T Bolt Clamps
T Bolt Clamps also known as Bolt Clamps or Heavy Duty Hose Clamps are a type of hose clamp that use a bolt to tighten or loosen the band around a hose or tube. They are commonly used in applications that require high clamping force and durability such as automotive industrial and marine environments. Bolt clamps come in different shapes and sizes depending on the hose or tube they are designed to fit.
These clamps have a T-shaped bolt that runs across the top of the band and is secured by a nut at each end. They are easy to install and adjust and can provide a uniform seal around the hose or tube. T Bolt Clamps are suitable for high pressure and high temperature installations such as turbochargers exhaust systems and coolant hoses where reliable sealing is essential.
Material Quality Comparison
| Material Quality | Band | Housing | Screw |
|---|---|---|---|
| W1 | Mild steel zinc plated | Mild steel zinc plated | Mild steel zinc plated |
| W2 | Stainless steel 430 | Mild steel zinc plated | Mild steel zinc plated |
| W4 | Stainless steel 304 | Stainless steel 304 | Stainless steel 304 |
W1 is made entirely of mild steel and is the most cost effective option but offers the lowest level of corrosion resistance of the hose clamp materials. W2 is also made from mild steel but includes a stainless steel band which provides improved corrosion resistance. W4 is made entirely of stainless steel 304 which is the most corrosion resistant and durable material option. Bolt clamps are also available in different sizes and clamping ranges. These hose bolts are an essential accessory for securing and sealing hoses and tubes helping to prevent leaks while maintaining performance under demanding conditions.

We also offer Worm Drive Hose Clamps and Petrol Pipe Clamps.
Applications of T Bolt Clamps in the UK
In Britain T Bolt Clamps fulfil critical applications across many industrial sectors by ensuring sturdy reliable fastening of heavy high pressure hoses tubing and coolant lines. Common examples include:
- Manufacturing equipment – T Bolt Clamps can withstand hydraulic fluid pressures and vibration from pumps cylinders and presses helping to avoid leaks on braided or rubber hydraulic hoses
- Chemical processing plants – Fully stainless steel options such as W4 and W5 resist corrosion from acids alkalis solvents and frequent washdowns
- Construction machinery – Heavy equipment often relies on secure hydraulic lines and air brake hoses where high strength clamps reduce the risk of disconnection caused by vibration
- Transportation industry – Heavy duty hose clamps are often used on lorries and buses for securing air brake lines turbo coolant lines and charge air tubes that must withstand fluctuating pressures
- Gas utilities – Stainless steel T Bolt Clamps may be used in fuel gas piping and appliance systems subject to required certifications while fully stainless components also resist outdoor weathering

Explore our extensive selection of T Bolt Clamps stocked as standard in material options including W1 W2 and W4 and in hole diameter sizes from 17mm up to 252mm. We can also offer sizes to suit inch diameter requirements when needed and W3 and W5 material standards are available upon request. W4 T Bolt Clamps typically include 302 and 304 stainless steel components while W5 offers a fully 316 stainless steel solution for the highest corrosion resistance.
Bespoke sizing available for heavy duty T Bolt Clamps
Our broad range of sizes suits many common applications but if you need a clamp size or specification not shown on our website our team can help with custom options. Contact us with your hose diameter band width requirements and operating conditions to ensure the most suitable clamp selection.
Benefits of stainless steel T Bolt Clamps
For heavy duty industrial and outdoor applications we recommend W4 and W5 T Bolt Clamps which are constructed from stainless steel grades 304 and 316. These materials provide superior durability and corrosion resistance helping prevent seizing and offering strong protection against rust chemical exposure and weathering. W5 stainless T Bolt Clamps offer the best performance in aggressive environments including saltwater conditions common in marine settings.
Reusable and adjustable fastening
The adjustable band design of T Bolt Clamps enables a secure grip across a range of hose sizes while maintaining even pressure around the circumference. Their reusable construction makes them a cost effective choice for maintenance work and line changes compared with single use alternatives.
Consider using spiral wrap with T Bolt Clamps
For added protection it can be useful to reinforce the hose surface where clamping takes place. Our spiral hose wrap is made from high density polyethylene and is designed to envelop hoses to protect against abrasion impact elevated temperatures and chemical exposure. In commercial and industrial environments extending hose lifespan can deliver long term cost savings while improving reliability.
