but Yellow Zinc provide a higher corrosion resistance than regular zinc

The screw has a length of 7/8" and a thread of 5/8-11

It is made of plain alloy steel and thus provides low resistance to corrosion in dry and wet environments

these set screws have a thin edge that digs into hard surfaces for a securehold

Socket Head Cap Screw Black Steel 1-1/4-7 * 9" Grade 8 [Cup Point] [Allen Drive] thread_size_18 but Yellow Zinc provide aWith a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head. The screws have a thread of 1 1 4 7 and a length of 9. Black oxide steel screws are mildly corrosion resistant in dry environments. Coarse threads are the industry standard: choose these screws if you dont know the pitch or threads per inch. Screws that meet ASTM A574, ASTM A574M, and ISO 898 1 comply with
