Plastic Socket Head Screws

Fully Threaded

Secure parts without adding much weight. These plastic screws are also nonconductive and resist chemicals and oil. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.

Length is measured from under the head.

High-Strength High-Temperature PEEK—Our strongest plastic screws. They withstand high heat, but don't resist impact well, so they might crack or dent from hard bumps and vibrations.

Plastic Hex Head Screws

Fully Threaded

Secure parts without adding much weight. These plastic screws are also nonconductive and resist chemicals and oil. The head's six flat sides keep wrenches and sockets from slipping and rounding off the drive.

Length is measured from under the head.

High-Strength High-Temperature PEEK—Our strongest plastic hex head screws. They withstand high heat but don't resist impact well, so they might crack or dent from hard bumps and vibrations.

Glass Filled—A blend with 30% glass, these screws are nearly twice as strong as standard PEEK 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.

High-Temperature High-Strength PEEK—Our strongest plastic screws. They also won't degrade from high heat, so they're good for joining components on circuit boards and other electrical applications. They aren't very impact resistant, however, and may crack or dent if subjected to hard bumps and vibrations.

Metric Ultra-Precision Lead Screws and Nuts


	Style B	Style C

Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.

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.

High-Strength High-Temperature PEEK—These offer the best strength of all our plastic screws. They also won't degrade when exposed to high heat, so they are a good choice for joining components on circuit boards and other electrical applications. They aren't very impact resistant, however, and may crack or dent if subjected to hard bumps and vibrations.

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

Precision Acme Lead Screws and Nuts

Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.

Round Nuts—Right-Hand Thread

PEEK—PEEK plastic nuts handle twice as much heat as PET and acetal plastic nuts. They have good chemical resistance and excellent corrosion resistance.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
