Electrical Grounding Screws
 |
Green so you know they’re for grounding, these screws secure electrical connections. The wide flange creates a solid, flat contact surface for reliable conductivity. As you drive these screws, they cut their own threads in drilled holes.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Grounding Hex Head Screws
 |
Green so you know they're for grounding, these screws secure electrical connections. The flange creates a solid, flat contact surface for reliable conductivity. If there isn't enough room to turn them with a wrench, slip a screwdriver into their slotted drive. When using a wrench or socket, the head's six flat sides prevent slipping and rounding off the drive.
Head height includes the flange. Length is measured from under the flange.
Low-Strength Fastener—Suitable for light duty applications, such as securing access panels. These screws have a tensile strength of 60,000 psi and lower.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
