How can we improve?

2,842 Products

Raw Materials

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Kevlar

Super tough for protection against prolonged wear and abrasion

Aramid

Strong, lightweight, and an excellent thermal insulator; also known as Nomex

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Fastening and Joining

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications
