ROADFORMER 2 in Stainless Steel Hose Clamps 40–64mm (10-Pack) — 300-Series, Slotted Hex

ROADFORMER 2-inch hose clamps are full 300-series stainless steel worm-gear clamps sized for 40–64mm hoses, sold as a 10-piece pack for corrosion-resistant, adjustable hose and pipe connections.

These ROADFORMER clamps combine an all-stainless-steel build with a slotted hex head and inner worm gear to deliver reliable clamping for automotive, marine, agricultural and general-purpose use. Each clamp is made from 300-series stainless steel for the band, housing and screw, giving long service life and strong resistance to rust and water exposure. The 40–64mm range (approximately 1.57"–2.5") covers common small- to medium-diameter hoses and tubes, and the pack of ten makes them convenient for projects or maintenance kits.

How do these clamps fit different hose sizes?

The ROADFORMER clamps have a flexible working range from 40mm to 64mm, adjusted by the worm gear screw that moves the band smoothly to the desired diameter. That range suits many coolant, fuel, vacuum and drainage hoses, as well as small ducting and cable bundles. Select a clamp whose maximum/minimum range covers your hose outer diameter for a secure seal.

• Working range: 40mm–64mm (about 1.57"–2.5")
• Inner worm gear for fine adjustment and even pressure
• Use on hoses, pipes, tubes, lines and bundled cables

What materials and build features ensure durability?

Every visible component—the band, housing and screw—is made from 300-series stainless steel, providing strong corrosion resistance in wet or salty environments. The slotted hex head accepts both screwdriver and socket tools for reliable tightening. Together these features reduce the risk of rust, galling and premature failure in outdoor and marine settings.

• Full 300-series stainless steel construction for band, housing and screw
• 5/16" slotted hex head screw for versatile tool use
• Designed to resist corrosion, waterproofing and long lifecycle

How tight can you install them and what torque should be used?

The clamps offer controlled tightening thanks to the inner worm gear; installation torque is recommended between 35–45 in·lbs (4.0–5.1 Nm) for consistent performance. The clamps can withstand an ultimate torque of at least 60 in·lbs (6.8 Nm), giving a safety margin for demanding applications without over-stressing the hardware.

• Recommended installation torque: 35–45 in·lbs (4.0–5.1 Nm)
• Minimum ultimate torque: 60 in·lbs (6.8 Nm)
• Even band pressure reduces risk of hose pinch or leaks

Where are these clamps best used and what comes in the package?

ROADFORMER clamps are suitable for automotive repairs, farm equipment, construction gear, boat plumbing and general household maintenance. The pack contains ten identical clamps so you can replace multiple fittings or keep spares on hand. They are sized for small to medium hose work and perform well in both indoor and outdoor environments.

• Applications: automotive, agricultural, marine, construction, home use
• Pack count: 10 pieces per box for projects and spare parts
• Private-label ROADFORMER packaging with quality control standards

Who is this for: These stainless-steel clamps are intended for mechanics, boat owners, farmers, tradespeople and DIYers who need dependable, corrosion-resistant hose connections in moderate-size diameters. If you require adjustable, reusable clamps that resist rust and deliver predictable tightening torque, this 10-pack covers routine repairs and installation work.
