- Screw Size: 5/16-18 x 1 inch Thread Length: 1 inch; Thread Size: 5/16-18
- Head Height: 17.27mm (max); Head Height: 8.12mm (max)
- Please note that, the head height includes the flange while the length is measured from under the head.
- The serrations under the head help grip the surface for mild vibration resistance. The flange help distribute the pressure where the screw meet the surface, eliminating the need for a separate washer.
- Material: High Quality 18-8 Stainless Steel 304, great strength and good corrosion resistance to make fasteners last! Special black treatment makes it better corrosion resistance performance than 304 stainless steel 18/8 material without coating outside. Great choice for both indoor or outdoor projects.
