12 best heavy duty clamps
Heavy-duty clamps are robust and durable tools designed for securing and holding objects firmly in place. They find applications in various fields, including woodworking, metalworking, construction, and automotive work. Here are some key features and uses of heavy-duty clamps:
Construction and Materials: Heavy-duty clamps are typically made of sturdy materials such as steel or cast iron. This construction ensures durability and strength, allowing the clamps to withstand significant pressure and stress.
Types of Heavy-Duty Clamps:
- C-Clamps: These have a C-shaped frame and are used for holding together two objects. They come in various sizes to accommodate different workpieces.
- Bar Clamps: These have a long bar that can be adjusted to the desired length. Bar clamps are useful for clamping large or irregularly shaped objects.
- Pipe Clamps: Designed with a pipe that can be threaded, these clamps are suitable for large and heavy-duty projects.
Adjustability: Heavy-duty clamps are often adjustable to accommodate various sizes of workpieces.This adjustability is essential for ensuring a secure and tight grip on different materials.
Applications:
- Woodworking: Heavy-duty clamps are commonly used in woodworking for tasks such as gluing, clamping boards together, or securing pieces during cutting or shaping.
- Metalworking: In metal fabrication, these clamps are employed to hold metal pieces securely during welding, cutting, or machining.
- Construction: Heavy-duty clamps play a role in construction projects for securing materials in place and ensuring precise alignment.
Throat Depth: The throat depth of a clamp is the distance from the screw to the bar. A larger throat depth allows the clamp to reach further onto the workpiece.
Clamping Force: Heavy-duty clamps are designed to provide substantial clamping force, ensuring that the workpiece stays firmly in position without slipping.
Quick-Release Mechanisms: Some heavy-duty clamps feature quick-release mechanisms for easy and rapid adjustment. This can be particularly useful in applications where frequent adjustments are needed.
When using heavy-duty clamps, it's important to follow safety guidelines and ensure that the clamps are appropriate for the specific task at hand. Choosing the right clamp for the job contributes to efficiency and safety in various work settings.

User questions & answers
Question: | What is the weight of each clamp |
Answer: | I did not use the handle or the screws that came with it, the handle was to short to push heavy snow.I bought 1 1/4" wood closet pole rod that was 57" in length, then sanded down one of end of the pole to taper it so it would fit in the shovels's sleeve, then used stainless steel 1" fillips drywall screws to secure it.This worked perfectly with last years record amount of snow. |
Question: | Will they rust outdoors |
Answer: | mine did also I bought some stainless steel screws and bolted them right through .works great |
Question: | making frames with 45 degree angles will this hold |
Answer: | I do not know if it comes in a wider width; however, you should contact the Vendor to see if they have (or plan to have) a wider width in the future. It could increase their sales. |
Question: | I need to know if the openings are really a 3 inch jaw opening. i have purchased 2 sets from other companies & they really didn't open 3" as advertise |
Answer: | I would think that would be possible, however to be sure, you need to measure (or find out from the seller), the distance in inches between the "V" shape portion which, I believe is designed for about 1,1/2" dia. handles. |

User questions & answers
Question: | Are other buyers getting lesser rated irwin clamps instead of hd clamps they ordered |
Answer: | From the center of the screw to bar is 4 3/4". The distance between the two jaw pads is 12". These clamps work extremely well! |
Question: | clamp/spread changer is this the old (screw) or new version? shows both in the pictures |
Answer: | I guess the obvious answer is that it is determined by how strong you are. That is, how tight can you make it physically. I will tell you that I'm a woodworker and I've got a full set of these F-clamps and use them everyday. I've never had anything I've clamped down or together has ever come loose. Good clamps. As good as Bessey clamps, but cost less. |
Question: | Can it be used to push? Or open |
Answer: | No it does not spread. It is a great clamp though. |
Question: | Do these come with the little or big pads |
Answer: | Much too heavy to be aluminum. |

User questions & answers
Question: | Are these good for clamping corian pieces together |
Answer: | It seems to be a hard poly material that the snow and ice does not stick to. I was amazes when I ordered these shovels at their construction. Usually it's hard to beleive in the hype of most things but reality is they are that good. I ordered three and will order up again next winter of 2019 / 2020. |
Question: | Has anyone tried to put glue in the sleeves so they don't come off? that's what I have done |
Answer: | There is no metal on the bucket/scoop part. |
Question: | Could I use these to secure a piece of veneer that needs to be glued back on? Tia |

Question: | How wide are these clamps |

User questions & answers
Question: | Do these clamps come with the bench dog attachment shown in the video |
Answer: | I did not. The 10 year manufacture warranty covers everything. All the 3 party warranties that you are asked about when buying on Amazon would be inferior IMHO as Vitamix stands by their product. |
Question: | Has anyone used type 201b toggle clamp to hold garage door tightly closed |
Answer: | The wireless connectivity is more of a gimmick than anything, the idea is you can walk away while blending something, but the blend is so quick it's not needed, almost everything is under a minute. The one advantage possibly would be soups, which take over 5 minutes, however I haven't tried since the app gets poor ratings. The Ascent series is quieter than the Explorian series, and you are getting a ten year warranty with the Ascent. The units that come with a 64oz container have 2.2 horsepower, while units that come with the 48oz container are 2 horsepower. Both old and new have different sized containers that can be used on the units depending on preference. The Ascent series is supposed to be able to detect different size containers (i.e. 64oz, 48oz, 20oz, 8oz) and adjust the power accordingly. The Ascent series is the only model that has an 8oz cup option if you're looking for small batches, and has a more simplified design for the 20oz personal travel cup. |
Question: | What is the clamping capacity of these toggle clamp |
Answer: | The container is made of plastic |
Question: | What range of stock thickness will these clamp |
Answer: | Can handle frozen goodies very well. I tend to start slow before I hit max speed. Clean up is easy. Inside is spacious, no tight corners, which makes it easier to clean. |

Question: | Can the handle be turned a full 360° when the clamp foot/dogs are setting on the bench without being on the edge of the bench |
Answer: | there 2 24" clamps |
Question: | Can you please confirm a 42" tabletop glue-up with these clamps |
Answer: | There is no “made in” designations on the clamp, but the current parent company is Chinese, so a good bet would be that at least some of the components are manufactured in China. Of course that’s just my speculation. Nevertheless it’s a solid product by what was once a well regarded USA manufacturer. |
