Makers and machinists, these acetal copolymer rods are seriously versatile material for all kinds of projects! This 2-pack gives you 1-inch diameter rods at 12 inches long, made from opaque black acetal copolymer that meets ASTM D6778 specifications. What's really great about this material is its minimal moisture absorption - meaning it stays dimensionally stable in different environments. It's got high strength and rigidity, excellent abrasion resistance, and is highly machinable with the right tools (use blades with high teeth count for best results). Unlike some materials, these rods have zero centerline porosity issues, preventing outgassing and water penetration. They're perfect for non-marring fixtures, electrical insulators, bushings, bearings, gears, and all kinds of custom parts. Hobbyists love them for knife handles, fishing rod components, and even as substitutes for wood or bone in musical instruments like dulcimers. The chemical and solvent resistance makes them suitable for both industrial and commercial applications. If you're tired of materials that warp, absorb moisture, or don't hold up well, acetal copolymer delivers that perfect balance of machinability and durability. Whether you're running CNC machines, working with lathes, or doing hand fabrication, having some quality acetal rods on hand opens up so many project possibilities. Seriously, every serious workshop should keep some of this versatile material in stock!
