Head Screw design is primarily used where a lower profile head is required and for aesthetical reasons. These screws can take a lower tightening torque as compared to the DIN 912 screws
Allen Grub Screw: A set screw is a threaded fastener that normally does not have a head. Unlike most other threaded fasteners it is basically a compression device normally used to generate axial thrust. It is also known as a grub screw. It is used to hold parts like a sleeve, collar, coupling, gear, etc. on a shaft to prevent relative motion.Socket set screws offer three types of holding power: torsional (resistance to rotation); axial (resistance to lateral movement); and vibrational. Size selection is an important factor in holding power. the point selection base on the application set screw has a plain cup, knurled cup,flat, cone, dog
