SS304 and 316 are two common grades of stainless steel used in the manufacturing of machine screws.

SS304 refers to stainless steel grade 304, which is an austenitic stainless steel with a composition of 18% chromium and 8% nickel. It is known for its excellent corrosion resistance, high strength, and good formability. SS304 machine screws are often used in applications where corrosion resistance is required, such as in the food and beverage industry, chemical processing, and marine environments.

SS316, on the other hand, refers to stainless steel grade 316, which is also an austenitic stainless steel but with a higher composition of chromium (16-18%), nickel (10-14%), and molybdenum (2-3%). This grade offers even better corrosion resistance than SS304, particularly in chloride environments. SS316 machine screws are commonly used in applications where exposure to saltwater or other corrosive substances is expected, such as in coastal areas, offshore structures, and medical equipment.

Phillip Pan Head refers to the specific head shape of the machine screws. The pan head has a rounded, slightly domed top with a flat underside. It provides a low-profile appearance and offers a larger surface area for distributing the load, making it suitable for applications where a flush or countersunk appearance is not required. The Phillips drive, also known as a cross-recessed drive, features a cross-shaped recess in the head that allows for easy installation and removal using a Phillips screwdriver.

Overall, SS304 and 316 Phillip Pan Head Machine Screws are Stainless Steel Screws with excellent corrosion resistance, high strength, and a rounded, low-profile head shape for various applications requiring durability and aesthetic appeal.
