Frequently Asked Questions
What is the difference between partial thread and full thread?
Partial thread (also called shoulder bolt or tap bolt) has an unthreaded shank for shear strength. Full thread (fully threaded cap screw) provides more clamping engagement. Standard cap screws above 6 inches long are typically partial thread.
How long will the galvanized coating last outdoors?
Hot Dipped Galvanized fasteners have a thick zinc coating that provides excellent outdoor corrosion protection — typically 20-50+ years in moderate environments. For coastal/marine use, consider stainless steel for longer life.
