الوصف

The Unbrako class 12.9 alloy steel socket cap screw has a black oxide finish, flat head, and hex socket drive, and meets American National Standards Institute ANSI B1.13M specifications. Class 12.9 alloy steel, composed of quenched and tempered alloy steel, is often used in applications where strength is the primary consideration. The material is magnetic. The black oxide finish offers mild corrosion resistance and lubricity. The flat head is cone shaped for use in countersunk holes and has a flat top that fits flush with the mated surface. The hex socket drive, also known as an internal hex drive, has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench.Socket cap screws are threaded fasteners that have a cap head with an internal socket drive for installing in areas with limited side clearance. These screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of tool required to install the screw.Unbrako manufactures high-strength socket screws and other fasteners, including dowel pins and shoulder screws. The company, founded more than 80 years ago, meets International Organization for Standardization (ISO) standards 9001:2000 and TS 16949:2002.
