10-pack worm gear hose clamps
These Zoro Select 43287 worm gear clamps come in a pack of ten and are designed for securing hoses with inside diameters between 4 1/8 inches and 5 inches. The 1/2 inch wide perforated band is made from 304 stainless steel and uses a zinc-plated steel screw with a 5/16 inch hex drive.
Check hose diameter and drive tool
Verify that the hose or pipe you plan to clamp falls within the 4 1/8 inch minimum and 5 inch maximum inside diameter range. You will need a 5/16 inch hex driver or compatible slotted tool to tighten the slotted hex screw during installation.
Stainless band with zinc-plated screw
The 304 stainless steel band resists corrosion in damp or outdoor environments while the zinc-plated steel screw provides reliable clamping force. The perforated band design allows the worm gear threads to engage securely along the full circumference for a uniform seal.

Questions about this item
What is included in the pack and do I need to buy a driver tool separately?
The pack contains ten stainless-steel worm-gear clamps with 1/2 in band width and a 4 1/8 in to 5 in clamping range; a 5/16 in slotted-hex driver or socket is required but not included.
Which SAE size should I choose for a hose with an outside diameter near 4 1/2 in?
SAE 72 covers 4 1/8 in to 5 in inside diameter, so it fits hoses in that range; choose a smaller SAE size only if the hose OD falls below 4 1/8 in.
What does the 0.02 in band thickness mean when the clamp is tightened on a radiator hose?
The 0.02 in thick Grade 304 stainless band distributes clamping force evenly without cutting into soft rubber, while the zinc-plated steel screw provides the tightening torque.
