Gr4.8 Gr8.8 Gr10.9 JIS B1176 Hex Socket Knurled Cap Screw Hex Head Bolt
Gr4.8 Gr8.8 Gr10.9 JIS B1176 Hex Socket Knurled Cap Screw Hex Head Bolt
Description:
Socket caps have a small cylindrical head with tall vertical sides. Allen (hex socket) drive is a six-sided recess for use with an allen wrench (hex key).
The most common stainless steel for general hardware use is stainelss steel 304, which is also called stainless steel 18-8.Stainless steel 316 is A highly corrosion resistant grade of stainless steel. Ideal in salt water and chlorine environments. More expensive than 18-8. Zin plated alloy steel is another a very high strength heat treated alloy steel. Zinc plated for moderate corrosion resistance. Alloy steel black oxide finish is also a very high strength heat treated alloy steel. Black oil (plain) finish. We always has Gr12.9 Gr10.9 DIN912 Hex socket cap screws in stock. The thread is machine thread.
Also a type of DIN912 is without knurled, which is smooth. It has tempered medium carbon steel. Grade 8 is stronger than grade 5, and is commonly found in high strength automotive applications. Chrome plated and polished for a mirror like finish.
ASME standard socket cap screws are from0to 2” diameter. These socket cap screws are manufactured to the most recent ASME B18.3, IFI, or customer stated standards with either full or partial threaded options. Our stockisthousands of these socket cap screws in any of our various materials and sizes.
