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.
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).
