Full-polish body with a wide, flat hook jaw for pipe work. Drop it off scaffolding; pick it up and keep turning.

Questions buyers ask about this tool

The questions importers, distributors and tool programs send us — answered here, and answered live by the online assistant in the corner of this page.

Does the jaw loosen over time?
The worm thread is wide-lead and self-cleaning — grit rides out instead of packing in. Field returns for jaw slack run under 0.2 % of units.
Metric and SAE both marked?
Yes, on both faces, etched not printed — the markings outlast the chrome.
Can we get it in black?
Black-phosphate finish with laser marking from 500 pcs. Popular for tactical and industrial-catalog programs.
