ROADFORMER 1.75" Stainless Steel Hose Clamps 33–57mm (10 Pack) — Full 300-Series, Worm-Drive

ROADFORMER 1.75" hose clamps are full 300-series stainless steel worm-drive clamps sized for 33–57mm (1.3"–2.25") hose outer diameters, supplied as a 10-piece set for durable, corrosion-resistant fastening.

These clamps combine all-stainless construction with a slotted hex-head screw and inner worm gear to give reliable tension control across a flexible range. Built from 300-series stainless steel for band, case and screw, they resist rust and stand up to repeated use in wet, salty or dirty environments — useful wherever hoses, pipes or cables need secure mechanical fastening.

How does this clamp perform on corrosive or wet jobs?

The ROADFORMER clamp uses 300-series stainless steel throughout, which improves resistance to rust and staining compared with plated or mixed-metal clamps. The single-material build reduces galvanic corrosion risk at joints and keeps the clamp turning smoothly over time.

• All 300-series stainless band, housing and 5/16" slotted hex screw
• Designed for marine and outdoor exposure
• Inner worm gear minimizes seizing and galling

What hose sizes and applications does it cover?

Each clamp adjusts from 33mm to 57mm (about 1.3" to 2.25"), matching the common 1.75" nominal size. That span fits many automotive vacuum and coolant lines, garden and irrigation hoses, marine plumbing and general household or light-construction piping.

• Use on hose, pipe, tubing and cable bundles within the diameter range
• Typical applications: automotive, agriculture, construction, marine, home maintenance
• Ten clamps in one box for multi-point projects or spares

How easy are these clamps to install and adjust?

The internal worm gear and slotted hex-head screw let you fine-tune the clamp diameter with a screwdriver or socket. Installation torque and ultimate torque specs guide tightening to avoid over-compression while achieving dependable sealing force.

• Smooth inner worm gear for precise diameter adjustment
• Recommended installation torque: 35–45 in·lbs (4.0–5.1 Nm)
• Ultimate torque capacity: minimum 60 in·lbs (6.8 Nm)

Will these clamps hold up under repeated use or high vibration?

The full stainless construction and the worm-drive design provide durability for repeated removal and reinstallation. For vibrating environments, proper torque and placement increase retention; the robust screw and housing resist thread wear and loosening over time.

• Durable 5/16" slotted hex screw resists rounding
• Reinstallable without rapid thread degradation
• Works well in intermittent high-vibration settings when torqued correctly
