Exhaust Clamps

Exhaust Clamps, also known as U Bolt Clamps, are primarily used for automotive purposes to fix the exhaust to the vehicle, avoiding the need for welding.

A good quality clamp will improve the performance of a vehicle, as a faulty clamp means that the air flow is not restricted though the exhaust. This will lead to loss of power from the engine and a sub-standard performance from your car or van.

As well as being used to improve the performance of vehicles, Exhaust Clamps also have other non-automotive uses, such as holding pipes or tubes in place on both the interior or exterior of a property.

Exhaust Clamps are manufactured in mild Steel Zinc Plate and are supplied complete with nuts.

Available from Fastenright in sizes M6, M8 and heavy duty M10, as well as 3/8″ BSW. Bore size ranges from 28mm to 153mm.
