ROADFORMER 3" Stainless Steel Hose Clamps 65–89mm (10 Pack) — Full 300-Series, Hex-Head Worm Gear

ROADFORMER 3" hose clamps are fully stainless-steel worm-gear clamps sized for 65–89mm (2.56"–3.50") applications and sold in a box of ten for reliable, corrosion-resistant hose fastening.

These ROADFORMER clamps combine full 300-series stainless-steel construction with a slotted hex-head worm screw for smooth, adjustable tightening. They fit a wide range of hoses, tubes, and small-diameter pipes used across automotive, marine, agricultural, and household projects. Built for long service life and resistance to rust, each clamp delivers consistent clamping force with a torque profile suitable for repeated installations and outdoor exposure.

How do these clamps adapt to different hose sizes?

The clamps feature an inner worm gear mechanism that moves the band evenly as you turn the screw, enabling precise diameter adjustment across the 65–89mm range. That flexibility makes them useful for slightly undersized or oversized fittings within that span.

• Working range: 65mm to 89mm (2.56"–3.50").
• Inner worm-gear design for smooth, predictable adjustment.
• Slotted 5/16" hex-head screw for common hand or socket drivers.
• Adjusts to mild variations in hose outer diameter without damaging the hose.

How durable and corrosion-resistant are these ROADFORMER clamps?

Every component — band, housing, and screw — is made from 300-series stainless steel to resist corrosion, staining, and rust even in damp or marine environments. The full-stainless construction reduces galling and extends service life compared with single-plated alternatives.

• 300-series stainless steel for band, housing, and screw.
• Designed for outdoor, marine, and moist environments.
• Long life-cycle performance versus plated clamps.
• Maintains clamping integrity under repeated use.

What tightening performance and tools work best?

The clamp delivers a reliable torque range that balances secure sealing with protection against over-compression. Use a 5/16" (or equivalent) compatible driver for best control; a torque wrench can help hit recommended values when needed.

• Installation torque recommended: 35–45 in·lbs (4.0–5.1 Nm).
• Ultimate torque capacity: at least 60 in·lbs (6.8 Nm) minimum.
• Compatible with standard slotted or hex drivers and sockets.
• Inner-gear ensures even force distribution to reduce hose damage.

Where are these clamps best used and how many come in a pack?

These clamps are versatile across many industries and household uses. ROADFORMER supplies them in a ten-piece set so you have spares and enough clamps for multiple repairs or installations.

• Common applications: automotive cooling and vacuum lines, garden and irrigation hoses, small marine hose connections, agricultural tubing, and general plumbing or workshop use.
• Marine-suitable due to stainless construction; check compatibility with fittings and codes.
• Pack quantity: 10 clamps per box for projects and replacements.
• Private-label ROADFORMER packaging signals consistent quality control.

Who is this for: DIYers, mechanics, marine hobbyists, farmers, and maintenance professionals who need reliable, corrosion-resistant clamps for 65–89mm hoses and small pipes. If you want hardware that resists rust, installs with common drivers, and comes in a quantity suited to repeat jobs or fleet maintenance, this 10-pack of ROADFORMER 3" stainless-steel hose clamps is a practical choice.
