Steelsoft Worm Gear Hose Clamps 3/4–1-1/4" (20–32mm) 25-Pack - 304 Stainless, Non-Perforated Roll-Edge

Steelsoft Non-Slip Stainless Steel Worm Gear Hose Clamps (3/4–1-1/4") are a 25-piece set of heavy-duty, rolled-edge, non-perforated clamps engineered to seal hoses without cutting or stripping.

These German-style worm drive hose clamps combine a welded housing, all-304 stainless-steel construction, and a roll-up band edge to protect soft rubber and silicone hoses while delivering reliable clamping torque. Each clamp accepts a 5/16" hex driver for fast installation and meets SAE J1508 standards, making them suitable for plumbing, automotive, irrigation, HVAC and general workshop use.

How do these clamps avoid damaging soft hoses?

The band has a rolled edge and a non-perforated profile so the hose cannot extrude into slots or get cut under pressure. That design spreads clamping force over a broader surface, reducing bite while maintaining a tight seal.

• Rolled-up band edge prevents abrasion and cuts.
• Non-perforated band stops hose extrusion through notches.
• 12 mm (1/2") band width distributes pressure evenly.
• All 304 stainless steel resists corrosion for long service life.

What makes the Steelsoft clamps strong and reliable?

A welded worm housing increases breaking torque and prevents deformation under higher loads; failure torque is rated at 65 lb-in while recommended installation torque is 40–45 lb-in. The screw head is a 5/16" hex for solid engagement with a nut driver or socket to avoid stripping.

• Welded buckle increases strength by approximately 60%.
• Non-stripping screw design for dependable tightening.
• Failure torque 65 lb-in, installation torque 40–45 lb-in.
• Stamped diameter markings for fast size verification.

Are these clamps durable outdoors and in corrosive environments?

Yes — the band, screw and housing are made from 304 stainless steel, delivering strong corrosion resistance. They also pass a neutral salt spray test of 100 hours, suitable for many outdoor and wet applications.

• All-304 SS construction for rust resistance.
• 100-hour neutral salt spray test performance.
• Zinc-plated screw recommended to reduce micro-welding in high-speed applications.
• Good fit for pools, irrigation, and marine-adjacent installations.
