The amount of pressure that a worm clamp can hold can vary depending on several factors such as the size and material of the clamp, the condition of the screw and cage, and how tightly the clamp is tightened. However, it is generally accepted that worm clamps can withstand significant pressure.
One important thing to note is that the pressure capacity of a worm clamp is typically measured in inch-pounds (in/lbs). This refers to the amount of force applied at a distance of one inch from the center of the screw. So, when we say that a worm clamp can hold over 135 in/lbs of pressure, it means that the clamp can withstand a force equivalent to 135 pounds applied at a distance of one inch from the screw.
To ensure that the clamp can hold such pressure, it is crucial that the screw is properly tightened. The screw of a worm clamp is designed to be tightened by hand, using a screwdriver or a wrench. When tightening the screw, it is important to apply enough force to secure the clamp in place, but not to overtighten it to the point where the screw slips or the cage becomes deformed.
Personal experience has shown that hand-tightening a worm clamp to over 135 in/lbs of pressure is indeed possible without any issues. I have used worm clamps in various applications, such as securing hoses and pipes, and have found that they can withstand significant pressure when properly tightened.
It is worth mentioning that the pressure capacity of a worm clamp can also depend on the material it is made of. Worm clamps are commonly made of stainless steel, which is known for its strength and durability. However, there are also worm clamps made of other materials such as carbon steel or plastic, which may have different pressure capacities.
A worm clamp can typically hold over 135 in/lbs of pressure when properly tightened. It is important to ensure that the screw is tightened enough to secure the clamp in place, but not so much that it slips or deforms the cage. By following these guidelines, a worm clamp can provide reliable and secure fastening for various applications.
