Plastic Slotted Flat Head Screws

These plastic screws are lightweight, nonconductive, and naturally resistant to rust. Use them to attach panels and covers to electronics and automated equipment. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.

Length is measured from the top of the head.

Clear Impact-Resistant Polycarbonate—Our most impact-resistant plastic flat head screws, these withstand bumps and vibration without cracking or breaking.

Standard Profile—Standard-profile heads are the most common choice for flat head screws.

Plastic Pan Head Phillips Screws

Our most common plastic pan head screws, these are often used to attach panels and covers to electronics and automated equipment. They're lightweight and nonconductive. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.

Length is measured from under the head.

Clear Impact-Resistant Polycarbonate—Our most impact-resistant plastic rounded head screws. These absorb bumps and vibration without cracking or breaking.

Through-Panel-Mount Binding Posts

Before making a permanent connection, use these connectors to test a circuit. Also known as binding posts, they mount through panels to create a connection point.

All connectors are insulated to prevent contact with panels.
