Screws and Bolts

Plastic Socket Head Screws

Plastic screws are chemical and oil resistant, nonconductive, and lightweight.

Nylon-Tip Alloy Steel Socket Head Screws

Nonconductive and softer than brass, the nylon tip reduces vibration and eliminates damage from metal touching metal.

Metric Nylon Pan Head Phillips Screws

Made from nylon, these metric pan head screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Nylon Pan Head Phillips Screws

Nylon pan head screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

High-Strength High-Temperature
PEEK Pan Head Phillips Screws

Reliable in harsh environments up to 500° F, PEEK screws withstand acids, bases, and salt solutions. They are chemical and oil resistant, nonconductive, and lightweight.

Metric High-Strength High-Temperature
PEEK Pan Head Phillips Screws

These metric PEEK screws are reliable in harsh environments up to 500° F and withstand acids, bases, and salt solutions. All are chemical and oil resistant, nonconductive, and lightweight.

Impact-Resistant Polycarbonate
Pan Head Phillips Screws

Polycarbonate screws resist breaking in high-impact applications. All are chemical and oil resistant, nonconductive, and lightweight.

Metric Impact-Resistant Polycarbonate
Pan Head Phillips Screws

Made from polycarbonate, these metric pan head screws resist breaking in high-impact applications. They are chemical and oil resistant, nonconductive, and lightweight.

Plastic Narrow Cheese Head Slotted Screws

Made from nylon, these screws are chemical and oil resistant, nonconductive, and lightweight.

Extreme-Temperature Chemical-Resistant
PTFE Pan Head Slotted Screws

PTFE screws withstand harsh chemicals and temperatures from -100° F to 500° F. They are nonconductive, lightweight, and resist wear due to their slippery surface.

Metric Extreme-Temperature Chemical-Resistant
PTFE Pan Head Slotted Screws

These metric PTFE screws withstand harsh chemicals and temperatures from -100° F to 500° F. They are nonconductive, lightweight, and resist wear due to their slippery surface.

Metric Nylon Pan Head Slotted Screws

Made from nylon, these metric screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Nylon Pan Head Slotted Screws

Nylon screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Impact-Resistant Polycarbonate
Slotted Flat Head Screws

Polycarbonate screws resist breaking in high impact applications better than other plastic screws. All are chemical and oil resistant, nonconductive, and lightweight.

Metric Impact-Resistant Polycarbonate
Slotted Flat Head Screws

These metric polycarbonate screws resist breaking in high-impact applications better than other plastic screws. All are chemical and oil resistant, nonconductive, and lightweight.

Extreme-Temperature Chemical-Resistant
PTFE Slotted Flat Head Screws

PTFE screws are more chemical resistant than other plastic screws and withstand temperatures from -100° F to 500° F.

Fastener Maintenance Assortments

Fastener Caps

Hex Nut Caps

Sized to fit hex nuts, these caps snap on for a tight hold and provide protection from corrosion.

Hinged Fastener Caps

A one-piece hinged design allows frequent access to screw heads without misplacing the top. To conceal and protect the entire screw head, insert your screw through the hole in the base and flip the hinged top over.

Snap-On Fastener Caps

To conceal and protect the entire screw head, insert your screw through the hole in the base and snap on the top.
