     HI-TORQUE - Heavy Duty Clamps

Bigger, heavier and stronger than our premium aircraft-grade Aero-Seal

100% U.S. made components including 300 series stainless steel in the band  - substantially wider and thicker than almost all industrial grade clamps. 

Heavy-gauge housing is orbitally riveted to a unique saddle, engineered so that eight screw threads are simultaneously engaged in the band for incredible torquing drive by the standard 410 grade stainless steel 5/16" hex screw. 

  • Features eight screw threads - screw is always engaged with band slots.

This is the original and still the highest torque rated worm-drive clamp available in the world!  Use it where conventional clamps are inadequate or in applications where double and triple clamping is now needed.


 

Standard Series -- (HTM - - - Series)

Made in a range of stock sizes for convenient adjustment around standard diameters (typically in OEM or other production assembly work).

 

Liner Series -- (HTM - - - L Series)

Identical with HTM series except that the single-piece band is extended underneath the adjustment slots to protect silicone or other soft-surface materials.

 

Multiples Sizes (HP - - - Series)

This special series of Hi-Torque clamps offers a greatly expanded working diameter range by adding extra perforations to the band: eg. HP 4 covers working diameters normally covered by HTM-500, HTM-550 and HTM-600.  Only 4 sizes covers working diameters from 1-1/4" (32 mm) to 9-1/8" (232 mm).
