Frequently Asked Questions:

Q. Does the brand offer pneumatic hold down toggle clamps in other styles?

A. Yes, apart from Destaco 847-U pneumatic hold down clamp, the brand also offers solid bar style pneumatic clamps (Destaco 847-S pneumatic clamp) as well.

Q. What is a pneumatic toggle clamp?

A. Destaco pneumatic hold down toggle clamps are pneumatically operated clamps that are used for various applications including welding, woodworking, tensioning devices and various assembly & testing operations.

Q. How do vertical hold down toggle clamps work?

A. Pneumatic hold down action clamps, such as Destaco 847-U clamp, feature a pneumatic cylinder with a piston type configuration. They feature an air supply line that is fed to the clamp cylinder through an input port. The hands free clamping operation is achieved by adjusting the input air supply.

Q. Is clamp a tool?

A. Clamps are application flexible tools. They serve to hold a workpiece securely in its place for temporary operations. These are used in a range of applications, such as furniture making, metal working, construction, carpentry and welding.

Q. What does holding capacity mean in terms of clamps?

A. The holding force or holding capacity depicts the clamp's capability to hold down the equipment or sheet metal on the assembly line or during any other manufacturing process.

Q. Which grease is recommended for use with Destaco clamps when rebuilding?

A. Whenever you're dealing with the brand's mechanical clamps, it is recommended to use a coupling grease like Mobil XTC.

Q. What does clamping force mean?

A. Clamping force is the amount of force actually applied to a workpiece by closing & locking the clamp. It is normally less than the stated holding capacity. The actual clamping force depends on various factors, such as cylinder bore, cylinder area, spindle position (clamping arm length) and available air pressure. In most cases, the clamping force is approximately 2 to 3 times the force exerted by a pneumatic cylinder.

Q. Are Destaco clamps rust resistant?

A. Yes, carbon steel clamps from Destaco are zinc plated for withstanding & minimising wear against harsh industrial environments. For applications that require clamping in outdoor conditions, stainless steel clamps are also available.
