Heavy Duty Clamps
Heavy duty clamps manufactured according to DIN 3017 standard provide a unique fixing and uniform sealing pressure for high vibration and large diameter applications of agriculture, automotive and other industrial sectors.
Our portfolio covers two heavy duty hose clamp types:
• Super T-Bolt Clamps – fixed bridge, grade 8.8 bolt; ideal for thick-wall hoses.
• Supra Heavy-Duty Clamps – swivelling bridge for fast assembly where hose removal is impossible.
Both designs share a 360° band seat with rolled edges that protect the hose, while the captive nut & spacer deliver uniform sealing pressure.
Options include W1 zinc-plated carbon steel, W2 AISI 430, W4 AISI 304 and W5 AISI 316 stainless – giving you the flexibility to specify the exact heavy duty metal clamps your application demands.

Custom diameters, spring-loaded tensioners and double-band versions are manufactured in-house on request.
Choosing our clamps is not just a purchase — it’s a strategic reduction of total ownership cost.
• Finite-element-tuned designs cut stress hotspots, extending hose life by up to 30 %.
• In-house toolmaking slashes design-change lead-time and keeps IP secure.
• Predictive SPC dashboards ensure < 45 ppm field returns across global OEM programs.
• Eco-efficiency: closed-loop zinc-flake line recycles 92 % of rinse water; 35 % of plant power comes from solar.
