We’re clearing our remaining W1 Zinc-Plated Steel Kale HD T-Bolt clamps as we transition to full stainless-steel stock. Limited sizes remain — first in, best dressed!
Product Overview
Kale HD T-Bolt Clamps are precision-engineered, heavy-duty hose clamps designed for high-pressure and reinforced hose applications. Manufactured in Europe to DIN 3017-3 standards, these clamps deliver superior strength, reliability, and durability in demanding service conditions across agriculture, automotive, marine, mining, and industrial sectors.
Each clamp features TOX®-Clinching joint technology — a cold-forming press technique that produces joints over 70% stronger than welding and superior to tab-style mechanical locks. With rolled band edges and corrosion-resistant components, Kale HD clamps offer secure, even tightening while protecting the hose wall from damage.
Key Features & Benefits
- TOX®-Clinched joints – 70% stronger than welded or tab-locked joints
- No welds or contact corrosion points – improved durability
- Hollow “D” trunnions – reduce tensile stress on bolt and joint
- Profiled bridge with extended tabs – secure, stable band attachment
- Class 8.8 W1 steel bolts with integrated spacer – no separate bush required
- Rolled band edges – protect hose reinforcement from cutting
- High clamping force, low free torque – efficient and consistent tightening
- Made in Europe – manufactured to DIN 3017-3 standards
