ON CLEARANCE – UNTIL ALL STOCK SOLD.

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
