Worm Drive Hose Clamps

Murray is a manufacturer of multiple grades and sizes of traditional Worm Drive hose clamps. Our SAE type F clamps have all stainless steel bands and housings. A Murray tradition for over 90 years.

H Series – “Gold” Screw Clamps
Band and housing are 200/300 series stainless steel. Screw is 5/16” slotted hex head, heat treated carbon steel, double plated with zinc plus trivalent chromate for long lasting protection. Good general-purpose clamp.

HSS Series – With “400” Series Steel Screw Clamps

Band and housing are 200/300 series stainless steel. Screw is 5/16” slotted hex head, heat treated 400 series stainless steel. The high corrosion resistance of this all stainless steel band, housing and screw makes this the perfect clamp for numerous industrial installations.

HFSS Series - All “300” Series Stainless Steel Construction Clamps
Band, housing and screw are 300 series stainless steel. Screw is 5/16” slotted hex head. The all-300 series stainless steel construction provides better corrosion resistance than that available from the “H-SS” Series, making this worm drive clamp well suited for marine applications.

"T-SS" Series - With "400" Series Stainless Steel Screw
Band and housing are 200/300 Series Stainless Steel. Thumbscrew is heat-treated 400 Series Stainless Steel. General-purpose clamp for applications that require only finger tightening.
