Worm-gear hose clamp with a stainless-steel band and housing for corrosion resistance, paired with a zinc-plated carbon-steel screw. Tightens evenly around hoses for a leak-resistant seal on automotive, marine, plumbing, and shop air applications.

• Stainless-steel band and housing resist rust and corrosion
• Zinc-plated, chromate-finished carbon-steel screw
• 9/16" wide band distributes clamping pressure evenly
• 5/16" hex head screw - tighten with a nut driver or flat screwdriver
• Clamping range: 1/2" x 1-1/4"

Tip: Pick a clamp whose range puts your hose diameter near the middle, not the extremes, so the screw has thread engagement in both directions.
