Perforated band and hex screw — the most widely specified clamp in the world.

The American type (SAE J1508) is a perforated band driven by a slotted hex screw. It is inexpensive, universally understood and covers an enormous size range, which is why it remains the default clamp on automotive, agricultural and general industrial assemblies.
We supply 201 and 304 stainless bands with zinc-plated or stainless screws, in widths from 8 mm to 12.7 mm. The housing is riveted, and pull-off torque is tested on every production lot.
