Keep wires in place while preventing connections from short circuiting. Since these screws are made of nonconductive plastic, electricity can't pass through them as the wide, tapered head secures wires. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.
Length is measured from under the head.
Nylon—The most common plastic rounded head screws, these are good for general purpose fastening. Slippery and abrasion resistant, they thread in smoothly and stand up to daily wear and tear. Nylon will swell and weaken when exposed to moisture, so these screws are best for dry environments.
